PGP Decryption in MuleSoft

 

Vendor can share their public key either in asc (Text) or gpg (Binary) extension to their clients so that they can do the decryption and send the decrypted data/files to Vendor. Once vendor receive the decrypted message then they can use their Private Key to decrypt the message. Let’s see how PGP decryption works in MuleSoft.

Before that if you want to understand PGP from starting then please go through below tutorials.

PGP Decryption – We need two things to decrypt in MuleSoft

  • Private Key in gpg format
  • Passphrase
  • Fingerprint

For this POC we will use Private Key we created in our earlier Tutorial – Generate Private Public PGP key

Let’s create a project in MuleSoft

 

Add the Crypto connector in Mule Palette – Checkout this tutorial on how to add module in Anypoint studio

Drag and drop PGP decrypt and Logger into the flow

Add Private_4232E6BD7151FF89D9F755807AC70C45987C59AA.gpg – PGP private key in resources

 

Click on PGP decrypt connector and click on add configuration

 

Populate Private keyring with Private key name we place in resources

  • Click Add symbol to add key detail
  • Add Key id, Fingerprint and Passphrase detail

Click Finish

Configuration will be like below

In logger we will capture the decrypted payload

Now run the application and test the endpoint in SOAP UI, will use the encrypted payload we generated in link

We can see the decrypted message in response

PGP MuleSoft application – pgp-sample-service

PGP SOAP UI application – PGP-Sample-soapui-project
