This ensures that only the intended person can decrypt it with their own private key.

Now, let me explain how this works in more detail. First, you need to generate your keys by running `gpg –full-generate-key` command in your terminal window. You will be prompted for a passphrase which is like a secret code that only you know. This ensures that no one else can access your private key and decrypt the files.

Next, when you want to send an encrypted file to someone, you need their public key. If they have uploaded it to a public key server (like MIT), you can search for it using `gpg –keyserver pgp.mit.edu –search-keys [email protected]` command in your terminal window. This will list all the matches and you can choose which one belongs to Mary Geek by typing its number and pressing Enter.

Once you have their public key, you can encrypt a file using `gpg -c filename` command in your terminal window. This will create an encrypted version of the file with a .gpg extension. The recipient can then decrypt it using their private key by running `gpg –decrypt filename.gpg` command in their own terminal window.

Now, let’s say you want to verify someone’s public key before trusting them. You can do this by running `gpg –fingerprint` command and comparing the fingerprint with what they have provided you. If it matches, then you know that the key belongs to them and is safe to use.

Overall, GPG provides a secure way of sharing files without worrying about anyone else accessing them. It’s like having your own secret code that only you and the intended recipient can understand!

In terms of privacy concerns in Linux, sometimes the packaging system may become broken, which can lead to issues with rebooting or troubleshooting. To avoid this, executing a few simple commands using dpkg can help fix any potential problems. This is especially useful for developers who need to monitor logs and clean out filesystems when applications go down and customers are being affected. By having basic knowledge of your entire environment (including business aspects), you become more valuable to your manager and can avoid being labeled as clueless.
