PGP Decrypt

Overview

Pretty Good Privacy (PGP) is a decryption program that provides cryptographic privacy and authentication for data communication. PGP is popularly used to digitally sign, encrypt or decrypt email messages or files being transferred over the Internet.

This Snap decrypts PGP-encrypted data provided as an input stream using the private key and passphrase. This Snap should be attached to the input binary data stream to be decrypted in the pipeline.
Warning: The default security in the JRE limits the key length for encryption keys. For stronger encryption keys, you would need to manually install the Java Cryptographic Extension JARs on your JCC nodes.


Limitations and known issues

The Snap might fail while processing very large signed files.

Snap views

View Description Examples of upstream and downstream Snaps
Input Any Snap that produces binary data in the output view such as File Reader or Compress.

Stream of PGP encrypted data.
Output Any Snap that accepts binary data in the input view such as File Writer or Decompress.

Stream of PGP decrypted data.
Error

Error handling is a generic way to handle errors without losing data or failing the Snap execution. You can handle the errors that the Snap might encounter when running the pipeline by choosing one of the following options from the When errors occur list under the Views tab. The available options are:

  • Stop Pipeline Execution Stops the current pipeline execution when an error occurs.
  • Discard Error Data and Continue Ignores the error, discards that record, and continues with the remaining records.
  • Route Error Data to Error View Routes the error data to an error view without stopping the Snap execution.

Snap settings

Legend:
  • Expression icon (): Allows using pipeline parameters to set field values dynamically (if enabled). SnapLogic Expressions are not supported. If disabled, you can provide a static value.
  • SnapGPT (): Generates SnapLogic Expressions based on natural language using SnapGPT. Learn more.
  • Suggestion icon (): Populates a list of values dynamically based on your Snap configuration. You can select only one attribute at a time using the icon. Type into the field if it supports a comma-separated list of values.
  • Upload : Uploads files. Learn more.
Learn more about the icons in the Snap settings dialog.
Field / Field set Type Description
Label String

Required. Specify a unique name for the Snap. Modify this to be more appropriate, especially if more than one of the same Snaps is in the pipeline.

Default value: PGP Decrypt

Example: PGP Decrypt
Signed File Checkbox Specify if the selected file is a signed file.

Default status: Deselected
Skip Verification Checkbox Select this checkbox to skip the verification if there is an issue with the signature in the encrypted file.

Default status: Deselected
Snap execution Dropdown list
Choose one of the three modes in which the Snap executes. Available options are:
  • Validate & Execute: Performs limited execution of the Snap and generates a data preview during pipeline validation. Subsequently, performs full execution of the Snap (unlimited records) during pipeline runtime.
  • Execute only: Performs full execution of the Snap during pipeline execution without generating preview data.
  • Disabled: Disables the Snap and all Snaps that are downstream from it.

Default value: Execute only

Example: Validate & Execute
