Renamed some values in core_names i.e Some DH specific names were changed to use DH instead of FFC. Added some strings values related to RSA keys. Moved set_params related docs out of EVP_PKEY_CTX_ctrl.pod into its own file. Updated Keyexchange and signature code and docs. Moved some common DSA/DH docs into a shared EVP_PKEY-FFC.pod. Moved Ed25519.pod into EVP_SIGNATURE-ED25519.pod and reworked it. Added some usage examples. As a result of the usage examples the following change was also made: ec allows OSSL_PKEY_PARAM_USE_COFACTOR_ECDH as a settable gen parameter.

=head1 NAME
|
|
|
|
OSSL_PROVIDER-legacy - OpenSSL legacy provider
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The OpenSSL legacy provider supplies OpenSSL implementations of algorithms
|
|
that have been deemed legacy. Such algorithms have commonly fallen out of
|
|
use, have been deemed insecure by the cryptography community, or something
|
|
similar.
|
|
|
|
We can consider this the retirement home of cryptographic algorithms.
|
|
|
|
=head2 Properties
|
|
|
|
The implementations in this provider specifically has this property
|
|
defined:
|
|
|
|
=over 4
|
|
|
|
=item "provider=legacy"
|
|
|
|
=back
|
|
|
|
It may be used in a property query string with fetching functions such as
|
|
L<EVP_MD_fetch(3)> or L<EVP_CIPHER_fetch(3)>, as well as with other
|
|
functions that take a property query string, such as
|
|
L<EVP_PKEY_CTX_new_from_name(3)>.
|
|
|
|
It isn't mandatory to query for any of these properties, except to
|
|
make sure to get implementations of this provider and none other.
|
|
|
|
=head1 OPERATIONS AND ALGORITHMS
|
|
|
|
The OpenSSL legacy provider supports these operations and algorithms:

|
|
When algorithms for other operations start appearing, the
|
|
following =head2 titles are appropriate to use:
|
|
|
|
- Symmetric Ciphers
|
|
|
|
- Message Authentication Code (MAC)
|
|
|
|
- Key Derivation Function (KDF)
|
|
|
|
- Key Exchange
