Remarks

Parameterised Skein can be used for:

• MAC generation, by providing a key.
• Randomised hashing, by providing a nonce.
• A hash function for digital signatures, associating a public key with the message digest.
• A key derivation function, by providing a key identifier.
• Personalised hashing, by providing a recommended format or arbitrary personalisation string.
