|
| +
|
| +EVP_PKEY_CTX_new, EVP_PKEY_CTX_new_id, EVP_PKEY_CTX_dup, EVP_PKEY_CTX_free - public key algorithm context functions.
|
| +
|
| +=head1 SYNOPSIS
|
| +
|
| + #include <openssl/evp.h>
|
| +
|
| + EVP_PKEY_CTX *EVP_PKEY_CTX_new(EVP_PKEY *pkey, ENGINE *e);
|
| + EVP_PKEY_CTX *EVP_PKEY_CTX_new_id(int id, ENGINE *e);
|
| + EVP_PKEY_CTX *EVP_PKEY_CTX_dup(EVP_PKEY_CTX *ctx);
|
| + void EVP_PKEY_CTX_free(EVP_PKEY_CTX *ctx);
|
| +
|
| +=head1 DESCRIPTION
|
| +
|
| +The EVP_PKEY_CTX_new() function allocates public key algorithm context using
|
| +the algorithm specified in B<pkey> and ENGINE B<e>.
|
| +
|
| +The EVP_PKEY_CTX_new_id() function allocates public key algorithm context
|
| +using the algorithm specified by B<id> and ENGINE B<e>. It is normally used
|
| +when no B<EVP_PKEY> structure is associated with the operations, for example
|
| +during parameter generation of key genration for some algorithms.
|
| +
|
| +EVP_PKEY_CTX_dup() duplicates the context B<ctx>.
|
| +
|
| +EVP_PKEY_CTX_free() frees up the context B<ctx>.
|
| +
|
| +=head1 NOTES
|
| +
|
| +The B<EVP_PKEY_CTX> structure is an opaque public key algorithm context used
|
| +by the OpenSSL high level public key API. Contexts B<MUST NOT> be shared between
|
| +threads: that is it is not permissible to use the same context simultaneously
|
| +in two threads.
|
| +
|
| +=head1 RETURN VALUES
|
| +
|
| +EVP_PKEY_CTX_new(), EVP_PKEY_CTX_new_id(), EVP_PKEY_CTX_dup() returns either
|
| +the newly allocated B<EVP_PKEY_CTX> structure of B<NULL> if an error occurred.
|
| +
|
| +EVP_PKEY_CTX_free() does not return a value.
