    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 information to another party, you may encrypt it using BitCrypt and publish it as a part of a website. ...

    TTAK.KO-12.0223 Lightweight Encryption Algorithm Tool

    The Lightweight Encryption Algorithm (also known as LEA) is a 128-bit block cipher developed by South Korea in 2013 to provide confidentiality in high-speed environments such as big data and cloud computing, as well as lightweight environments such as IoT devices and mobile devices. LEA is one of the cryptographic algorithms approved by the Korean Cryptographic Module Validation Program (KCMVP) and is the national standard of Republic of Korea (KS X 3246).

    TraySafe

    TraySafe

    Elegant and reliable profile data storage

    ...PIN functionality is included in versions 1.1.0 and above. The serious perk of the app is that all the info is saved as encrypted data in the data.tsf file in the program directory. The simple yet effective encryption algorithm has a password hash, salt key and vigenère cipher key that are changed with every update. The only thing you have to do when updating is to delete the .tsf files and re-enter all your info again so that it can be encrypted using the new parameters. Detailed How-To can be found in the project wiki.

    MOTE CSPRNG & Stream Cipher

    MOTE CSPRNG & Stream Cipher

    A family of small-state CSPRNGs and Stream Ciphers

    MOTE is a fast, small-state, cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. MOTE exhibits uniform distribution, mixes extremely rapidly, has no detected bias, and comes in three variants: MOTE8, with an internal state array of 8+4 32-bit words; MOTE16, with an internal state of 16+4 words; and MOTE32 with a 32+4-word state. The former permit seeding with a key of up to 256 or 512 bits, the latter with a 1024-bit key. Reduced to essentials, MOTE is only...

    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 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, on a key-phrase of any complexity. ...

    Simplest Text Encrypter

    A simple example of polyalphabetic cipher in Java.

    Cryptography fascinates everyone. A variety of encryption techniques and ciphers are used to code important data. A polyalphabetic cipher is one of the simplest cipher one can make. This is a Java program to implement polyalphabetic cipher. [How the cipher encodes?] 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. ...

    MLCrypt

    Simple, lightweight, standalone command-line single file encryption.

    Simple, lightweight, cross-platform (Windows / Linux / ARM6 Linux), cross-arch (x32 / x64), standalone command line file encryption program. GnuPG is probably the best application for cross-platform encryption. However, its usage on Windows PCs may be inconvenient (installation administrator rights; large executable size for perhaps just a one-time file decryption, complicated command-line switches for stronger encryption). NCrypt would fulfill this task, but does not operate on 64-bit...
