Frequently Asked Questions
Is XOR encryption secure?
No. XOR with a repeating key is easily broken. It is useful for obfuscation, not security.
Can the same function encode and decode?
Yes. XOR is its own inverse. Applying the same key to encoded text produces the original text.
What key formats are supported?
Keys can be entered as plain text or hexadecimal strings.
What encoding tools are available?
We offer Base64 encoder/decoder, URL encoder/decoder, hash generator (MD5, SHA), XOR encoder, ROT13, Caesar cipher, and more.
Are these encoding tools free?
Yes. Every encoding tool is free and requires no account, installation, or usage limits.
Is my data secure during encoding?
All encoding and decoding happens in your browser. No data is ever sent to external servers, making it safe for sensitive information.
Do the tools support Unicode?
Yes. All tools handle UTF-8 encoded text including non-ASCII characters, emoji, and international text correctly.
Privacy & Security
All processing happens entirely in your browser using client-side JavaScript. Your files and text are not uploaded to Tool-web's server.
