KRB5_ENCRYPT(3)

NAME
krb5_decrypt, krb5_decrypt_EncryptedData, krb5_encrypt, krb5_encrypt_EncryptedData - encrypt and decrypt data

LIBRARY
Kerberos 5 Library (libkrb5, -lkrb5)

SYNOPSIS
#include <krb5.h>
krb5_error_code
krb5_encrypt(krb5_context context, krb5_crypto crypto, unsigned usage, void *data, size_t len, krb5_data *result);
krb5_error_code
krb5_encrypt_EncryptedData(krb5_context context, krb5_crypto crypto, unsigned usage, void *data, size_t len, int kvno, EncryptedData *result);
krb5_error_code
krb5_decrypt(krb5_context context, krb5_crypto crypto, unsigned usage, void *data, size_t len, krb5_data *result);
krb5_error_code
krb5_decrypt_EncryptedData(krb5_context context, krb5_crypto crypto, unsigned usage, EncryptedData *e, krb5_data *result);

DESCRIPTION
These functions are used to encrypt and decrypt data.

krb5_encrypt() puts the encrypted version of data (of size len) in result. If the encryption type supports using derived keys, usage should be the appropriate key-usage. krb5_encrypt_EncryptedData() does the same as krb5_encrypt(), but it puts the encrypted data in a EncryptedData structure instead. If kvno is not zero, it will be put in the kvno field in the EncryptedData.

krb5_decrypt(), and krb5_decrypt_EncryptedData() works similarly.
