Decrypting a File

A private key is required to decrypt a file.  Because the digital certificate does not hold the private key, it must therefore be associate to a key container.  The private key in the key container is then used to decrypt the file.  To decrypt an encrypted file, take the following steps:

1. Select and highlight the certificate that will be used to decrypt.

   

2. Right click, and scroll to Decrypt File on the popup menu.

   

3. The following dialog box is displayed:

   

   Fill in the information for the following entries in the dialog box:

   • Encrypted File.  Enter the full file path of the file to decrypt.  Click (..) to browse for the file.
   • Format.  Enter the encryption format of the encrypted file.  The following options are available:
     • Encrypted Key.  The encrypted file has a format that is created as follows:
       • A session key is generated and then encrypted using the certificate's public key. 
       • The encrypted key is pre-pended to the encrypted file.
     • EnvelopedData.  This format is based on the PKCS#7 EnvelopedData format.
   • Decrypt File.  Enter the full file path of the resulting decrypted file.  Click (..) to browse for the selected path and target file name.

4. Click OK to accept entries and decrypt file.
