gnutls\_cipher\_decrypt3 - API function

# [SYNOPSIS](#SYNOPSIS)

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

**int gnutls\_cipher\_decrypt3(gnutls\_cipher\_hd\_t handle, const void * ctext, size\_t ctext\_len, void * ptext, size\_t * ptext\_len, unsigned flags);**

# [ARGUMENTS](#ARGUMENTS)

[gnutls\_cipher\_hd\_t handle](#gnutls_cipher_hd_t)

is a **gnutls\_cipher\_hd\_t** type

[const void * ctext](#const)

the data to decrypt

[size\_t ctext\_len](#size_t)

the length of data to decrypt

[void * ptext](#void)

the decrypted data

[size\_t * ptext\_len](#size_t~2)

the available length for decrypted data

[unsigned flags](#unsigned)

flags for padding

# [DESCRIPTION](#DESCRIPTION)

This function will decrypt the given data using the algorithm specified by the context. If *flags* is specified, padding for the decrypted data will be removed accordingly and *ptext\_len* will be updated.
