# krb5\_crypto\_destroy(3)

encryption support in krb5

## NAME

**krb5\_crypto\_destroy**, **krb5\_crypto\_init** – encryption support in krb5

## LIBRARY

Kerberos 5 Library (libkrb5, -lkrb5)

## SYNOPSIS

**#include \<krb5.h\>**

*krb5\_error\_code*\

**krb5\_crypto\_init**(*krb5\_context context*, *krb5\_keyblock \*key*, *krb5\_enctype enctype*, *krb5\_crypto \*crypto*);

*krb5\_error\_code*\

**krb5\_crypto\_destroy**(*krb5\_context context*, *krb5\_crypto crypto*);

## DESCRIPTION

Heimdal exports parts of the Kerberos crypto interface for applications.

Each kerberos encrytion/checksum function takes a crypto context.

To setup and destroy crypto contextes there are two functions **krb5\_crypto\_init**() and **krb5\_crypto\_destroy**(). The encryption type to use is taken from the key, but can be overridden with the *enctype*, *parameter*. This can be useful for encryptions types which is compatiable (DES for example).
