Decrypt File Online Free

Decrypt .stnenc files created with the Encrypt File tool.

verified_user Your files are processed only as needed and are not stored after the tool finishes.
Decrypt files created with the SimpleToolsNow Encrypt File tool. Upload the .stnenc file, enter the original password, and download the recovered file. The encrypted file stores the salt, nonce, and ciphertext needed for AES-GCM decryption, but never stores the password. If the password is wrong or the encrypted bytes were modified, authentication fails and no decrypted file is returned. This makes it useful for recovering protected files while preserving integrity checks.

Frequently Asked Questions

Can you recover a forgotten password? expand_more
No. The password is required to decrypt the file.
What if the .stnenc file was modified? expand_more
AES-GCM authentication will detect the modification and decryption will fail, protecting you from corrupted or tampered files.
