+2002-09-16  Werner Koch  <wk@gnupg.org>
+        * arcfour.c (do_encrypt_stream): Use register modifier and modulo.
+        According to Nikos Mavroyanopoulos this increases perfromace on
+        i386 system noticable.  And I always tought gcc is clever enough.

+        * rmd160.c (transform): Ditto.

+        * primegen.c, elgamal.c, dsa.c (progress): Do not print anything
+        by default.  Pass an extra identifying string to the callback and

+2002-05-17  Werner Koch  <wk@gnupg.org>

+        * rndw32.c (rndw32_constructor): Ditto.
+        * tiger.c (tiger_constructor): Ditto.
+        * Makefile.am: Removed all dynamic loading stuff.
+        * dynload.c: Ditto. Now only used for the constructor system.
+2002-05-15  Werner Koch  <wk@gnupg.org>
+        * random.c (gcry_random_bytes,gcry_random_bytes_secure)
+        (gcry_randomize): Make sure we are initialized.
+2002-05-14  Werner Koch  <wk@gnupg.org>
+        Changed license of most files to the LGPL.

+        * cipher.c (gcry_cipher_map_name): Map "RIJNDAEL" to "AES".
+        * rijndael.c (rijndael_get_info): We do only support a 128 bit
+        blocksize so it makes sense to change the algorithm strings to
+        AES.
+        * tiger.c (tiger_final): Removed superfluous token pasting operators.
+        * md5.c (md5_final): Ditto.
+2002-04-30  Werner Koch  <wk@gnupg.org>

+2002-03-18  Werner Koch  <wk@gnupg.org>
+        * random.c (initialize): Initialize the new pool lock mutex.
+        (_gcry_fast_random_poll): Add locking and moved main

+2002-02-18  Werner Koch  <wk@gnupg.org>

+        around to make the function more robust.
+2002-02-08  Werner Koch  <wk@gnupg.org>
+        * random.c (add_randomness): Xor new data into the pool and not
+        just copy it.  This avoids any choosen input attacks which are not
+        serious in our setting because an outsider won't be able to mix
+        data in and even then we keep going with a PRNG.  Thanks to Stefan
+        Keller for pointing this out.
+2002-01-04  Werner Koch  <wk@gnupg.org>
+        * pubkey.c (gcry_pk_genkey): Do not release skey - it is static.
+        * primegen.c (gen_prime): Of course we should use set_bit
+        and not set_highbit to set the second high bit.
+2001-12-18  Werner Koch  <wk@gnupg.org>
+        * rsa.c (generate): Loop until we find the exact modulus size.
+        Changed the exponent to 41.

+        (search_oid): .. new function.
+2001-12-10  Werner Koch  <wk@gnupg.org>
+        * pubkey.c (gcry_pk_encrypt): Find the signature algorithm by name
+        and not by number.
+        
+        * pubkey.c (gcry_pk_encrypt,gcry_pk_decrypt,gcry_pk_sign)
+        (gcry_pk_verify,gcry_pk_testkey, gcry_pk_genkey)
+        (gcry_pk_get_nbits): Release the arrays.  Noted by Nikos
+        Mavroyanopoulos.
+2001-12-06  Werner Koch  <wk@gnupg.org>
+        * cipher.c (gcry_cipher_map_name): Look also for OIDs prefixed
+        with "oid."  or "OID.".
+2001-12-05  Werner Koch  <wk@gnupg.org>
+        * pubkey.c (algo_info_table): Fixed entry for openpgp-rsa. 
+2001-11-24  Werner Koch  <wk@gnupg.org>
+        * pubkey.c: Added the rsaEncryption OID to the tables.
+        (sexp_to_key): Add an arg to return the index of the algorithm,
+        changed all callers.
+        (gcry_pk_sign): Find the signature algorithm by name and not by
+        number.
+        (gcry_pk_get_nbits): Fixed so that we can now really pass a secret
+        key to get the result.
+        
+        * md.c (gcry_md_map_name): Look also for OIDs prefixed with "oid."
+        or "OID." so that an OID string can be used as an S-Exp token.
+2001-11-20  Werner Koch  <wk@gnupg.org>
+        * md.c (gcry_md_map_name): Lookup by OID if the the name begins
+        with a digit.
+        (oid_table): New.
+        
+2001-11-16  Werner Koch  <wk@gnupg.org>
+        * md.c (gcry_md_info): New operator GCRYCTL_IS_ALGO_ENABLED.
+2001-11-07  Werner Koch  <wk@gnupg.org>
+        * md.c (gcry_md_hash_buffer): Close the handle which was left open
+        for algorithms other than rmd160.
+2001-08-08  Werner Koch  <wk@gnupg.org>
+        * rndw32.c (gather_random): Use toolhelp in addition to the NT
+        gatherer for Windows2000.  Suggested by Sami Tolvanen.
+        * random.c (read_pool): Fixed length check, this used to be one
+        byte to strict.  Made an assert out of it because the caller has
+        already made sure that only poolsize bytes are requested.
+        Reported by Marcus Brinkmann.
+2001-08-03  Werner Koch  <wk@gnupg.org>
+        * cipher.c (cipher_encrypt, cipher_decrypt): Prepare to return
+        errors. We have to change the interface to all ciphers to make
+        this really work but we should do so to prepare for hardware
+        encryption modules.
+        (gcry_cipher_encrypt, gcry_cipher_decrypt): Return the error and
+        set lasterr. 
+        (gcry_cipher_ctl): Make sure that errors from setkey are returned.
+2001-08-02  Werner Koch  <wk@gnupg.org>
+        * rndlinux.c (gather_random): casted a size_t arg to int so that
+        the format string is correct.  Casting is okay here and avoids

+        getrusage.
+        * rndunix.c: Add a signal.h header to avoid warnings on Solaris 7
+        and 8.
+        * tiger.c (print_abc,print_data): Removed.
+        * rijndael.c, des.c, blowfish.c, twofish.c, cast5.c, arcfour.c
+        (burn_stack): New.  Add wrappers for most functions to be able to
+        call burn_stack after the function invocation. This methods seems
+        to be the most portable way to zeroise the stack used. It does
+        only work on stack frame based machines but it is highly portable
+        and has no side effects.  Just setting the automatic variables at
+        the end of a function to zero does not work well because the
+        compiler will optimize them away - marking them as volatile would
+        be bad for performance.
+        * md5.c, sha1.c, rmd160.c, tiger.c (burn_stack): Likewise.
+        * random.c (burn_stack): New.
+        (mix_pool): Use it here to burn the stack of the mixblock function.
+        * primegen.c (_gcry_generate_elg_prime): Freed q at 3 places.
+        Thanks to Tommi Komulainen.
+        * arcfour.c (arcfour_setkey): Check the minimim keylength against
+        bytes and not bits.
+        (selftest): Must reset the key before decryption. 
+2001-05-31  Werner Koch  <wk@gnupg.org>
+        * sha1.c (sha1_init): Made static.
+        Changed all g10_ prefixed function names as well as some mpi_
+        function names to cope with the introduced naming changes.
+        
+        * md.c (prepare_macpads): Made key const.
+2001-05-28  Werner Koch  <wk@gnupg.org>
+        * rndegd.c (gather_random): Removed the use of tty_printf.
+2001-03-29  Werner Koch  <wk@gnupg.org>
+        * md5.c (md5_final): Fixed calculation of hashed length.  Thanks
+        to disastry@saiknes.lv for pointing out that it was horrible wrong
+        for more than 512MB of input.
+        * sha1.c (sha1_final): Ditto.
+        * rmd160.c (rmd160_final): Ditto.
+        * tiger.c (tiger_final): Ditto.
+        * blowfish.c (encrypt,do_encrypt): Changed name to do_encrypt to
+        avoid name clashes with an encrypt function in stdlib.h of
+        Dynix/PIX.  Thanks to Gene Carter.
+        * elgamal.c (encrypt,do_encrypt): Ditto.
+        * twofish.c (gnupgext_enum_func): Use only when when compiled as a
+        module.
+        * rijndael.c (gnupgext_enum_func): Ditto.
+        * tiger.c (tiger_get_info): Return "TIGER192" and not just
+        "TIGER".  By Edwin Woudt.
+        
+        * random.c: Always include time.h - standard requirement.  Thanks
+        to James Troup.
+        * rndw32.c: Fixes to the macros.
+2001-01-11  Werner Koch  <wk@gnupg.org>
+        * cipher.c (cipher_encrypt,gcry_cipher_encrypt): Use blocksize and
+        not 8.
+2000-12-19  Werner Koch  <wk@gnupg.org>
+        Major change:
+        Removed all GnuPG stuff and renamed this piece of software
+        to gcrypt. 
+2000-11-14  Werner Koch  <wk@gnupg.org>
+        * dsa.c (test_keys): Replaced mpi_alloc by gcry_mpi_new and

+        (setup_cipher_table): Add Arcfour.
+        (gcry_cipher_open): Kludge to allow stream mode.
+Wed Oct  4 13:16:18 CEST 2000  Werner Koch  <wk@openit.de>
+        * sha1.c (transform): Use rol() macro.  Actually this is not needed
+        for a newer gcc but there are still aoter compilers.
+        * rsa.c (test_keys): Use new random function. 
+        * md.c (gcry_md_setkey): New function to overcome problems with

+        * rsa.c: Changed the comment about the patent.
+        (secret): Speed up by using the CRT.  For a 2k keys this
+        is about 3 times faster.
+        (stronger_key_check): New but unused code to check the secret key.
+        * Makefile.am: Included rsa.[ch].
+        * pubkey.c: Enabled RSA support.
+        (pubkey_get_npkey): Removed RSA workaround.
+Mon Jul 31 10:04:47 CEST 2000  Werner Koch  <wk@openit.de>
+  * pubkey.c: Replaced all gcry_sexp_{car,cdr}_{data,mpi} by the new
+  gcry_sexp_nth_{data,mpi} functions.

+  * pubkey.c (exp_to_key,sexp_to_sig,sexp_to_enc,gcry_pk_encrypt,
+    gcry_pk_decrypt,gcry_pk_sign,gcry_pk_genkey): Changed to work with
+    the new S-Exp interface.
+Mon Jul 17 16:35:47 CEST 2000  Werner Koch  <wk@>
+  * random.c (gather_faked): Replaced make_timestamp by time(2) again.
+Fri Jul 14 19:38:23 CEST 2000  Werner Koch  <wk@>
+  * md.c (gcry_md_ctl): Support GCRYCTL_{START,STOP}_DUMP.
+  * Makefile.am: Never compile mingw32 as module.
+  * Makefile.am: Tweaked module build and removed libtool
+  * Makefile.am:  Replaced -O1 by -O. Suggested by Alec Habig.
+  * elgamal.c (sign): Removed inactive code.
+  * rsa.c, rsa.h: New based on the old module version (only in CVS for now).
+  * pubkey.c (setup_pubkey_table): Added commented support for RSA.
+  * rndunix.c (waitpid): New. For UTS 2.1.  All by Dave Dykstra.
+  (my_popen): Do the FD_CLOEXEC only if it is available
+  (start_gatherer): Cope with missing _SC_OPEN_MAX
+  * rndunix.c: Add some more headers for QNX. By Sam Roberts.
+  * rndegd.c (gather_random): Shortcut level 0.
+  * rndunix.c (gather_random): Ditto.
+  * rndw32.c (gather_random): Ditto.

+  system which support this POSIX.4 fucntion. By Sam Roberts.
+  * random.c (read_seed_file): Removed the S_ISLNK test becuase it
+  is already covered by !S_ISREG and is not defined in Unixware.
+  Reported by Dave Dykstra.
+  (update_random_seed_file): Silently ignore update request when pool
+  is not filled.
+  * random.c (read_seed_file): New.
+  (set_random_seed_file): New.
+  (read_pool): Try to read the seeding file.
+  (update_random_seed_file): New.
+  (read_pool): Do an initial extra seeding when level 2 quality random
+  is requested the first time.  This requestes at least POOLSIZE/2 bytes
+  of entropy.  Compined with the seeding file this should make normal
+  random bytes cheaper and increase the quality of the random bytes
+  used for key generation.
+  * random.c (read_pool): Print a more friendly error message in
+  cases when too much random is requested in one call.
+  * random.c (fast_random_poll): Check whether RUSAGE_SELF is defined;
+  this is not the case for some ESIX and Unixware, although they have
+  getrusage().
+  * primegen.c (generate_elg_prime): All primes are now generated with
+  the lowest random quality level.  Because they are public anyway we

+ *  U S A G E
+ * ===========
+ *
+ * For DES or Triple-DES encryption/decryption you must initialize a proper
+ * encryption context with a key.
+ *
+ * A DES key is 64bit wide but only 56bits of the key are used. The remaining
+ * bits are parity bits and they will _not_ checked in this implementation, but
+ * simply ignored.
+ *
+ * For Triple-DES you could use either two 64bit keys or three 64bit keys.
+ * The parity bits will _not_ checked, too.
+ *
+ * After initializing a context with a key you could use this context to
+ * encrypt or decrypt data in 64bit blocks in Electronic Codebook Mode.
+ *
+ * (In the examples below the slashes at the beginning and ending of comments
+ * are omited.)
+ *
+ * DES Example
+ * -----------
+ *     unsigned char key[8];
+ *     unsigned char plaintext[8];
+ *     unsigned char ciphertext[8];
+ *     unsigned char recoverd[8];
+ *     des_ctx context;
+ *
+ *     * Fill 'key' and 'plaintext' with some data *
+ *     ....
+ *
+ *     * Set up the DES encryption context *
+ *     des_setkey(context, key);
+ *
+ *     * Encrypt the plaintext *
+ *     des_ecb_encrypt(context, plaintext, ciphertext);
+ *
+ *     * To recover the orginal plaintext from ciphertext use: *
+ *     des_ecb_decrypt(context, ciphertext, recoverd);
+ *
+ *
+ * Triple-DES Example
+ * ------------------
+ *     unsigned char key1[8];
+ *     unsigned char key2[8];
+ *     unsigned char key3[8];
+ *     unsigned char plaintext[8];
+ *     unsigned char ciphertext[8];
+ *     unsigned char recoverd[8];
+ *     tripledes_ctx context;
+ *
+ *     * If you would like to use two 64bit keys, fill 'key1' and'key2'
+ *       then setup the encryption context: *
+ *     tripledes_set2keys(context, key1, key2);
+ *
+ *     * To use three 64bit keys with Triple-DES use: *
+ *     tripledes_set3keys(context, key1, key2, key3);
+ *
+ *     * Encrypting plaintext with Triple-DES *
+ *     tripledes_ecb_encrypt(context, plaintext, ciphertext);
+ *
+ *     * Decrypting ciphertext to recover the plaintext with Triple-DES *
+ *     tripledes_ecb_decrypt(context, ciphertext, recoverd);
+ *
+ *
+ * Selftest
+ * --------
+ *     char *error_msg;
+ *
+ *     * To perform a selftest of this DES/Triple-DES implementation use the
+ *       function selftest(). It will return an error string if their are
+ *       some problems with this library. *
+ *
+ *     if ( (error_msg = selftest()) )
+ *     {
+ *         fprintf(stderr, "An error in the DES/Tripple-DES implementation occured: %s\n", error_msg);
+ *         abort();
+ *     }

+ * RIPEMD-160 is not patented, see (as of 25.10.97)
+ *   http://www.esat.kuleuven.ac.be/~bosselae/ripemd160.html

+ *
+ * Pseudo-code for RIPEMD-160
+ *
+ * RIPEMD-160 is an iterative hash function that operates on 32-bit words.
+ * The round function takes as input a 5-word chaining variable and a 16-word
+ * message block and maps this to a new chaining variable. All operations are
+ * defined on 32-bit words. Padding is identical to that of MD4.

+/* The structure containing information on random-data sources.  Each
+ * record contains the source and a relative estimate of its usefulness
+ * (weighting) which is used to scale the number of kB of output from the
+ * source (total = data_bytes / usefulness).  Usually the weighting is in the
+ * range 1-3 (or 0 for especially useless sources), resulting in a usefulness
+ * rating of 1...3 for each kB of source output (or 0 for the useless
+ * sources).
+ *
+ * If the source is constantly changing (certain types of network statistics
+ * have this characteristic) but the amount of output is small, the weighting
+ * is given as a negative value to indicate that the output should be treated
+ * as if a minimum of 1K of output had been obtained.  If the source produces
+ * a lot of output then the scale factor is fractional, resulting in a
+ * usefulness rating of < 1 for each kB of source output.
+ *
+ * In order to provide enough randomness to satisfy the requirements for a
+ * slow poll, we need to accumulate at least 20 points of usefulness (a
+ * typical system should get about 30 points).
+ *
+ * Some potential options are missed out because of special considerations.
+ * pstat -i and pstat -f can produce amazing amounts of output (the record
+ * is 600K on an Oracle server) which floods the buffer and doesn't yield
+ * anything useful (apart from perhaps increasing the entropy of the vmstat
+ * output a bit), so we don't bother with this.  pstat in general produces
+ * quite a bit of output, but it doesn't change much over time, so it gets
+ * very low weightings.  netstat -s produces constantly-changing output but
+ * also produces quite a bit of it, so it only gets a weighting of 2 rather
+ * than 3.  The same holds for netstat -in, which gets 1 rather than 2.
+ *
+ * Some binaries are stored in different locations on different systems so
+ * alternative paths are given for them.  The code sorts out which one to
+ * run by itself, once it finds an exectable somewhere it moves on to the
+ * next source.  The sources are arranged roughly in their order of
+ * usefulness, occasionally sources which provide a tiny amount of
+ * relatively useless data are placed ahead of ones which provide a large
+ * amount of possibly useful data because another 100 bytes can't hurt, and
+ * it means the buffer won't be swamped by one or two high-output sources.
+ * All the high-output sources are clustered towards the end of the list
+ * for this reason.  Some binaries are checked for in a certain order, for
+ * example under Slowaris /usr/ucb/ps understands aux as an arg, but the
+ * others don't.  Some systems have conditional defines enabling alternatives
+ * to commands which don't understand the usual options but will provide
+ * enough output (in the form of error messages) to look like they're the
+ * real thing, causing alternative options to be skipped (we can't check the
+ * return either because some commands return peculiar, non-zero status even
+ * when they're working correctly).
+ *
+ * In order to maximise use of the buffer, the code performs a form of run-
+ * length compression on its input where a repeated sequence of bytes is
+ * replaced by the occurrence count mod 256.  Some commands output an awful
+ * lot of whitespace, this measure greatly increases the amount of data we
+ * can fit in the buffer.
+ *
+ * When we scale the weighting using the SC() macro, some preprocessors may
+ * give a division by zero warning for the most obvious expression
+ * 'weight ? 1024 / weight : 0' (and gcc 2.7.2.2 dies with a division by zero
+ * trap), so we define a value SC_0 which evaluates to zero when fed to
+ * '1024 / SC_0' */

+ * precomputing.  Of course the main saving comes from precomputing the
+ * GF(2^8) multiplication involved in the MDS matrix multiply; by looking
+ * things up in these tables we reduce the matrix multiply to four lookups
+ * and three XORs.  Semi-formally, the definition of these tables is:
+ * mds[0][i] = MDS (q1[i] 0 0 0)^T  mds[1][i] = MDS (0 q0[i] 0 0)^T
+ * mds[2][i] = MDS (0 0 q1[i] 0)^T  mds[3][i] = MDS (0 0 0 q0[i])^T
+ * where ^T means "transpose", the matrix multiply is performed in GF(2^8)
+ * represented as GF(2)[x]/v(x) where v(x)=x^8+x^6+x^5+x^3+1 as described
+ * by Schneier et al, and I'm casually glossing over the byte/word

+/* The exp_to_poly and poly_to_exp tables are used to perform efficient
+ * operations in GF(2^8) represented as GF(2)[x]/w(x) where
+ * w(x)=x^8+x^6+x^3+x^2+1.  We care about doing that because it's part of the
+ * definition of the RS matrix in the key schedule.  Elements of that field
+ * are polynomials of degree not greater than 7 and all coefficients 0 or 1,
+ * which can be represented naturally by bytes (just substitute x=2).  In that
+ * form, GF(2^8) addition is the same as bitwise XOR, but GF(2^8)
+ * multiplication is inefficient without hardware support.  To multiply
+ * faster, I make use of the fact x is a generator for the nonzero elements,
+ * so that every element p of GF(2)[x]/w(x) is either 0 or equal to (x)^n for
+ * some n in 0..254.  Note that that caret is exponentiation in GF(2^8),
+ * *not* polynomial notation.  So if I want to compute pq where p and q are
+ * in GF(2^8), I can just say:
+ *    1. if p=0 or q=0 then pq=0
+ *    2. otherwise, find m and n such that p=x^m and q=x^n
+ *    3. pq=(x^m)(x^n)=x^(m+n), so add m and n and find pq
+ * The translations in steps 2 and 3 are looked up in the tables
+ * poly_to_exp (for step 2) and exp_to_poly (for step 3).  To see this
+ * in action, look at the CALC_S macro.  As additional wrinkles, note that
+ * one of my operands is always a constant, so the poly_to_exp lookup on it
+ * is done in advance; I included the original values in the comments so
+ * readers can have some chance of recognizing that this *is* the RS matrix
+ * from the Twofish paper.  I've only included the table entries I actually
+ * need; I never do a lookup on a variable input of zero and the biggest
+ * exponents I'll ever see are 254 (variable) and 237 (constant), so they'll
+ * never sum to more than 491.  I'm repeating part of the exp_to_poly table
+ * so that I don't have to do mod-255 reduction in the exponent arithmetic.
+ * Since I know my constant operands are never zero, I only have to worry
+ * about zero values in the variable operand, and I do it with a simple
+ * conditional branch.  I know conditionals are expensive, but I couldn't
