# ne\_ssl\_trust\_cert(3)

functions to indicate that certificates are trusted

## NAME

ne\_ssl\_trust\_cert, ne\_ssl\_trust\_default\_ca - functions to indicate that certificates are trusted

## SYNOPSIS

```
#include <ne_session.h>
```

**void ne\_ssl\_trust\_cert(ne\_session \****session***, const ne\_ssl\_certificate \****cert***);**

**void ne\_ssl\_trust\_default\_ca(ne\_session \****session***);**

## DESCRIPTION

To indicate that a given certificate is trusted by the user, the certificate object can be passed to **ne\_ssl\_trust\_cert**. The certificate object is duplicated internally and can subsequently be destroyed.

The SSL library in use by neon may include a default set of CA certificates; calling the **ne\_ssl\_trust\_default\_ca** function will indicate that these CAs are trusted by the user.

## EXAMPLES

Load the CA certificate stored in /path/to/cacert.pem:

```
ne_session *sess = ne_session_create(...);
ne_ssl_certificate *cert = ne_ssl_cert_read("/path/to/cacert.pem");
if (cert) {
   ne_ssl_trust_cert(sess, cert);
   ne_ssl_cert_free(cert);
} else {
   printf("Could not load CA cert: %s\n", ne_get_error(sess));
}
```

## HISTORY

**ne\_ssl\_trust\_default\_ca** is not safe to call for non-SSL sessions versions of neon before 0.33.0. In 0.33.0 and later, this function is a no-op for non-SSL sessions.
