encapsulates secure crypto algorithms for easy use
This library exposes security functionality to the programmer, such as random number generation, hashing, salted hashing, message authentication code, symmetric encryption, asymmetric encryption, hybrid encryption, digital signature and in-memory protection. The library is accompanied by a sophisticated reference implementation, that demonstrates how to make use of the CryptoLibrary.
This is the fastest encryption tool for Windows, it allows you to encrypt whole hard drives or incredibile large and multitude of files in the matter of seconds.
Now you can quickly protect your files and folders with password and prevent anyone from opening them.
Source Code available here: https://asmodatfolderlocker.codeplex.com/
Project is entirely opensource, you can change it if you wish to what suits your purposes best, or send me email to request a new feature. All ideas and propositions are welcome.
Requirements:
-Windows 7 or later
...You can also save your converted text to a file or open a converted text file to decrypt the message, and perform basic arithmetic in binary.
The git repo for the C# code is located at: https://github.com/m1r4g3/BinaryCrypt-.Net
Decrypt messages encrypted with a substitution cipher
...
• Easy location of corresponding characters in the ciphertext and the substituted text
by selection.
• Fast frequency analysis for single letters, bigrams, trigrams and quadgrams (more
N -grams can be made available by adding a single line of code).
• Showing the most common letters (bi-/trigrams) in the ciphertext compared to the
most common letters (bi-/trigrams) in the British English language.
• Easy assignment and change of the substitution letters.
• Auto assignment of the 10 first letters.

A file encryption program created specifically for the soul purpose of security. This program is completely free and open-source, but the source code may only be distributed by Zinga, unless authorized.
Power Hasher is a program that allow you to get the hash code of multiple files at once, and export the results to a file, making easy for this file to be imported and the files checked. Currently it supports MD5, SHA1, SHA256, SHA384 and SHA512.
This library provides two operations: one to wrap key data, and another to unwrap the key data. This code also includes a fairly comprehensive unit test library which ensures the implementation is verified against the vectors provided in RFC 3394.
