Properties
Inputs
| Property | Description | Data Type |
|---|---|---|
| File | The desired signed file to decrypt. Using an encrypted PGP file will not throw an error but will not decrypt the file. | FileData |
| Private Key | Generated PGP Private Key file | List of Byte |
| Private Key Password | Password for the specified Private Key file | String |
| Public Key | Generated Public Key file | List of Byte |
Outputs
| Property | Description | Data Type |
|---|---|---|
| Output | Outputs the decrypted file | FileData |

Object reference not set to an instance of an object
If the Data field is null or empty, the step will cause an error.
To correct this, ensure that a signed PGP file is uploaded or mapped to the field.
