Open Source C# Cryptography Software - Page 6

Stegano.Net is free Steganography Tool for Windows. It hides texts/files/data in images. The secret data can be unveiled from the Images afterwards.

The provided program helps the user with the deciphering of a substitution cipher with the 26 letter alphabet by providing the following features • Dynamic entering of ciphertext. Ciphertext can be modified at any point of the process. • 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.

This substitution cipher toolkit enables you to en- and decrypt texts with substitution cipher, to gather language statistics of a specific language and to crack encrypted texts both manually and automatically. All functions can be accessed via an easy-to-use graphical user interface.

Thoughts is an electronic journal/diary program based on the .NET framework (C#). It allows entries to be saved locally and/or remotely via web service or directly to a database. The entries can also be encrypted prior to saving.

If you're like me and you don't think your passwords are safe as cookies in your browser or any other place for that matter then this is the right app for you. TraySafe's minimalist UI is designed to be shown only in your system tray icons. With it you can copy both your username/email and password using only your left and right mouse buttons. The scroll button is used to delete items from the menu. 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.

Vernash: Stream cipher based on the Vernam cipher and Variable-Length Hashes

This command-line utility produces a report of file information including version information where available. The reports can be useful for release information, manifests, and integrity verification.

Vijner 974 E-Sys (2048 bits and unlimited encryption). Enables easy (un-)encryption from text input or .txt file, and to (un-)encrypt raw files, with Vigenère Algorithm + unlimited encryption keys. Simple and powerful. Adapt to fit your needs.

Waste.NET is a complete rewrite of the now defunct W.A.S.T.E. project. It aims to become a highly secure file sharing application, as well as a secure chat/VOIP platform.

Waste.net is a .NET-driven application geared towards providing a secure online encrypted file-sharing service. This is a purely managed .NET 2.0 port of the original Waste client/server.

You can calculating md5 hashsums, comparing files and hashsums in pairs. If you have backups of one file and you have a md5 hashsum, you can compare your backups against this md5 hashsum. Calculating SHA256 hashes too. This repository will no longer updated! Please take a look at this url: https://github.com/tualatin/winmd5checksum
