Implementations

impl<CIPH: NewBlockCipher + BlockEncrypt + BlockDecrypt + Clone> FF1<CIPH>

pub fn new(key: &[u8], radix: u32) -> Result<Self, ()>

Creates a new FF1 object for the given key and radix.

Returns an error if the given radix is not in [2..2^16].

pub fn encrypt<NS: NumeralString>(&self, tweak: &[u8], x: &NS) -> Result<NS, ()>

Encrypts the given numeral string.

Returns an error if the numeral string is not in the required radix.

pub fn decrypt<NS: NumeralString>(&self, tweak: &[u8], x: &NS) -> Result<NS, ()>

Decrypts the given numeral string.

Returns an error if the numeral string is not in the required radix.
