krb5_c_encrypt Encrypt data

krb5_c_enctype_compare Compare two encryption types

krb5_c_encrypt_length -- Get the length of encrypted data 

C Prototype 

krb5_error_code krb5_c_encrypt_length (
        krb5_context            context,
        krb5_enctype            enctype,
        size_t                  inputlen,
        size_t                  *length );

Arguments 

context (input/output)		The context structure.
enctype (input)		The encryption type.
inputlen (input)		The length of the encrypted data to check.
length (output)		The length of the unencrypted data.

Description 

This routine finds the actual (unencrypted) length of data that has been encrypted. Encryption can potentially change the size of the data, so unencrypted and encrypted lengths may be different.

Return Values 

This routine returns the following KRB5 status code:

KRB5_BAD_ENCTYPE

Bad encryption type.
