Open Source JavaScript Cryptography Software

EJBCA is an enterprise class PKI Certificate Authority built on JEE technology. It is a robust, high performance, platform independent, flexible, and component based CA to be used standalone or integrated in other JEE applications.

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.

Clipperz is a web based password manager. Local encryption within the browser guarantees that no one except you can read your data. A true zero-knowledge (or host-proof) web app!

Codegroup is a Java application that will allow one to convert binary (or text) computer files in to 5 letter codegroups for transmission over email, landline telephones, radioteletype or Morse Code. Codegroup has internal error correction & limited cryptography capabilities.
