    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)...

    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...

    chaOS41

    A cryptocurrency like Bitcoin improved upon with reality binding.

    There is a reason this project holds no code. chaOS41 is a cryptocurrency with reality binding. A given value of money was paid for a surface area the size of a flower pot. It was out of proportion. The chaoOS41 currency corrects that. It binds its value to reality. Its unit value is a ratio between money and land area.. When that ratio normalizes, the currency becomes available to the public. 1 more developer is wanted.

    Visual Cryptography and Bit-Plane Complexity Segmentation in Python

    Hide secret messages in your pictures! Cyberbit lets you transmit a secret message to an intended person in a new manner. The secret message is an 1-bit deep black & white image. The message can contain written text, a drawing, a secret code etc. Using Visual Cryptography the application splits the secret message into two "shadow images" called <<shares>>. Any of the two shares will be embedded into a "normal" image file called by tradition <<vessel>>. You can use a method of hand to...
