GentleGPG II is an easy to use PGP data encryption program. Two or more people can communicate securly using PGP encryption. This program was written with ease of use in mind and is fully portable. GentleGPG II makes encrypting and decrypting your email (or any other) messages easy by enabling you to drag a cursor to Retreive the data you wish to decrypt from another program's window, such as an email client. You can also drag a cursor to Send encrypted data from GentleGPG II to another program. GentleGPG II is very easy to set up, automatically creating your public/secret key. Instructional video: http://youtu.be/cP8kCd8wdZc See Wiki for changes between GentleGPG and GentleGPG II.

A Javascript implementation of the Blowfish Encryption Algorithm described by Bruce Shneier circa 1993. Blowfish is a keyed, symmetric block cipher common in cipher suites and was placed, by Mr. Shneier, in the public domain.

GoFileEncoder is a little file encoder that uses the XOR encryption. It is coded in Golang, and is compiled for several OSs (Windows®, Linux®, and soon macOS®).

A very simple file encryption tool. Release 1 is a text editor that saves encrypted files. Release 1.1 will include the ability to convert any file, even binary, to a GEF (Gulosh Encrypted File). Release 2.0 brings the strong encryption into play.

The hash latch generates keys in a manner similar to how some cryptocurrencies are mined. It takes a string and brute-forces a prefix for it so that the hash of the string with the prefix has a certain number of leading zeroes. But that alone would've been too easy to hack. To prevent an attacker from forging the keys by generating a new prefix: the hash latch doesn't output the keys in the plaintext. Instead, it encrypts the key and outputs the ciphertext. That means that instead of giving you the actual key, it gives you a safe containing the key. This approach allows the hash latch to protect itself from forged keys and also enables you to put the same key into multiple safes without the recipients of these safes knowing they have the same key (even if they compare their ciphertexts). Moreover, the hash latch verifies the integrity of a key after decrypting it (just in case). You can read the tutorial about it on Instructables: https://www.instructables.com/Hash-Latch/

Hemmelig is a privacy-focused secret sharing service that lets users securely share sensitive information like passwords, API keys, private notes, or confidential links using client-side encryption so that the server never sees unencrypted data. It operates with a zero-knowledge architecture: all encryption and decryption happen in the browser, and only encrypted blobs are transmitted to and stored on the server, reducing the risk of leaks or unauthorized access. Users can generate shareable links with optional expiration times, view limits, and password protection to tailor how and when secrets are consumed, and links automatically expire or self-destruct after use to prevent reuse or exposure. The platform supports easy deployment via Docker or hosted options, making it practical for individuals, teams, or enterprises that want to safeguard secrets without relying on third-party storage.

The IEEE 1619 Committee open-source reference implementations of encryption algorithms, plus testing and certification suites, for each encryption algorithm included in the standard.

ImpraStorage provided a private imap access to store large files. Each file stored on the server is split in severals random parts. Each part also contains random noise data (lenght depends on a crypt key) to ensure privacy and exclude easy merge without the corresponding key. An index of files stored is encrypt (with the symmetric-key algorithm Kirmah) and regularly updated. Once decrypt, it permit to perform search on the server and download each part. transfert process is transparent. Just vizualize locally the index of stored files and simply select files to download or upload. ImpraStorage automatically launch the parts to download, then merge parts in the appropriate way to rebuild the original file. Inversely, a file to upload is split (in several parts with addition of noise data), and ImpraStorage randomly upload each parts then update the index.

An encryption library written in C# on .net 2.0, includes SHA1 and MD5 encryption atm. Also includes usercontrols for Visual Studio. Readme can me downloaded separately in the files section.

Java Chaotic Random Number Generator - Inspired by chaos theory, the intent of this generator is to produce unseeded, unpredictable numbers. The numbers will not follow a predictable sequence and will not rely on a pseudorandom algorithm.

JCryptor uses the Caesar-cipher to encrypt keystrokes on-the-fly. It can also be used to decrypt an encrypted text easily. Caesar-cipher is a simple encryption algorithm, developed by Julius Caesar, to encrypt his correspondence with Cicero in the ancient world. Therefore it uses a simple character substitution method to replace a given character by another. A keyshift of thirteen is called ROT13. ROT13 can be decrypted by encrypting it again with ROT13. Even today this simple method is used by authorities to protect documents from unintentional reading. --UPDATE-- [25.01.14] Release 1.0 (final) -- Bugfixes [05.05.12] Release 0.2 -- implements polyalphabeticel substitution

I have packaged the Java encryption library with a wrapper used to make saving and loading files in Java easier. I have also included the source for a command line application to encrypt a String and save it to a text file. The source for AESEncryption was actually written by "erickson" from Stack Overflow. The original post can be found here: http://stackoverflow.com/questions/992019/java-256-bit-aes-password-based-encryption/992413#992413
