salt generation code. He also urged using better random source and making possible to choose using bcrypt and xdes rounds more easily. So, here's patch: * For all salt generation, use Solar Designer's own code. This is mostly due fact that his code is more fit for get_random_bytes() style interface. * New function: gen_salt(type, rounds). This lets specify iteration count for algorithm. * random.c: px_get_random_bytes() function. Supported randomness soure: /dev/urandom, OpenSSL PRNG, libc random() Default: /dev/urandom. * Draft description of C API for pgcrypto functions. New files: API, crypt-gensalt.c, random.c Marko Kreen
