How to decrypt S/MIME files.

 

Answer:

 

Decrypting S/MIME Files

You can decrypt RSA standard PKCS7 S/MIME email items. This includes MBOX, DBX, RFC822, and some PST/EDB archives. You cannot decrypt PGP encrypted emails, Lotus Notes proprietary encryption. and items with S/MIME signatures -- only the S/MIME encryption.

 

The Key files are PFX and PEM The Key files are flagged and kept track of during processing in the same way as EFS and NSF key files. 

 

To decrypt S/MIME

  1. In case, click Tools > Decrypt Files.
  2. In the Decrypt Files dialog, type a password in the Password box.
    2a. Confirm the pass word by typing it again in the Confirm Password box.
  3. Mark Permanently Mask to display the password as asterisks in the Saved Passwords list, hiding the actual password. 
  4. Click Save Password to save the password into the Save Password List.
  5. Mark Attempt Blank Password to decrypt files with no password, or whose password is blank.
    NOTE: S/MIME encrypted files in the case are automatically detected. Decrypt File Types will automatically be marked according to the file types found. Unselect any file types you wish not to decrypt. 
  6. Click Decrypt to begin the decryption process.
    NOTE: The Decrypt button is disabled until at least one password is entered, or until Attempt Blank Password is marked.
  7. When decryption is complete, click OK to return to the case.
