◆ compute_key

BUF_MEM *(* ri_ctx::compute_key) (EVP_PKEY *key, const BUF_MEM *in, BN_CTX *bn_ctx)

Completes a key agreement by computing the shared secret.

Parameters

[in]	key	Object for key computation, usually `&KA_CTX.key`
[in]	in	Public key from the other party
[in]	bn_ctx	(optional)

Returns: Shared secret or NULL in case of an error

Definition at line 238 of file eac.h.

Generates a key pair for key agreement.

Parameters

[in]	key	Object for key generation, usually `&KA_CTX.key`
[in]	bn_ctx	(optional)

Returns: Public key or NULL in case of an error
