CyberChef - The Cyber Swiss Army Knife - a web app for encryption, encoding, compression and data analysis

•    Javascript

CyberChef is a simple, intuitive web app for carrying out all manner of "cyber" operations within a web browser. These operations include simple encoding like XOR or Base64, more complex encryption like AES, DES and Blowfish, creating binary and hexdumps, compression and decompression of data, calculating hashes and checksums, IPv6 and X.509 parsing, changing character encodings, and much more. The tool is designed to enable both technical and non-technical analysts to manipulate data in complex ways without having to deal with complex tools or algorithms. It was conceived, designed, built and incrementally improved by an analyst in their 10% innovation time over several years.

tweetnacl-js - Port of TweetNaCl cryptographic library to JavaScript

•    Javascript

Port of TweetNaCl / NaCl to JavaScript for modern browsers and Node.js. Public domain.The primary goal of this project is to produce a translation of TweetNaCl to JavaScript which is as close as possible to the original C implementation, plus a thin layer of idiomatic high-level API on top of it.

cipherhub - encrypt messages based on ssh public keys with easy import from github

•    Javascript

It can be frustrating and annoying to communicate with somebody using public key cryptography since setting up PGP/GPG is a hassle, particularly managing keyrings and webs of trust.and it will fetch their public keys from github, storing the key locally for next time.

coyim - coyim - a safe and secure chat client

•    Go

CoyIM is a new client for the XMPP protocol. It is built upon https://github.com/agl/xmpp-client and https://github.com/coyim/otr3. It adds a graphical user interface and implies safe and secure options by default. Our ambition is that it should be possible for even the most high-risk people on the planet to safely use CoyIM, without having to make any configuration changes. To do this, CoyIM has OTR enabled and uses Tor by default. Besides that, it will only use the Tor Onion Service for a known server and also uses TLS and TLS certificates to verify the connection - no configuration required. The implementation is written in the Go language, to avoid many common types of vulnerabilities that come from using unsafe languages.

aes-cross - A real cross platform AES encryption-decryption solution

•    Java

Only all these 5 things are exactly the same can the AES encription and decryption be used anywhere. Most language supports ECB,CBC,CFB cipher mode (CBC is used widely), and all key sizes(128 is used widely). But the padding mode is different in different platforms, and it's also effected by cipher mode. You don't need any extra code on these platforms, just make sure using AES/CBC/PKCS5Padding ,and same iv, same key, the encription and decription will cross platforms. There're some platform don't support PKCS5Padding , that's the project to resolve it.
