Decrypt File

The Decrypt File step enables Users to decrypt a PGP-encrypted file.

Prerequisites 

• This step requires the PGP module to be installed before it will be available in the toolbox. 
• Users must download GPG before utilizing this and other PGP steps. 

Considerations

In v9.18, PGP steps were moved to a legacy category, and new steps were added. While the new PGP steps use an updated encryption/decryption approach (based on AEAD/OCB mode), both categories of steps can be utilized as they have the same functionality.

Common Errors

Object reference not set to an instance of an object

If the File input or the Password for the provided Private Key is null or empty, the step will cause an error.

To correct this, ensure that an encrypted PGP file is uploaded or mapped to the File input and that the password entered for the Private Key is correct.

Value cannot be null

If the Private Key is null or empty, the step will cause an error.

To correct this, ensure that the correct Private Key file is uploaded or mapped.
