[Wayback/Archive.is] CyberChef:
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 [Wayback/Archive.is] Solve Crypto with Force! needs to run without most script blockers, so best run it in an anonymous/private browser window.
Source code for SCWF is at [Wayback/Archive.is] DaWouw/SCWF: CTF tool for identifying, brute forcing and decoding encryption schemes in an automated way.
