What is Text Encryptor — Caesar, Vigenère, ROT13, Atbash Free?
A text encryptor applies classical cipher algorithms to encode and decode text messages. Supported ciphers include Caesar cipher (shift by N), Vigenère cipher (keyword-based), ROT13 (shift by 13), Atbash (reverse alphabet), and Base64 encoding. These are educational encryption tools — not suitable for securing sensitive data, but excellent for learning how encryption works and for simple obfuscation.
