   8
   9 Support for computing ECDSA signatures.
  10 See L<EVP_PKEY-EC(7)> for information related to EC keys.

  12 =head2 ECDSA Signature Parameters
  13
  14 The following signature parameters can be set using EVP_PKEY_CTX_set_params().
  15 This may be called after EVP_PKEY_sign_init() or EVP_PKEY_verify_init(),
  16 and before calling EVP_PKEY_sign() or EVP_PKEY_verify().
