SpritzCipher

Spritz library for Arduino, CSPRNG, cryptographic hash and MAC functions, symmetric-key data encryption, and some general-purpose functions. Spritz is a spongy RC4-like stream cipher and hash function. This library contains a cryptographic pseudo-random number generator, cryptographic hash and message authentication code (MAC) functions, can perform symmetric-key authenticated data encryption, and general-purpose functions for timing-safe comparison and wiping data from memory.
