Documentation
botan_privkey_create_elgamal Source #
Arguments
| :: Ptr BotanPrivKey | key: handler to the resulting key |
| -> BotanRNG | rng: initialized PRNG |
| -> CSize | pbits: length of the key in bits. Must be at least 1024 |
| -> CSize | qbits: order of the subgroup. Must be at least 160 |
| -> IO CInt |
|
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
botan_pubkey_load_elgamal Source #
Arguments
| :: Ptr BotanPubKey | key: variable populated with key material |
| -> BotanMP | p: prime order of a Z_p group |
| -> BotanMP | g: group generator |
| -> BotanMP | y: private key |
| -> IO CInt | 0 on success, a negative value on failure |
Loads ElGamal private key
botan_privkey_load_elgamal Source #
Arguments
| :: Ptr BotanPrivKey | key: variable populated with key material |
| -> BotanMP | p: prime order of a Z_p group |
| -> BotanMP | g: group generator |
| -> BotanMP | x: public key |
| -> IO CInt | 0 on success, a negative value on failure |
