How does the file decryptor verify file integrity?

AES-GCM includes an embedded 128-bit authentication seal. If the file has been corrupted, modified, or the password is wrong, decryption immediately halts.

Does the decrypted file retain its original filename and extension?

Yes. The Qwertygen container securely encapsulates the original file metadata and restores its exact name and mime type upon successful decryption.

Is there any file size limit for decryption?

Decryption is constrained only by available browser memory. Most desktop browsers can easily process files up to several hundred megabytes in local RAM.
