Decoder
What is hiding in this string?
Paste an odd-looking string. We try the common encodings, peel layers one after another, and let you inspect the raw bytes.
Runs only in your browser. What you paste or load here is never uploaded, saved, or sent anywhere. This page cannot make network requests at all, and it uses no cookies or storage. Reloading or closing the tab clears everything.
Files up to 20 MB are read locally and never uploaded. Be careful with real malware: this tool only reads bytes and never runs anything, but handle samples in a safe environment.
XOR tester
Some malware and obfuscated data is scrambled with a repeating key. Try every one-byte key, or enter your own key.
