Description

Describe the bug
I encrypted a 2 MB file with amaze file manager uploaded it to the cloud(google drive) for later use. Downloaded and I can't decrypt it anymore. The file ends up creating 0 bytes file . I don't know if its the filename or extensions bcs I changed them several times. Later changed it to .aes to decrypt and it didn't decrypt. And I'm sure I gave the correct password. Also I couldn't decrypt the file using the apps that are recommended on AESCrypts website.

Expected behavior
Encrypt and decrypt successfully.

Smartphone (please complete the following information):

  • OS: Android 9
  • Rooted: No
  • Version: 3.7.0(108) play store.

Research direction

Reproduce the workflow in Amaze File Manager 3.7.0 (108) on Android 9: encrypt a 2 MB file, upload and download it through Google Drive, then attempt AES decryption with the original password. Compare the downloaded encrypted file and decrypted output with the local originals; done means decryption succeeds and produces the expected non-empty file.
