| 10 | Support for computing DSA signatures.
|

| 13 | =head2 Signature Parameters
|
|---|
| 14 |
|
|---|
| 15 | The following signature parameters can be set using EVP_PKEY_CTX_set_params().
|
|---|
| 16 | This may be called after EVP_PKEY_sign_init() or EVP_PKEY_verify_init(),
|
|---|
| 17 | and before calling EVP_PKEY_sign() or EVP_PKEY_verify().
