Open Source JavaScript Encryption Software

cadenas (French for "padlock") encrypts and decrypts a file with a password, right in your browser. No file and no password is ever sent over the Internet: the page is technically not allowed to open any network connection (Content Security Policy connect-src 'none'), and it works offline once installed. It uses Argon2id and XChaCha20-Poly1305, detects any change to an encrypted file, and can read and write the age format, so files stay readable with other tools. The same tool comes as a command line for Windows, macOS and Linux, a Docker image you can self-host, and a JavaScript library. cadenas is free software (MIT) with a documented file format. It has not had an independent security audit yet; the threat model and format are public for review.

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.

AresCode2008 is system to crypt files. System is used new cryptography algorithm.

ClearPass (formerly BlowPass) is web based password storage system that uses the Blowfish algorithm and a Host-Proof design pattern.

Enigma encrypts texts (PINs, Passwords, Messages, etc.) of any kind and is available for any OS, because it's just an HTML-Webpage with JavaScript in the back. So you can share secrets with friends on any device which has a HTML-Browser. On my Homepage you can find out how to use file-encryption.

Enigma GPG Community allows you to encrypt / sign text and attachments using plugins in browsers, to send encrypted information via any Internet application that can only be understood by the intended recipient ensuring the authenticity, privacy and confidentiality of messages between the sender and receiver . Note the utility that can achieve this project because it aims to meet the global need for privacy on the web. Also applies to any web application that allows text input by the user such as social networks, blogs, forums, etc. Very easy in three steps: Send Messages: 1 - Write a messages 2 - With the right mouse button, select enigma cipher 3 - Send the encrypted message Recieve Messages: 1 - Select the message 2 - With the right mouse button, select enigma decrypt Support Tickets: https://sourceforge.net/p/enigmagpg/tickets/

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.

JSRSA is a Javascript/PHP implementation of RSA algorithm which help you to simulate SSL-Like secure data transmission over the net as easy as possible !

The Stanford Javascript Crypto Library is a project by the Stanford Computer Security Lab to build a secure, powerful, fast, small, easy-to-use, cross-browser library for cryptography in Javascript. SJCL is small but powerful. The minified version of the library is under 6.4KB compressed, and yet it posts impressive speed results. SJCL is secure. It uses the industry-standard AES algorithm at 128, 192 or 256 bits; the SHA256 hash function; the HMAC authentication code; the PBKDF2 password strengthener; and the CCM and OCB authenticated-encryption modes. Just as importantly, the default parameters are sensible: SJCL strengthens your passwords by a factor of 1000 and salts them to protect against rainbow tables, and it authenticates every message it sends to prevent it from being modified. We believe that SJCL provides the best security which is practically available in Javascript.
