Modern Symmetric Cipher Lab

Encrypt and decrypt with AES-GCM/CBC/CTR and PBKDF2, with byte-level and process-stage visualization.

Who it helps

Cryptography learners.

A practical use case

Explore authenticated encryption and see how changing a key affects decryption.

Before you rely on the result

Keep keys and salts safely. Educational experiments do not replace a reviewed security protocol.
