Decrypt File and Save Decrypted Output to Another File

Make sure pfEncryptor is started and you are on the main form.

See Decryption Definition Form for a description of the various fields on the form.

In the Decrypt portion of the main form:

• Click Decrypt File to identify this as a file decryption.
• Select the type of encryption to use: AES or TDES or DES.
• See Encryption Algorithms for a description of the encryption standards used by this application..
• Specify the Key and IV to use for this decryption.
• If you have a file containing the key and IV combination that was used to encrypt the data::
• Click Load Key/IV From File button.
• Select the folder and file containing the key that was used and press the Open button.
• If you know the key that was used to encrypt the data, you can type the key and IV directly to the Key and IV fields on the Decryption Definition Form.
• If the Key and IV are already displayed on Encryption Definition Form, you can click the Copy Key/IV From Above button to copy the information to the decryption form.
• (Optional) If you want to save a copy of the Key/IV values::
• Click the Save Key/IV To File button.
• Specify the folder and file name using the Save File Dialog that shows.
• Click the Save button.
• Specify the file to be decrypted.
• Click the Source Button to show a File Open Dialog.
• Select Save Decrypted Output to File option button to save output to a file.
• Check the Binary Encryption check box if the data in the input file is in binary format.
• Leave this option unchecked if the encrypted data is in Base64 text format.
• See Choosing Binary or Base64 for Encryption Output for more information on the different encryption formats.
• (Optional) Specify the full path for the output file.
• Use the Output Button to display a File Save Dialog.
• If you do not specify the output file path, the decrypted file will be given a name by the application and will be stored in the same folder as the encrypted file.
• Click the Decrypt Button.
• The Decrypted output has been stored in the file path listed in the Decrypted Output field.
• (Optional) Click the Save button to save the Decryption Definition to a file.
• To use this saved Decryption Definition at some later time, use the Load button to open and load the saved definition to the Decrypt form.
• See Open Saved Decryption Definition for information rerunning a previously defined encryption.
• (Optional) Click the New button to clear the Decryption Definition Form and start a new definition.
