|
|
|

|
|
<p>EVP_PKEY_CTX_get0_libctx() and EVP_PKEY_CTX_get0_propq() obtain the OSSL_LIB_CTX and property query string values respectively that were associated with the EVP_PKEY_CTX when it was constructed.</p>
|
||
|
|
|
||
|
|
<p>EVP_PKEY_CTX_get0_provider() returns the provider associated with the ongoing <b>EVP_PKEY_CTX</b> operation. If the operation is performed by en <b>ENGINE</b>, this function returns NULL.</p>

|

|
|
|

|
|
<p>EVP_PKEY_CTX_get0_libctx() and EVP_PKEY_CTX_get0_propq() functions return the OSSL_LIB_CTX and property query string associated with the EVP_PKEY_CTX or NULL if they are not set. The returned values should not be freed by the caller.</p>
|
||
|
|
|
||
|
|
<p>EVP_PKEY_CTX_get0_provider() returns a provider if an operation performed by a provider is ongoing, otherwise NULL.</p>
