ToolsFx is a cross-platform desktop cryptography toolbox built with Kotlin. It bundles encoding/decoding, hash and MAC computation, symmetric and asymmetric encryption, digital signatures, big-number math, compression, QR codes, and CTF helper utilities in one GUI app.

Use cases

• encode and decode base64, base32, url, unicode and other encodings
• compute md5, sha, sm3 and other hashes of files or text
• encrypt and decrypt data with AES, DES, RSA and other ciphers
• generate and verify digital signatures and HMACs
• solve CTF crypto and encoding challenges
• generate QR codes and compress files
• perform big integer arithmetic

When to choose

• you want an offline GUI Swiss-army knife for crypto and encoding tasks
• you regularly work with CTF challenges involving encodings and hashes
• you need many cipher, hash, and MAC algorithms in one tool

When to avoid

• you need a programmatic crypto library to embed in your own code
• you require audited, production-grade cryptographic implementations
• you only need a CLI for scripted crypto operations
