How HideText Works: XOR + Base64

HideText uses two simple steps to turn readable text into URL-safe, random-looking links.

XOR — reversible transformation

XOR (exclusive OR) has a useful property: (A XOR B) XOR B = A.

Example:

• Plaintext: HELLO
• Key: 12345
• HELLO XOR 12345 → u8#kP // get ciphertext
• u8#kP XOR 12345 → HELLO // restore plaintext

XOR makes text look random but can be recovered with the same key.

Base64 — make data URL-friendly

The XOR result is arbitrary bytes and may include characters that break URLs (for example a+b/c=d). Base64 (or URL-safe Base64) converts those bytes into URL-safe characters.

Example:

• Raw: a+b/c=d //will break URL
• URL-safe Base64: YS1iL2MrZA //URL-safe
• Link: https://hide-text.com/?c=YS1iL2MrZA

Summary

XOR obscures content; Base64 makes the result safe for URLs. Together they produce many different links that reveal the same original text when the correct key is provided.
