# [NAME](#NAME)

gnutls\_x509\_trust\_list\_verify\_named\_crt - API function

# [SYNOPSIS](#SYNOPSIS)

**#include <gnutls/x509.h>**

**int gnutls\_x509\_trust\_list\_verify\_named\_crt(gnutls\_x509\_trust\_list\_t list, gnutls\_x509\_crt\_t cert, const void * name, size\_t name\_size, unsigned int flags, unsigned int * voutput, gnutls\_verify\_output\_function func);**

# [ARGUMENTS](#ARGUMENTS)

[gnutls\_x509\_trust\_list\_t list](#gnutls_x509_trust_list_t)

The list

[gnutls\_x509\_crt\_t cert](#gnutls_x509_crt_t)

is the certificate to be verified

[const void * name](#const)

is the certificate's name

[size\_t name\_size](#size_t)

is the certificate's name size

[unsigned int flags](#unsigned)

Flags that may be used to change the verification algorithm. Use OR of the gnutls\_certificate\_verify\_flags enumerations.

[unsigned int * voutput](#unsigned~2)

will hold the certificate verification output.

[gnutls\_verify\_output\_function func](#gnutls_verify_output_function)

If non-null will be called on each chain element verification with the output.

# [DESCRIPTION](#DESCRIPTION)

This function will try to find a certificate that is associated with the provided name --see **gnutls\_x509\_trust\_list\_add\_named\_crt()**. If a match is found the certificate is considered valid. In addition to that this function will also check CRLs. The *voutput* parameter will hold an OR'ed sequence of **gnutls\_certificate\_status\_t** flags.

Additionally a certificate verification profile can be specified from the ones in **gnutls\_certificate\_verification\_profiles\_t** by ORing the result of **GNUTLS\_PROFILE\_TO\_VFLAGS()** to the verification flags.

# [RETURNS](#RETURNS)

On success, **GNUTLS\_E\_SUCCESS** (0) is returned, otherwise a negative error value.

# [SINCE](#SINCE)

3.0.0
