CraptEV1A restrictively licensed implementation of ciphertext only attacks against crypto1 cipher.
This code was released after piwi's code had reached some maturity. Later aczid also released a brute forcer patch. Their combined code will outperform my original code in almost all cases. You can find the patch by aczid here.
Crapto1A gpl implementation of attacks against the crypto1 cipher which in one way or another rely on known plaintext or the weak nonce generation of the original mifare classic implementations.
