=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 algorithm specified in I<pkey> and ENGINE I<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 generation for some algorithms.
using the algorithm specified by I<id> and ENGINE I<e>.
EVP_PKEY_CTX_dup() duplicates the context B<ctx>.
The EVP_PKEY_CTX_new_provided() function allocates a public key
algorithm context using the algorithm specified by I<name> and the
property query I<propquery>. The strings aren't duplicated, so they
must remain unchanged for the lifetime of the returned B<EVP_PKEY_CTX>
or of any of its duplicates.
EVP_PKEY_CTX_free() frees up the context B<ctx>.
If B<ctx> is NULL, nothing is done.
EVP_PKEY_CTX_new_id() and EVP_PKEY_CTX_new_provided() are normally
used when no B<EVP_PKEY> structure is associated with the operations,
