outbuffer to store the derived key, must be of out_len bytes
out_lenthe desired length of the key to produce
passphrasethe password to derive the key from
salta randomly chosen salt
salt_lenlength of salt in bytes
milliseconds_to_runif iterations is zero, then instead the PBKDF is run until milliseconds_to_run milliseconds has passed

Returns
0 on success, a negative value on failure

Generates ElGamal key pair. Caller has a control over key length and order of a subgroup 'q'. Function is able to use two types of primes:

  • if pbits-1 == qbits then safe primes are used for key generation
  • otherwise generation uses group of prime order
Parameters

On input *out_len is number of bytes in out[] On output *out_len is number of bytes written (or required) If out is not big enough no output is written, *out_len is set and 1 is returned Returns 0 on success and sets If some other error occurs a negative integer is returned.
