Cryptanalysis recopilation

This is a big recopilation of cryptanalysis tools/books/papers and crypto challenges/solutions (CTFs). I'm planning to update it periodically. If you know some good information in this direction please ping me ;)

• https://sourceforge.net/projects/msieve/

• https://code.google.com/archive/p/hash-identifier/source

• Nonce-Disrespecting Adversaries: Practical Forgery Attacks on GCM in TLS https://github.com/nonce-disrespect/nonce-disrespect

• PkCrack - Breaking PkZip-encryption https://www.unix-ag.uni-kl.de/~conrad/krypto/pkcrack.html
