|
|
|
||
|
|
EVP_SIGNATURE-DSA
|
||
|
|
- The B<EVP_PKEY> DSA signature implementation
|
||
|
|
|
||
|
|
=head1 DESCRIPTION
|
||
|
|
|
||
|
|
Support for computing DSA signatures.
|
||
|
|
See L<EVP_PKEY-DSA(7)> for information related to DSA keys.
|
||
|
|
|
||
|
|
=head2 Signature Parameters
|
||
|
|
|
||
|
|
The following signature parameters can be set using EVP_PKEY_CTX_set_params().
|
||
|
|
This may be called after EVP_PKEY_sign_init() or EVP_PKEY_verify_init(),
|
||
|
|
and before calling EVP_PKEY_sign() or EVP_PKEY_verify().

|
|
||
|
|
=item "properties" (B<OSSL_SIGNATURE_PARAM_PROPERTIES>) <UTF8 string>
|
||
|
|

|
|
EVP_PKEY_CTX_get_params().
