Encryption / Decryption

Encryption / Decryption is available utilising the DXC Encryption model.

Once below has been setup, the functionality can be used on the following Finance utilities functionality:

• Encrypt option on Electronic reporting export connections to send encrypted GER Vendor EFT files
• Decrypt option on Financial utilities connection to decrypt a bank statement file imported using periodic task Import bank statements via financial utilities connection

Step 1 - Setup Secrets in Key vault parameters

Setup the following as Secrets in Key vault parameters for the encryption/decryption:

• Phassprase - Longer version of a password used to encrypt the sender’s private key using a hash of the passphrase as the secret key
• Private key - Sender’s private key
• Public key - Sender’s public key
• Receiver’s public key - Receiver’s public key (used for decryption)

Files are encrypted and signed with the sender’s private key, receiver’s public key, and the pass phrase.
Files are verified and decrypted with the recipient’s private key, sender’s public key and the pass phrase.

PGP uses a passphrase to encrypt your private key on your machine. Your private key is encrypted on your disk using a hash of your passphrase as the secret key. You use the passphrase to decrypt and use your private key. A passphrase should be hard for you to forget and difficult for others to guess.

Step 2 - Assign Secrets in DXC encryption parameters

Assign above Secrets to the encryption/decryption.
To open the DXC encryption parameters page, go to Organization administration > Setup > DXC encryption > DXC encryption parameters.

Select New and set the fields as described in the following subsection.

Field	Description
Encryption key name	Enter a unique name for the encryption
Passphrase	Select the applicable Secret from Key vault parameters
Private key	Select the applicable Secret from Key vault parameters
Public key	Select the applicable Secret from Key vault parameters
Receiver’s public key	Select the applicable Secret from Key vault parameters

Step 3 - Use Encryption in Finance utilities

Assign to Finance utilites functionality:

• Encrypt option on Electronic reporting export connections to send encrypted GER Vendor EFT files
• Decrypt option on Financial utilities connection to decrypt a bank statement file imported using periodic task Import bank statements via financial utilities connection.

Setup:

Field	Description
Enable file encryption/decryption	Set to Yes
Encryption key name	Select applicable Encryption key name setup in Step 2
