Hello, World!a day agohttps://jyn.dev/first-post/The author is launching a new blog using Jekyll.The blog was inspired by a friend's comment about having a blog after discussing GPG keys.The author hopes to write many posts and invites exploration of the source code.
Using PGP Keysa day agohttps://jyn.dev/using-pgp-keys/GPG is a program for encrypting digital files using the PGP standard mandated by IETF.Encryption ensures only authorized people can read data; it is used in HTTPS and dates back to the Roman empire.Cryptography has two main functions: encrypting data to restrict access and signing data to verify integrity.GPG installation varies by OS: Debian/Ubuntu via apt, Windows via GPG4Win, macOS via GPGtools or brew.GPG uses asymmetric encryption, allowing anyone to send secure messages but only the key owner to decrypt them.To use GPG, you need to generate a key pair (private and public) protected by a passphrase, publish your public key, and start signing things.You can sign Git commits, emails (with Thunderbird, Kmail, etc.), or join Keybase for identity verification.Key generation requires random bytes and appears to run twice because it creates both private and public keys.
