At verification time, this is matched via principal name against an authorized_keys-like list of allowed signers.

private keys, enabled via "ssh-keygen -m PKCS8" on operations that save private keys to disk. The OpenSSH native key format remains the default, but PKCS8 is a superior format to PEM if interoperability with non-OpenSSH software is required, as it may use a less terrible KDF (IIRC PEM uses a single round of MD5 as a KDF). adapted from patch by Jakub Jelen via bz3013; ok markus OpenBSD-Commit-ID: 027824e3bc0b1c243dc5188504526d73a55accb1

2019-06-21upstream: Add protection for private keys at rest in RAM againstdjm@openbsd.org
speculation and memory sidechannel attacks like Spectre, Meltdown, Rowhammer and Rambleed. This change encrypts private keys when they are not in use with a symmetic key that is derived from a relatively large "prekey" consisting of random data (currently 16KB). Attackers must recover the entire prekey with high accuracy before they can attempt to decrypt the shielded private key, but the current generation of attacks have bit error rates that, when applied cumulatively to the entire prekey, make this unlikely. Implementation-wise, keys are encrypted "shielded" when loaded and then automatically and transparently unshielded when used for signatures or when being saved/serialised. Hopefully we can remove this in a few years time when computer architecture has become less unsafe. been in snaps for a bit already; thanks deraadt@ ok dtucker@ deraadt@ OpenBSD-Commit-ID: 19767213c312e46f94b303a512ef8e9218a39bd4
