# gnutls\_x509\_trust\_list\_verify\_named\_crt(3)

API function

## NAME

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

## 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

- gnutls\_x509\_trust\_list\_t list

  The list

- gnutls\_x509\_crt\_t cert

  is the certificate to be verified

- const void \* name

  is the certificate's name

- size\_t name\_size

  is the certificate's name size

- unsigned int flags

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

- unsigned int \* voutput

  will hold the certificate verification output.

- gnutls\_verify\_output\_function func

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

## 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

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

## SINCE

3\.0.0
