PGP Module

Overview

The PGP Module provides Flows steps that can be used to encrypt, decrypt sign or verify messages or files through PGP. The module cannot be used to generate PGP public or private keys. These keys will need to be generated outside of Decisions, using other third party systems.

Prerequisites

• Installation of the PGP module.
• General knowledge of PGP
• A generated public and private PGP key,
  • Public Key: locks the message and converts the key into an encrypted file.
  • Private Key: Unlocks the encrypted file key and converts the message back into plain text.

Example PGP Encryption/Decryption

PGP Steps

Clear Sign File

The Clear Sign File step allows users to sign a file using a private key digitally but keeps the file contents in plain text.

Decrypt File

This Decrypt File step takes in the encrypted file output and uses the private key password to unlock the private key. The Decrypt File step then uses the private key to decrypt the encrypted file.

Decrypt String

The Decrypt String step takes in the data from the Encrypted String output and uses the private Key Password to unlock the private key string. After the private key is unlocked, the message is decrypted into a string using plain text.

Encrypt File

The Encrypt File step takes in data contents and encrypts the message.

Encrypt String

The Encrypt String step takes in data and encrypts the data into a string with a public Key String. It allows a user to view the Public Key String in plain text.

Sign and Encrypt File

The Sign and Encrypt File step uses a private key to digitally sign a file and a public key to encrypt it.

Sign File Step

The Sign File step uses a private key to digitally sign a file. This Step outputs a signed text file and then a Decrypt File step is needed to decrypt and read the file.

Verify File

The Verify File step takes in the output data and then uses the public key to verify that the digital signature is authentic.
