Vigenère
A powerful tool for cracking the Vigenère cipher
Vigenère is a program for encrypting and decrypting text using the Vigenère cipher. Built-in cryptanalysis tools make it possible to crack the cipher without needing the key — or even knowing its length. -

The MOTET Cipher & SE Scrambler
A tiny, fast encryption tool in C
MOTET is a tiny, fast super-encipherment application written in C, featuring the new CSPRNG/stream ciphers MOTE and BEDBUG in each of their three variants, as well as the "gold standard" among ciphers, ISAAC. MOTET brings multiple levels of encryption, including a ciphertext-hash, a Vigenere mixing function, a choice of Caesar MOD or Caesar MIX ciphering on the primary key-stream, plus a deeply scrambled "outer shell" as a final super-encryption stage. A unique nonce IV guarantees that each ciphertext will differ radically from every other, even on the same message and identical key. -

SES Super-Encypherment Scrambler
SES brings back the uncrackable onetime pad, with a digital twist.
...To achieve complete one-on-one privacy, SES traverses several levels en route to its output. The more words in your key-phrase, the more layers of encipherment SES applies. It is part Vigenere, part onetime pad, part cryptographic hash, not to mention the essential scrambler element, each component driven by ISAAC, with all key-derivation and stretching relying on Keccak in 512-bit configuration. -

Simple Cipher Decoder
Decrypts and encrypts substitution, transposition and vigenere ciphers
...This is a series of three simple programs that will allow you to easily encrypt and decrypt text using any combination of substitutions, transpositions, vigenere ciphers or caesar shifts. The programs will not completely solve the ciphers for you haowever they will make it very clear to see how to solve them and ensure that there is no need for tedious manual work. -

Vigenere Dictionary Attack
Vigenere brute force / dictionary cracking tool
This is a tool that uses a combination between a brute force and dictionary attack on a Vigenere cipher. At present, keys are generated using brute force (will soon try passwords generated from a dictionary first). Each key is then used to decode the encoded message input. The output is analysed and then put into a ranking table. Outputs will be ranked on a variety of factors (at present, only number of dictionary words in output are counted). -

CaeserCipher
Playing with scripting basic crypto concepts.
It's Vigenere and Caeser implementation, it is a basic implementation of these classical crypto ciphers. When I was implementing, I was trying to add blocks in a linear way but was not able implement a good logic. Have a look inside the code. And let me know, if you saw any defects in the code.
