What aes-gcm encrypt does

Random 16-byte salt and 12-byte IV. Losing the password loses the plaintext. This is not a hash reverser.

How this page works

All options on the form are sent into the local engine. AES-GCM with PBKDF2-SHA-256 (210000 iterations). Blob prefix cznull1. Results never leave this device to be computed.

Questions

Does this page upload what I type?
No. The work runs in the page you opened. CZNull does not receive the input.
Can this decrypt an MD5 or SHA digest?
No. Hashes are not this ciphertext format.
What is cznull1.?
A CZNull prefix, then Base64 of 16-byte salt, 12-byte IV, and AES-256-GCM ciphertext. Other tools will not open it unless they implement the same packing.
Lost password?
The plaintext cannot be recovered here.
