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

API function

## NAME

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

## SYNOPSIS

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

**int gnutls\_x509\_trust\_list\_add\_named\_crt(gnutls\_x509\_trust\_list\_t** *list***, gnutls\_x509\_crt\_t** *cert***, const void \*** *name***, size\_t** *name\_size***, unsigned int** *flags***);**

## ARGUMENTS

- gnutls\_x509\_trust\_list\_t list

  The list

- gnutls\_x509\_crt\_t cert

  A certificate

- const void \* name

  An identifier for the certificate

- size\_t name\_size

  The size of the identifier

- unsigned int flags

  should be 0.

## DESCRIPTION

This function will add the given certificate to the trusted list and associate it with a name. The certificate will not be be used for verification with **gnutls\_x509\_trust\_list\_verify\_crt()** but with **gnutls\_x509\_trust\_list\_verify\_named\_crt()** or **gnutls\_x509\_trust\_list\_verify\_crt2()** - the latter only since GnuTLS 3.4.0 and if a hostname is provided.

In principle this function can be used to set individual "server" certificates that are trusted by the user for that specific server but for no other purposes.

The certificate  *cert* must not be deinitialized during the lifetime of the  *list* .

## RETURNS

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

## SINCE

3\.0.0
