|
|---|
| 8 |
|
|---|
| 9 | #include <openssl/evp.h>
|
|---|
| 10 | int EVP_PKEY_digestsign_supports_digest(EVP_PKEY *pkey, OSSL_LIB_CTX *libctx,

| 13 | =head1 DESCRIPTION
|
|---|
| 14 |
|
|---|
| 15 | The EVP_PKEY_digestsign_supports_digest() function queries whether the message
|
|---|
| 16 | digest I<name> is supported for public key signature operations associated with
|
|---|
| 17 | key I<pkey>. The query is done within an optional library context I<libctx> and
|
|---|
| 18 | with an optional property query I<propq>.
|

| 19 |
|
|---|
| 20 | =head1 RETURN VALUES
|
|---|
| 21 |
|
|---|
| 22 | The EVP_PKEY_digestsign_supports_digest() function returns 1 if the message
|
|---|
| 23 | digest algorithm identified by I<name> can be used for public key signature
|
|---|
| 24 | operations associated with key I<pkey> and 0 if it cannot be used. It returns
|
|---|
| 25 | a negative value for failure.
