About XOR
XOR the input with the given key. e.g. fe023da5 Options Null preserving: If the current byte is 0x00 or the same as the key, skip it. Scheme:Standard - key is unchanged after each round Input differential - key is set to the value of the previous unprocessed byte Output differential - key is set to the value of the previous processed byte Cascade - key is set to the input byte shifted by one
Input: binary bytes (text input uses UTF-8; a file retains its original bytes). Output: binary bytes.

Parameters
| Parameter | Default value | Input and choices |
|---|---|---|
| Key | {"option":"Hex","string":""} | Key/text encoding: Hex, Decimal, Binary, Base64, UTF8, Latin1 |
| Scheme | Standard | Standard, Input differential, Output differential, Cascade |
| Null preserving | false | On or off |
Before interpreting the result
Use the exact key encoding, mode, padding and IV expected by the source system. Historical ciphers are useful for learning and analysis. Encoding alone provides no confidentiality.
How to use this page
- Paste your input or open a local file.
- Adjust tool options if needed, then choose Run tool.
- Copy the result or download the original output bytes.
Inputs and results are not added to the public catalogue or saved in the URL. Processing happens in your browser; HTTP Request and DNS over HTTPS send the requests you explicitly run. Files up to 128 MiB can be opened; decompression and image tools may have smaller processing limits. Large results have a shortened preview. Text and HTML downloads use UTF-8; binary downloads preserve output bytes. Pasted text follows browser newline handling; open a file when exact input bytes matter.
