Qdecrypt - README


The Qdecrypt scripts (Bash) can be used to decrypt files from a client side encrypted backup of the QNAP Hybrid Backup Sync Software. The script will decrypt only one file and the script will decrypt a whole folder recursively. In the configuration section of the scripts you can specify the used message digest algorithm (md5 or sha256), because depending on the used software version of OpenSSL and the specified default algorithm, this may vary.


  • Upload the two scripts and to your host.
  • Customize the configuration section at the beginning of the files (optional).
  • Run one of the two scripts without parameters to see the usage instructions.
  • Run the scripts with the necessary parameters to decrypt files/folders.


This is a free script and support is not included and guaranteed. Nevertheless I will try to answer all your questions if possible. So write to my email address biegel[at] if you have a question :-)
