2018-10-11supply callback to PEM_read_bio_PrivateKeyDamien Miller
OpenSSL 1.1.0i has changed the behaviour of their PEM APIs, so that empty passphrases are interpreted differently. This probabalistically breaks loading some keys, because the PEM format is terrible and doesn't include a proper MAC. Avoid this by providing a basic callback to avoid passing empty passphrases to OpenSSL in cases where one is required. Based on patch from Jakub Jelen in bz#2913; ok dtucker@
2018-10-09upstream: Treat all PEM_read_bio_PrivateKey() errors when a passphrasedjm@openbsd.org
is specified as "incorrect passphrase" instead of trying to choose between that and "invalid format". libcrypto can return ASN1 parsing errors rather than the expected decrypt error in certain infrequent cases when trying to decrypt/parse PEM private keys when supplied with an invalid passphrase.

2018-07-03upstream: Improve strictness and control over RSA-SHA2 signaturedjm@openbsd.org
In ssh, when an agent fails to return a RSA-SHA2 signature when requested and falls back to RSA-SHA1 instead, retry the signature to ensure that the public key algorithm sent in the SSH_MSG_USERAUTH matches the one in the signature itself. In sshd, strictly enforce that the public key algorithm sent in the SSH_MSG_USERAUTH message matches what appears in the signature. Make the sshd_config PubkeyAcceptedKeyTypes and HostbasedAcceptedKeyTypes options control accepted signature algorithms (previously they selected supported key types). This allows these options to ban RSA-SHA1 in favour of RSA-SHA2. Add new signature algorithms "rsa-sha2-256-cert-v01@openssh.com" and "rsa-sha2-512-cert-v01@openssh.com" to force use of RSA-SHA2 signatures with certificate keys. feedback and ok markus@ OpenBSD-Commit-ID: c6e9f6d45eed8962ad502d315d7eaef32c419dde
