Esse é um algoritmo baseado no conceito da cifra de vigenere https://pt.wikipedia.org/wiki/Cifra_de_Vigen%C3%A8re Ele aplica o conceito em um vetor de char entre os carcteres '0' e 'z' abordando 75 caracteres diferentes Esse algoritmo é a parte prática do projeto de APS do primeiro semestre de 2016 com o tema: AS TÉCNICAS CRIPTOGRÁFICAS, CONCEITOS, USOS E APLICAÇÕES

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.

...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.

it's an Java Desktop application that implements many encryption algorithms. 1-RSA 2-El Gamal 3-Hill 4-Vigenere 5-DSA

For details of this cipher see; http://en.wikipedia.org/wiki/Vigenere_cipher This cipher can be broken by frequency analysis, this is a toy project, and should not be used in situations where security is important.

Textcrypter is an encryption tool using vigenere cipher algorithm. Vigenere use the same key/password to encrypt and decrypt a file (symmetric key cryptosystem). Result of the encryption process is a ciphertext in hexa number.

HcryptoJ (Historical cryptology in Java) is a Java based programming library for implementing and analyzing historical ciphers. HcryptoJ is designed to support research and teaching in historical cryptography and computer science. Licensed under GPL.

a perl script to perform Vigenere (polialphabetic enciphering and deciphering) for teaching classes. Keys are stored in a dedicated file in order to have a one time pad to use for messages exchange.

SLEncrypt is a python module for encryption with 11 ciphers at the moment, including ADFGVX, Autokey, Caesar/ROT13, Vigenere, XOR and a lot more. It contains functions allowing you to easily encrypt/decrypt files. The code is about 95% PEP 8 compilant.

alph implements and analyses historical and traditional c(ai)phers providing a pipe interface in order to encrypt and decrypt block text. The program can be conjuncted with pipes reulting in transparent en-decrypt: Atbash,Caesar,Vigenere,Playfair,Vernam..

Cryptomak contains cipher and tools for encryption utility written in php such as substitution, vigenere, affine, transposition and index of coincidence. It is powered by Phrame platform which implements MVC design and Smarty template engine.
