    d-crypt

    Tweakable 256-bit symmetrical block cipher.

    D-crypt is an symmetrical block cipher operating on 256bit blocks with an key of the same length. The cipher takes 3 inputs: the data to encrypt, the symmetric key and a tweak consisting in a array of 16 integers representing each one of eleven possible keyaddition algorithms. Features a similar structure as AES (uses simpler versions of ShiftRows, MixColumns) and uses AES SBOX. It is an SP network. The Key Schedule is a different from AES's, however the Expansion is partially inspired in...

    SES Super-Encypherment Scrambler

    SES Super-Encypherment Scrambler

    SES brings back the uncrackable onetime pad, with a digital twist.

    SES brings back the uncrackable onetime pad, with a digital twist. It is well known that a random key of message-length is the only provably unbreakable cipher. SES uses cryptographic strength pseudo-random keys of message-length for its many encipherments, in addition to offering true one-time pad capability for the intrepid. SES is built on ISAAC, Bob Jenkins' unbroken CSPRNG, a fast and simple stream cipher placed in the Public Domain in 1996. SES now gives you the ability to...

    ISC - The ISAAC Stream Cipher

    ISC - The ISAAC Stream Cipher

    ISC lets you encrypt & decrypt text and files of any type up to 4GB

    ...ISAAC is fast - especially when optimised - and portable to most architectures in nearly all programming and scripting languages. After more than 20 years of existence ISAAC has not been broken, and the little program you have here allows you to use it to encrypt and decrypt text of arbitrary length, files of any type, on a key-phrase of any complexity. ISC is a symmetric key encryption system, which means that both the sender and recipient of a message must possess the key.

    JCryptor

    JCryptor is an encrypting tool based on the Caesar-cipher.

    JCryptor uses the Caesar-cipher to encrypt keystrokes on-the-fly. It can also be used to decrypt an encrypted text easily. 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.
