About this tool
Encrypt UTF-8 text with password-derived AES-256-GCM, or decrypt this tool’s envelope.
Common uses
- Encrypt UTF-8 text with password-derived AES-256-GCM, or decrypt this tool’s envelope.
- Choose Encrypt, enter text and a password, then copy the complete xt-aes-gcm-v1 output.
How to use it
- 1.Choose Encrypt, enter text and a password, then copy the complete xt-aes-gcm-v1 output.
- 2.To decrypt, paste that complete envelope and use the same password.
Limits and notes
- Uses PBKDF2-SHA256 with 150000 iterations, a random 16-byte salt and 12-byte IV. Arbitrary raw AES ciphertext is not accepted; wrong passwords or changed data fail authentication.
