derive key from password
If timeInSeconds != 0, will iterate until time elapsed, as measured by ThreadUserTimer Returns actual iteration count, which is equal to iterations if timeInSeconds == 0, and not less than iterations otherwise.
Implemented in PKCS12_PBKDF< T >, PKCS5_PBKDF2_HMAC< T >, and PKCS5_PBKDF1< T >.
