.SH "DESCRIPTION"
|
|
Packit |
aea12f |
This function will verify the given signed digest, using the
|
|
Packit |
aea12f |
parameters from the public key. Note that unlike \fBgnutls_privkey_sign_hash()\fP,
|
|
Packit |
aea12f |
this function accepts a signature algorithm instead of a digest algorithm.
|
|
Packit |
aea12f |
You can use \fBgnutls_pk_to_sign()\fP to get the appropriate value.
|

.SH "RETURNS"
|
|
Packit |
aea12f |
In case of a verification failure \fBGNUTLS_E_PK_SIG_VERIFY_FAILED\fP
|
|
Packit |
aea12f |
is returned, and zero or positive code on success. For known to be insecure
|
|
Packit |
aea12f |
signatures this function will return \fBGNUTLS_E_INSUFFICIENT_SECURITY\fP unless
|
|
Packit |
aea12f |
the flag \fBGNUTLS_VERIFY_ALLOW_BROKEN\fP is specified.
