XOR Encoder with Cipher Feedback

Created

Description

Dword XOR encoder with cipher feedback for RISC-V 32-bit
(Little Endian). Each dword is XORed with the previous encoded
dword rather than a static key, creating a chained dependency
that makes the output more resistant to frequency analysis. The
first dword is XORed with the key to bootstrap the chain.
