Text Encryptor
Encrypt and decrypt text using various cipher algorithms. All processing happens in your browser - your data never leaves your device.
Privacy & Security
All encryption and decryption operations are performed locally in your browser. Your text and keys are never sent to any server. This tool is intended for educational purposes and basic encoding - not for securing sensitive data.
Base64
A standard encoding scheme that represents binary data as ASCII text. Commonly used for data transfer and storage.
ROT13
A simple letter substitution cipher that replaces a letter with the 13th letter after it in the alphabet. Its own inverse.
Caesar Cipher
One of the simplest encryption techniques where each letter is shifted by a fixed number of positions in the alphabet.
XOR Cipher
A simple additive cipher using the XOR operation. When the same key is used for encryption and decryption, it acts as its own inverse.
