OpenSSL 1.1.1 is finally released!
Halleluia, TLS v1.3 for the masses :)
Released on 9/11, COINCIDENCE?
Oh boy oh boy. Did you know that password protected SSH keys regularly store the password hash as md5sum? (Except for ED25519 keys). Well, I didn't.
If your private key starts with something like
Proc-Type: 4,ENCRYPTED
DEK-Info: AES-128-CBC,CB973D5520E952B8D5A6B86716C6223F
yeah, that's the kind. You can re-key though by running
ssh-keygen -o -p -f .ssh/my_private_key

#GitPub is a decentralized federation protocol based on the W3C's #ActivityPub, which extends #ActivityStream 2.0. It provides a server to server API for pull request, forking and subscription of repositories provided by #Git web services (services like #GitHub, #GitLab, #Gogs, #Gitea)... No code yet, but I like the idea! 🙂 https://github.com/git-federation/gitpub

Briefe sind viel sicherer und seriöser als Mails, weil...
...niemand die ganze Post für einen ganzen Konzern zu sich nach Hause umleiten könnte, nur mit einem einfachen Nachsendeauftrag, und dann sackweise Schecks und Daten abgreifen könnte.
Oder?
