Create a crypto context used for all encryption and signature operation. 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).
To free the crypto context, use krb5_crypto_destroy().
Parameters:
context Kerberos context
key the key block information with all key data
etype the encryption type
crypto the resulting crypto context
Returns:
Return an error code or 0.
Inline decrypt a Kerberos message.
Parameters:
Returns:
1. KRB5_CRYPTO_TYPE_HEADER 2. one KRB5_CRYPTO_TYPE_DATA and array [0,...] of KRB5_CRYPTO_TYPE_SIGN_ONLY in any order, however the receiver have to aware of the order. KRB5_CRYPTO_TYPE_SIGN_ONLY is commonly used unencrypoted protocol headers and trailers. The output data will be of same size as the input data or shorter.
Inline encrypt a kerberos message
