Limits and behavior

Results are generated in your browser, not uploaded to CraftAI. Inputs are size-limited and validated. Authenticate and decrypt a CraftAI encrypted text envelope. Enter your own input, adjust settings, then process. Inspect and save the generated result. Reset or cancel to clear results. Processing stays on this device. File limit 20 MB; encryption plaintext limit 10 MB. Keep your passphrase safely: encrypted content cannot be recovered without it. Rejects modified ciphertext or the wrong passphrase.

Decrypt encrypted text safely

Decode a compatible AES-GCM text envelope and verify its authentication tag before displaying plaintext.

Can modified ciphertext still be trusted?

No. Authenticated decryption is meant to reject incorrect keys or tampered encrypted data.
