NAME    [Toc]    [Back]

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

LIBRARY    [Toc]    [Back]

     Kerberos 5 Library (libkrb5, -lkrb5)

SYNOPSIS    [Toc]    [Back]

     #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    [Toc]    [Back]

     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.
