<p>EVP_PKEY_CTX_get0_pkey() is used to access the <b>EVP_PKEY</b> associated with the given <b>EVP_PKEY_CTX</b> <i>ctx</i>. The <b>EVP_PKEY</b> obtained is the one used for creating the <b>EVP_PKEY_CTX</b> using either <a href="../man3/EVP_PKEY_CTX_new.html">EVP_PKEY_CTX_new(3)</a> or <a href="../man3/EVP_PKEY_CTX_new_from_pkey.html">EVP_PKEY_CTX_new_from_pkey(3)</a>.</p>
|
||
|
|
|
||
|
|
<p>EVP_PKEY_CTX_get0_peerkey() is used to access the peer <b>EVP_PKEY</b> associated with the given <b>EVP_PKEY_CTX</b> <i>ctx</i>. The peer <b>EVP_PKEY</b> obtained is the one set using either <a href="../man3/EVP_PKEY_derive_set_peer.html">EVP_PKEY_derive_set_peer(3)</a> or <a href="../man3/EVP_PKEY_derive_set_peer_ex.html">EVP_PKEY_derive_set_peer_ex(3)</a>.</p>

|
|

|
|
<p>EVP_PKEY_CTX_get0_pkey() returns the <b>EVP_PKEY</b> associated with the EVP_PKEY_CTX or NULL if it is not set.</p>
|
||
|
|
|
||
|
|
<p>EVP_PKEY_CTX_get0_peerkey() returns the peer <b>EVP_PKEY</b> associated with the EVP_PKEY_CTX or NULL if it is not set.</p>
|
||
|
|
|
||
|
|
<p>The returned EVP_PKEY objects are owned by the EVP_PKEY_CTX, and therefore should not explicitly be freed by the caller.</p>
|
||
|
|
|
||
|
|
<p>These functions do not affect the EVP_PKEY reference count. They merely act as getter functions, and should be treated as such.</p>
