Security Decoder
Analyze and decode obfuscated payloads. Supports sequential decoding stages to peel back multiple layers of encoding.
Pro Tip: Sequential decoding allows you to see the payload at different levels of de-obfuscation. If a stage fails (e.g., input isn't valid Base64), that stage and subsequent stages will display the raw input from the previous step.

Encoding vs. Encryption
Encoding (like Base64 or Hex) is a way to transform data into a different format using a publicly known scheme. It is not a security measure on its own, as anyone can reverse it. Encryption, on the other hand, requires a secret key to decode.
Why do we use these encodings?
- Base64: Used to represent binary data (like images or encrypted blobs) in a safe ASCII format for transmission via email or HTTP.
- URL Encoding: Used to safely include reserved characters (like spaces or slashes) in a URL.
- Hex (Hexadecimal): A base-16 representation of binary data, often used to display memory contents or cryptographic keys.
Multi-stage Decoding
In security analysis, payloads are often wrapped in multiple layers (e.g., a Base64-encoded string that contains a URL-encoded script). This tool allows you to "peel back" these layers by applying decoders in a sequence.
Privacy First
Just like our other tools, all decoding happens locally in your browser. Your sensitive payloads never leave your machine.
