...Caesar-cipher is a simple encryption algorithm, developed by Julius Caesar, to encrypt his correspondence with Cicero in the ancient world. Therefore it uses a simple character substitution method to replace a given character by another. A keyshift of thirteen is called ROT13. ROT13 can be decrypted by encrypting it again with ROT13. Even today this simple method is used by authorities to protect documents from unintentional reading. --UPDATE-- [25.01.14] Release 1.0 (final) -- Bugfixes [05.05.12] Release 0.2 -- implements polyalphabeticel substitution

...Input Data: helloaf Key: love l - 12th letter in Alphabet o - 15th letter in Alphabet v - 22nd letter in Alphabet e - 5th letter in Alphabet Now: h(l) e(o) l(v) l(e) o(l) a(o) f(v) Further: h(+12) e(+15) l(+22) l(+5) o(+12) a(+15) f(+22) where +(number) meaning shifting the character forward by the respective number of places. So the result comes out to be: tthqapb and the data is encrypted.

This is a simple but sophisticated open source password recovery tool for M$ Windows, it can effectively 'crack' any password protected archive that can be decompressed by 7zip given enough time and resources. It can also bruteforce MD2, MD5, SHA-1 and SHA-2 hashes (SHA-256, SHA-384, SHA-512), CRC16, CRC32, CRC64 and Adler32 hashed passwords for both Windows, and Linux. It requires java 7u4 and above, and 7-zip v9.20 and up for archive recovery. Keeping these above applications up to date...
