Keys are either:
- Random bit patterns generated using a suitable cryptograph (P)RNG,
e.g. read from /dev/urandom or /dev/random.
- Password-based but strengthened via a suitable KDF (key-derivation
function). It is here that you combine a 'salt' value with the user's
password, and for this OpenSSL includes (the yet to be documented)
PKCS5_PBKDF2_HMAC_SHA1 declared in <openssl/evp.h>
int PKCS5_PBKDF2_HMAC_SHA1(const char *pass, int passlen,
unsigned char *salt, int saltlen, int iter,
int keylen, unsigned char *out);
the iteration count is often 1000, but should probably be higher for
new applications.
