Communicating securely with Sam Gleske

Prerequisites

For Linux GPG, is typically pre-installed. For Mac, install GPG Suite.

Importing my GPG key

Before you can securely send me files and messages, you must first import my GPG public key.

curl -L https://raw.githubusercontent.com/sgleske-ias/gpg/master/sam_gleske.asc | gpg --import

Feel free to edit the trust of my key with:

$ gpg --edit-key 'Sam Gleske'
gpg> trust
gpg> save

Send encrypted files to Sam Gleske

The following encrypts a file to file.asc. Share the encrypted file.asc with me.

gpg -ear 'Sam Gleske' file

For larger files, it's better to create a file.gpg with:

gpg -er 'Sam Gleske' file

Securely managing files from servers

This section is more of a personal note for me.

If files need to be downloaded onto my laptop, then I stream tar into GPG to encrypt it.

ssh HOSTNAME 'tar -cz file1 file2' | gpg -er 'Sam Gleske' -o file.tgz.gpg

To upload and extract the contents from local to a remote server the following command can be run.

gpg -d < file.tgz.gpg | ssh HOSTNAME 'tar -xz'
