Hey Product Hunt! 👋 I'm the maker of Toolgio, and I built this AES-256 Decryption Tool because I kept running into the same frustration — most online decryption tools either send your data to a server (huge privacy risk!) or only support one mode like CBC, leaving developers stuck. So I built something better: 🔐 100% client-side — your data NEVER leaves your browser ⚡ Supports GCM, CBC, ECB & CTR modes 🔑 PBKDF2 password-based key derivation 📁 File drag-and-drop decryption 🔄 Base64 & hex input/output support 🆓 Completely free — no signup, no limits I originally built this for my own projects but realized developers, security researchers, and CTF players would find it just as useful. So I launched it publicly on Toolgio — my platform for free online developer tools. I'd love your feedback! What features would make this even more useful for you? 🙏 Try it free → toolgio.com/aes-256-decryption-online-tool
