.SH NAME
gnutls_x509_crt_verify_data2 \- API function
.SH SYNOPSIS
.B #include <gnutls/x509.h>
.sp
.BI "int gnutls_x509_crt_verify_data2(gnutls_x509_crt_t " crt ", gnutls_sign_algorithm_t " algo ", unsigned int " flags ", const gnutls_datum_t * " data ", const gnutls_datum_t * " signature ");"
.SH ARGUMENTS
.IP "gnutls_x509_crt_t crt" 12
Holds the certificate to verify with
.IP "gnutls_sign_algorithm_t algo" 12
The signature algorithm used
.IP "unsigned int flags" 12
Zero or an OR list of \fBgnutls_certificate_verify_flags\fP
.IP "const gnutls_datum_t * data" 12
holds the signed data
.IP "const gnutls_datum_t * signature" 12
contains the signature
.SH "DESCRIPTION"
This function will verify the given signed data, using the
parameters from the certificate.
.SH "RETURNS"
In case of a verification failure \fBGNUTLS_E_PK_SIG_VERIFY_FAILED\fP
is returned, \fBGNUTLS_E_EXPIRED\fP or \fBGNUTLS_E_NOT_YET_ACTIVATED\fP on expired
or not yet activated certificate and zero or positive code on success.
Note that since GnuTLS 3.5.6 this function introduces checks in the
end certificate ( \fIcrt\fP ), including time checks and key usage checks.
.SH "SINCE"
3.4.0
.SH "REPORTING BUGS"
Report bugs to <bugs@gnutls.org>.
