Text Encryption

Encrypt and decrypt text using various methods including Base64, Caesar cipher, and ROT13. Secure your sensitive information.

Encryption Methods

Base64 Encoding

Base64 is a binary-to-text encoding scheme. It's commonly used for encoding data in web applications and email systems. Note: This is encoding, not encryption!

Caesar Cipher

A simple substitution cipher where each letter is shifted by a fixed number of positions in the alphabet. Julius Caesar used this method with a shift of 3.

ROT13

A special case of Caesar cipher with a fixed shift of 13. It's often used in online forums to hide spoilers or offensive content.

Reverse Text

Simply reverses the order of characters in the text. Easy to decode but can be useful for basic obfuscation.

How to Use

  1. Choose Method: Select your preferred encryption method from the dropdown
  2. Set Parameters: For Caesar cipher, set the shift amount (1-25)
  3. Enter Text: Type or paste your text in the input area
  4. Encrypt/Decrypt: Click the appropriate button to process your text
  5. Copy Result: Use the copy button to copy the result to your clipboard

Security Note

Important: These methods are for educational purposes and basic obfuscation only. For real security needs, use proper encryption libraries and strong encryption algorithms like AES.

  • Base64 is encoding, not encryption - anyone can decode it
  • Caesar cipher and ROT13 are easily breakable
  • Never use these methods for sensitive data like passwords or personal information
