.SH NAME
gnutls_pkcs7_verify \- API function
.SH SYNOPSIS
.B #include <gnutls/pkcs7.h>
.sp
.BI "int gnutls_pkcs7_verify(gnutls_pkcs7_t " pkcs7 ", gnutls_x509_trust_list_t " tl ", gnutls_typed_vdata_st * " vdata ", unsigned int " vdata_size ", unsigned " idx ", const gnutls_datum_t * " data ", unsigned " flags ");"
.SH ARGUMENTS
.IP "gnutls_pkcs7_t pkcs7" 12
should contain a \fBgnutls_pkcs7_t\fP type
.IP "gnutls_x509_trust_list_t tl" 12
A list of trusted certificates
.IP "gnutls_typed_vdata_st * vdata" 12
an array of typed data
.IP "unsigned int vdata_size" 12
the number of data elements
.IP "unsigned idx" 12
the index of the signature info to check
.IP "const gnutls_datum_t * data" 12
The data to be verified or \fBNULL\fP
.IP "unsigned flags" 12
Zero or an OR list of \fBgnutls_certificate_verify_flags\fP
.SH "DESCRIPTION"
This function will verify the provided data against the signature
present in the SignedData of the PKCS \fB7\fP structure. If the data
provided are NULL then the data in the encapsulatedContent field
will be used instead.
.SH "RETURNS"
On success, \fBGNUTLS_E_SUCCESS\fP (0) is returned, otherwise a
negative error value. A verification error results to a
\fBGNUTLS_E_PK_SIG_VERIFY_FAILED\fP and the lack of encapsulated data
to verify to a \fBGNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE\fP.
