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.

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.

The examples below demonstrate the usage with promises. With ecmascript 7, you can await the promises to get the result as in synchronous code. This works for all the code below. To use the await keyword, it must be contained inside an async function.

laravel-optimus - Transform your internal id's to obfuscated integers based on Knuth's integer hash.

•    PHP

Laravel wrapper for the Optimus Library by Jens Segers with multiple connections support. Optimus is a small open-source library that generates short, unique, non-sequential ids from numbers. With this library, you can transform your internal id's to obfuscated integers based on Knuth's integer hash. It is similar to Hashids, but will generate integers instead of random strings. It is also super fast. First, pull in the package through Composer.
