About this tool

Wrong password? You see "decryption failed"

AES-GCM authenticates the ciphertext. If even one byte is wrong — or the password is incorrect — the decrypt operation fails cleanly. There's no partial recovery, no garbled output. This is by design: corrupted or tampered files are rejected, not silently passed through.
