How to use Ozeki Phone System Encryption tool to encrypt/decrypt your file

This article introduces the Ozeki Phone System Encryption tool, a great and comfortable option to encrypt or decrypt your files with public or private keys of RSA algorithm. With this tool you are able to browse to your files and RSA keys and create new encrypted or decrypted files with the help of these keys. It is useful when you set up the encryption security in Ozeki Phone System for call recordings and you want to decrypt these recordings.

Call history

If you had set up a call recording rule with file encryption, then you had to get the private key of the RSA key pair. You will ned this key to decrypt your recorded call.

Open your Ozeki Phone System with your personal account (username and password), then find the call history menu option to download your former telephone converstations. Select the PBX features tab on the top of the screen, then the Call history menu option.

Choose the decrypt tab, then find your private key to decrypt your call recording file. You can find the private key at the location where you saved it after RSA key pair creation. Then choose the downloaded call recording file with the help of browse button. Finally select (or create) a target file for the decrypted audio file. The progress bar will show you the status of the decryption. When the process has finished, you can open the decrypted file with Open File button.
