* upstream: remove vestigal support for KRL signaturesdjm@openbsd.org2023-07-171-170/+25
| | | | | | | | | | | | | | | | When the KRL format was originally defined, it included support for signing of KRL objects. However, the code to sign KRLs and verify KRL signatues was never completed in OpenSSH. Now, some years later, we have SSHSIG support in ssh-keygen that is more general, well tested and actually works. So this removes the semi-finished KRL signing/verification support from OpenSSH and refactors the remaining code to realise the benefit - primarily, we no longer need to perform multiple parsing passes over KRL objects. ok markus@ OpenBSD-Commit-ID: 517437bab3d8180f695c775410c052340e038804

* upstream: support for user-verified FIDO keysdjm@openbsd.org2020-08-271-3/+4
| | | | | | | | | | | | | | | | | FIDO2 supports a notion of "user verification" where the user is required to demonstrate their identity to the token before particular operations (e.g. signing). Typically this is done by authenticating themselves using a PIN that has been set on the token. This adds support for generating and using user verified keys where the verification happens via PIN (other options might be added in the future, but none are in common use now). Practically, this adds another key generation option "verify-required" that yields a key that requires a PIN before each authentication. feedback markus@ and Pedro Martelletto; ok markus@ OpenBSD-Commit-ID: 57fd461e4366f87c47502c5614ec08573e6d6a15

* upstream: Refactor signing - use sshkey_sign for everything,djm@openbsd.org2019-10-311-2/+2
| | | | | | | | | | | | | including the new U2F signatures. Don't use sshsk_ecdsa_sign() directly, instead make it reachable via sshkey_sign() like all other signature operations. This means that we need to add a provider argument to sshkey_sign(), so most of this change is mechanically adding that.

* upstream: Add protection for private keys at rest in RAM againstdjm@openbsd.org2019-06-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | 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
