# [NAME](#NAME)

gnutls\_certificate\_set\_verify\_limits - API function

# [SYNOPSIS](#SYNOPSIS)

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

**void gnutls\_certificate\_set\_verify\_limits(gnutls\_certificate\_credentials\_t res, unsigned int max\_bits, unsigned int max\_depth);**

# [ARGUMENTS](#ARGUMENTS)

[gnutls\_certificate\_credentials\_t res](#gnutls_certificate_credentials_t)

is a gnutls\_certificate\_credentials type

[unsigned int max\_bits](#unsigned)

is the number of bits of an acceptable certificate (default 8200)

[unsigned int max\_depth](#unsigned~2)

is maximum depth of the verification of a certificate chain (default 5)

# [DESCRIPTION](#DESCRIPTION)

This function will set some upper limits for the default verification function, **gnutls\_certificate\_verify\_peers2()**, to avoid denial of service attacks. You can set them to zero to disable limits.
