Webcrypt is a POSIX C library function. It is typically used to compute the hash of user account passwords. The function outputs a text string which also encodes the salt (usually the first two characters are the salt itself and the rest is the hashed result), and identifies the hash algorithm used (defaulting to the "traditional" one explained below). This output string … WebBlowfish features a 64-bit block size and takes a variable-length key, from 32 bits to 448 bits.
