=head1 NAME
|
|
|
|
EVP_SIGNATURE-ECDSA - The EVP_PKEY ECDSA signature implementation.
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Support for computing ECDSA signatures.
|
|
See L<EVP_PKEY-EC(7)> for information related to EC keys.
|
|
|
|
=head2 ECDSA 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().
