DESCRIPTIONThe EVP_PKEY_CTX_new() function allocates public key algorithm context using the algorithm specified in pkey and ENGINE e. The EVP_PKEY_CTX_new_id() function allocates public key algorithm context using the algorithm specified by id and ENGINE e. It is normally used when no EVP_PKEY structure is associated with the operations, for example during parameter generation of key generation for some algorithms. EVP_PKEY_CTX_dup() duplicates the context ctx. EVP_PKEY_CTX_free() frees up the context ctx. If ctx is NULL, nothing is done. NOTESThe EVP_PKEY_CTX structure is an opaque public key algorithm context used by the OpenSSL high-level public key API. Contexts MUST NOT be shared between threads: that is it is not permissible to use the same context simultaneously in two threads. RETURN VALUESEVP_PKEY_CTX_new(), EVP_PKEY_CTX_new_id(), EVP_PKEY_CTX_dup() returns either the newly allocated EVP_PKEY_CTX structure of NULL if an error occurred. EVP_PKEY_CTX_free() does not return a value. SEE ALSOHISTORYThese functions were added in OpenSSL 1.0.0. COPYRIGHTCopyright 2006-2020 The OpenSSL Project Authors. All Rights Reserved.
