How to use

Choose key size (128/192/256), mode and padding.
Provide a key (raw hex or derived from a passphrase via PBKDF2) and IV where needed.
Encrypt or decrypt and copy the ciphertext.

Why show all parameters?

So output is reproducible and interoperable with other systems — no hidden defaults.

Is a passphrase-derived key secure?

PBKDF2 with a high iteration count is reasonable; a random key is stronger.
