    bitcrypt

    bitcrypt

    BitCrypt is a free ultra-strong encryption that hides text in bitmaps.

    BitCrypt is an elegant encryption that allows for the storage and transmission of information in an undetectable manner. The program processes a user-supplied text encrypting it with the Rijndael cipher and storing it in a user-selected bitmap image. This later step is called steganography, which means "to hide invisibly". If you intend to store sensitive information invisibly, you may encrypt it with BitCrypt and keep it in a picture image. Alternatively, if you intend to pass...

    Ciphey

    Ciphey

    Decrypt encryptions without knowing the key or cipher

    ... to quickly check the ciphertext before working on it yourself, Ciphey is for you. The technical part. Ciphey uses a custom-built artificial intelligence module (AuSearch) with a Cipher Detection Interface to approximate what something is encrypted with. And then a custom-built, customizable natural language processing Language Checker Interface, which can detect when the given text becomes plaintext.

    approach to encryption and decryption involves two strings. The first is an encryption / decryption string which we will allow to be up to 128 lower case alphabetical characters in length. The second string is a line of text from a file that is to be encrypted or decrypted. the basic strategy for encrypting data is based on mapping alphabetical characters to specific values, then doing some simple mathematical operations to create a new value.

    The MOTET Cipher & SE Scrambler

    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...

    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 a cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. It was developed by Bob Jenkins from 1993-1996 and placed in the Public Domain. 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...

    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. ROT13 can be decrypted by encrypting it again with ROT13. Even today this simple method is used...
