 /** 
- * @file lltexturebar.h
- * @brief LLTextureBar class definition
+ * @file llblowfishcipher.h
+ * @brief A symmetric block cipher, designed in 1993 by Bruce Schneier.
+ * We use it because it has an 8 byte block size, allowing encryption of
+ * two UUIDs and a timestamp (16x2 + 4 = 36 bytes) with only 40 bytes of
+ * output.  AES has a block size of 32 bytes, so this would require 64 bytes.
