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. In this manner, another party can access it without anyone realizing that information is transmitted. The program hides the complexity of its inner workings and is easy to use. It requires only a few steps to perform the task of storing and retrieving text.

(Production / Stable) Command line tool to compute the 64 bit CRC of one or more files.

dk-milter consists of two parts: A milter-based application (dk-filter) which plugs in to Sendmail to provide DomainKeys service, and a library (libdk) which can be used to build DomainKeys-compliant applications or MTAs. See the home page for details.

This application aims to be a simple, small and portable enrypter which encrypts any number of files of any size quickly but securely. It also preserves file extensions which are encrypted with the file and handles ANY file type.

mystic-crypt is designed as a Java library that can be used for simple and complex encryption and decryption. The source code for the library is available under https://github.com/astrapi69/mystic-crypt For demonstration what the library can do there is a graphical client: The source code for the ui is available under https://github.com/astrapi69/mystic-crypt-ui

This software is a simple GUI tool which uses openssl command line utility underneath. It designed to sign any type of files with GOST algorithm (GOST cipher) and will be especially useful for russian ISP's and IT companies which in one way or another have to deal with Roskomnadzor's forbidden sites list to reduce the timewaste while typing in commandline each time you need to sign some file. To use this software you will need to have a ".PEM" file(which exactly used to sign files). If you have your ".PEM" file already - nothing else will be needed. But you can easily make one within this utility. All you need to do this - is a ".PFX"(p12) file. In the openssl folder you'll find an x86 and x64 installation packets of openssl commandline utility which are HIGHLY recommended to use, 'cause this utility was created and tested exactly with those versions of openssl.

sectar: a program that creates encrypted tape archives(tar files), using the AES algorithm Rijndael. Encryption exported under exemption TSU 740.13. Was star, now sectar.

secureDATA is a simple and easy to use encrypted personal information manager. It can store both textual information (passwords, usernames, electronic receipts, etc), and (as of v1.6) files. It uses AES-128 encryption via the Python Cryptography Toolkit.

This tool will allow obfuscation of UNIX scripts listing an interpreter as the first line. It is most useful for distributing functionality in a commercial product or a high user volume environment where you wish to hide proprietary information.

A small, portable utility that can be used to encrypt a text and decrypt a text, using your own passphrase for each of them.

v1pad is a command-line tool that encrypts and decrypts files using one-time-pad encryption. v1pad uses a virtual pad, meaning that the one-time pad is generated dynamically based on user input instead of being stored in a file. The name v1pad is an abbreviation for Virtual One-Time Pad.

C code and Win32 and Win64 DLL to encrypt strings or files with a very fast implementation of AES 256, AES 256 CTR or RC4 encryption methods, full Unicode support through utf-8 encode, support for large files too (above 2 gb).

EverCrack cryptanalysis engine. The goal is cryptanalysis of any class of cipher. The focus now is the kernel - cryptanalysis of unilateral monalpha substitution ciphers extremely quickly, and later, cryptanalysis of complex ciphers for the kernel.

SSH2 client for MacOS before X, based on BetterTelnet, lsh and GUSI.

OhCrypt lets you easily encrypt and decrypt files using some of the most popular algorithms, like AES, Blowfish and Serpent. With OhCrypt, you can secure your data with a password-based encryption algorithm through a clean and simple interface. It demonstrates state of the art of cryptology techniques, such as password hashing and salt. Ohcrypt also features self-extractable and self-destructive encrypted files

PCSecrets is a PC application that holds secret text data - protected by a master password and strong encryption. Use it as a password manager or just somewhere to hold any text data securely in one place. It can hold a second, hidden set of secrets that is undetectable and plausibly deniable. The program is also a PC counterpart of the Secrets for Android app. It uses the same data structure and provides synchronization that allows easy transfer of secrets between the two. For those who find the personal computer environment more comfortable for data entry and editing (i.e. a real keyboard), PCSecrets provides an alternative way to manage your secrets. Sync is also effectively a form of backup. To enable the sync feature with Secrets for Android, you need to install the PCSecrets Sync app, downloadable from SourceForge or Google Play. PCSecrets import plus PCSecrets Sync provides a route to importing secret data into Secrets for Android that would not otherwise be possible.

The In-Browser File Encrypter is a simple web application that enables you to securely encrypt your files directly in your browser using the AES-256 encryption algorithm in CBC mode. Check it out at: https://codepen.io/Northstrix/pen/xxvXvJL and https://northstrix.github.io/In-Browser-File-Encrypter/V1.0/web-app.html GitHub page: https://github.com/Northstrix/In-Browser-File-Encrypter The download shortcut: https://sourceforge.net/projects/in-browser-file-encrypter/files/V1.0%20%28Improved%20UI%29/V1.0%20%28Improved%20UI%29.zip/download Successfully tested in Google Chrome on Windows 11 and Fedora 40.

*PassGuard suite provides a series of application used to manage your numerous passwords in an encrypted file. Additionally, a C++ framework is provided to create password management applications. Plugins system managed different encryption methods.

This release marks the first production-ready publication of 1654, a dependency-free cryptographic vault engine built around a strict vault abstraction and a wide-state cryptographic design. 1654 is not a wrapper around existing crypto libraries. It is a self-contained system whose cryptographic behavior is fully defined within the repository. Key Characteristics Vault-oriented model Encrypted data is treated as a sealed container-safe with explicit operations, not as a password-wrapped file. Dependency-free design The entire cryptographic surface is auditable in-tree. PetoronHash as the cryptographic core All key material derivation, diffusion, and internal transformations are driven by PetoronHash 1024-bit wide internal state The architecture uses a wide internal state to increase diffusion depth and structural safety margins. https://github.com/01alekseev/1654 Petoron | Ivan Alekseev | MIT license
