Verify File

The Verify File step uses the specified public key to determine whether the input file has an authentic digital signature.

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

Buffer cannot be null

If the Data or Sender Public Key fields are null or empty, the step will cause an error.

To correct this, ensure both fields have an appropriate file uploaded or mapped.
