To update the algorithm used to perform encryption in the CE50-10:
1. Hitachi provides the new algorithm as package files (extension .deb) containing OpenSSL binary data that
implements encryption.
2. Start the unit in normal mode.
3. Copy the package files.
Use the following command to create the directory where the package files are to be placed.
$ mkdir /tmp/opessl_update
Copy all the package files from the external media or maintenance PC to the directory you created.
4. Run the following command.
$ sudo apt -y install /tmp/openssl_update/*.deb
This ends the procedure for updating the encryption algorithm.
