The objective is to demonstrate character/ symbol frequency distribution analysis (reference to the English language) on 2 vintage ciphers, namely Caesar cipher (a mono-alphabetic substitution cipher) and the Vigenere cipher (a poly-alphabetic substitution cipher).
Under the symbol frequency distribution analysis, the statistical characteristic of the language is still observable from the cipher text from the Caesar cipher, this...
this software use for counting the alphabetic in text file(file.txt).
it can use for affine cipher attack cause this software can now the high distribution a alphabetic
Some flexible substitution cryptogram encryption/decryption tools and a cipher generator.
File encryption/decryption using stream cipher.
It can encrypt/decrypt any type of file.
Given a message encoded with a shift/rotation cipher, such as rot13, this recipe recovers the most probable plain text for the message. It does this by using statistics of bigram (2-character sequence) counts from a sample of text.
A 64-bit private-key block cipher, similar to DES.
A block cipher for the clipper chip program. 64bit blocksize, 80bit keysize. This implementation was developed totally outside of the USA and so it is free from export restrictions.
This program interactively lets you encrypt and decrypt text as well as text files using a key system as well as a cipher.
This function uses frequency analysis to attack and decode messages
encoded using a /substitution cipher/ which exchanges each letter of the
alphabet for another. Unlike the famous "Caesar Shift" cipher, which
The code generates binary sequence of a given length and then writes it to a .txt file. the sequence generated is random in nature and this cipher was used in GSM for 2 decades
softerGLOSSARY is an easy to install, easy to configure, easy to use Glossary for use on any website.
It features full-text searching with results hi-liting, as well as alphabetic filtering. The current version is completely free to...
The Rot13 Encoder/Decoder plugin allows bloggers and commenters to "encrypt" parts of their writing output with the ROT13 cipher in order to conceal media-related spoilers, punchlines, solutions, or sensitive topics from other readers...
JEnigma is a java API to implement the Enigma cipher, as used by the Enigma encryption machine.
TextConverter is a graphical text editor allowing the user to encrypt/decrypt the textual contents displayed on the screen using a 128-bit AES (Advanced Encryption Standard) cipher.
Generate a number output with leading zeros in a defined range and cipher count. Useful for shell developers for example to create directories or to mirror websites.
The Alphabetical Navigation Bar Java Display Tag Library, <nav:alphanavbar:*>, creates an alphabetic navigation bar, by slicing and dicing string data stored in a java.util.List object into 26 alphabetically sub list.
This component is based on the DEC component by Hagen Reddmann that is also freeware. aspEasyCrypt allows you to hash, cipher and make checksum on strings and files. With this component you can make strong security pages, sign page or messages,...
DataEntry Validator is a COM based component that allows you to Validate your data entry and restrict it to predefined type (Numeric - Alphabetic - AlphaNumeric - Date- Decimal) or your defined.
HsCipherSDK is an Encryption Library providing an API to a suite of symmetric key cryptographic algorithms and one way hash digital signature algorithms. The library includes the following block and stream cipher modules:
Aztec Code is a high density 2 dimensional matrix style bar code symbology that can encode up to 3832 numeric or 3067 alphabetic characters or 1914 bytes of data. The symbol is built on a square grid with a bulls-eye pattern at its center. Data is...
