Security and Accuracy Disclaimer

Classical ciphers provided on this site — including Caesar cipher, Vigenère cipher, substitution cipher, ROT13, Rail Fence, Playfair, and others — are not cryptographically secureby modern standards. They were designed centuries before modern computing and can be broken trivially with today's tools.

Do not use classical ciphers to protect sensitive, confidential, or personal information. For real security needs, use modern encryption standards such as AES-256, RSA, or TLS. SolveCipher.com is not responsible for any loss, damage, or security breach resulting from reliance on our cipher tools for security purposes.

While we strive for accuracy, cipher outputs are provided as a reference and educational tool. We make no guarantee that outputs are correct in all edge cases. Always verify critical results independently.
