Hi,
With latest snapshot on amd64
OpenBSD 6.0-beta (GENERIC.MP) #2197: Sat Jun 18 11:36:59 MDT 2016
I am unable to use the ssh client with public key authentication:
$ ssh bert
Load key "/home/semarie/.ssh/id_bert": invalid format
semarie@bert's password: ^C
$
The ssh server is an openbsd i386 (build from source)
OpenBSD 6.0-beta (GENERIC.MP) #384: Sat Jun 18 06:52:12 CEST 2016
If I revert usr.bin/ssh/sshkey.c to 1.33 (on the client) I am able to
connect with pubkey again.
http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/sshkey.c?rev=1.34&content-type=text/x-cvsweb-markup
translate OpenSSL error codes to something more meaninful;
bz#2522 reported by Jakub Jelen, ok dtucker@
Below is a ssh connection with debug3.
Thanks.
