The krb5_random_confounder() function creates a random value that can be used as a confounder when encrypting data. A confounder is used to initialize the encryption block chaining value so the encrypted result is different each time a data value is encrypted, even when the data value and encryption key are not changed.

Authorities

No authorities are required.

Parameters

context (Input): The Kerberos context.
buffer_size (Input): The size of the output buffer.
output_buffer (Output): The buffer to receive the confounder.

Return Value

If no errors occur, the return value is 0. Otherwise, a Kerberos error code is returned.
