Updating expired GPG keys and their backup 🔑🔐💻

I use a GPG key to sign my git commits.

An error like this one might be a sign of an expired GPG key.

Allgemeines

Anrede: Wenig förmlich:

• "Du"-Form
• Keine gruseligen "Amtsdeusch"-Umschreibungen, einfach so als ob man den Nutzer direkt persönlich ansprechen würde

Genauer definiert:

• "falsch" anstatt "nicht korrekt/inkorrekt"
• Benutzerkonto oder Konto? Oder Account?
• "Wende dich an ..." anstatt "kontaktiere ..."

Migrate GPG Keys from One Workstation to Another

Replace [your key] with your key ID

To obtain your key ID

gpg --list-secret-keys --keyid-format LONG

Which returns something like

sgdan

import java.io.ByteArrayOutputStream
import java.io.File
import java.nio.charset.StandardCharsets.UTF_8
import java.util.zip.GZIPInputStream
import java.util.zip.GZIPOutputStream

fun gzip(content: String): ByteArray {
    val bos = ByteArrayOutputStream()
    GZIPOutputStream(bos).bufferedWriter(UTF_8).use { it.write(content) }
    return bos.toByteArray()
