You can generate a PGP key pair using GPG on your local machine. If you're on a Linux system, GPG is often available by default. On Windows or macOS, you can download and install GPG from the official GnuPG website.
The key generation process will prompt you for various details, such as your name, email address, and a passphrase. Follow the prompts and provide accurate information.
After generating your key pair, ensure you create a secure backup of your private key. Losing your private key means losing access to encrypted messages.
You can upload your public key to PGP key servers. This allows others to find and download your public key, enabling them to send you encrypted messages.
gpg --send-keys <your_key_id>
|
When someone sends you an encrypted message, you can use your private key to decrypt it.
gpg -d encrypted_message.gpg
|
When you want to send an encrypted message to someone else, you'll need their public key. Import their key and use it to encrypt your message.
gpg --import <other_person_public_key.asc>
gpg -e -r <other_person_email> your_message.txt
|
Only use reputable sources for PGP key generation. Trustworthy software like GPG is widely vetted and trusted in the security community. Do not use random websites.
