Go PGP Utility

This project provides a set of Go utilities for performing PGP encryption and decryption, as well as some file manipulation tasks like writing to TXT, CSV, and creating ZIP archives.

Features

• PGP Encryption: Encrypt files using a public PGP key.
• PGP Decryption:
  • Decrypt files using a private PGP key and a passphrase.
  • Decrypt files using a private PGP key from a keyring (without a passphrase if the key is not encrypted).
• File Utilities:
  • Write content to text files.
  • Write data to CSV files.
  • Create ZIP archives from a list of files.

Prerequisites

• Go (version 1.18 or later recommended)
• PGP keys (public and private) for testing encryption and decryption.

Dependencies

• github.com/ProtonMail/gopenpgp/v3

go mod tidy
# or
go get github.com/ProtonMail/gopenpgp/v3/crypto

Setup

1. Clone the repository (if applicable) or ensure you have the project files.

2. Place your PGP keys:

   • For encryption: public.pgp (or update the path in main.go)
   • For decryption with passphrase: private.pgp (or update the path in main.go)
   • For decryption with keyring: secret.asc (or update the path in main.go)

3. Prepare input files:

   • Create a file decrypted/test.txt with content to be encrypted.
   • Place an encrypted file at encrypted/test.txt.zip.pgp for decryption with passphrase.
   • Place an encrypted file at encrypted/test.csv.gpg for decryption with keyring.
   • Ensure the output directories (e.g., decrypted/, encrypted/) exist or create them.
