@gykh/vigenere-cipher is an educational and utility library implementing the classical Vigenère substitution cipher.
Warning
The Vigenère cipher is a 16th-century polyalphabetic substitution cipher and is not cryptographically secure against modern cryptanalysis. It should not be used to protect sensitive data or passwords in production systems.
If you discover a vulnerability or denial-of-service issue in the implementation (e.g. infinite loop, memory exhaustion, unexpected crash), please report it responsibly by contacting:
