Hi, I am running openssh7.3p1 on an embedded Linux system and discovered this problem. If I run: ssh-keygen -t rsa1 -f testfile it appears to generate the key and I get the output: Generating public/private rsa1 key pair. Enter passphrase (empty for no passphrase): Enter same passphrase again: Saving key "testfile" failed: unknown or unsupported key type Should this option be returning with a deprecated key type message ? I can't find a bug already reported about this and I have downloaded openssh 7.4p1 and the problem exists on that too. I have checked the archives at http://marc.info/ and there didn't appear to be anything there. Apologies if this has apready been discussed as I am not on the mailing list. Thanks in advance for any pointers Kelly -- Kelly Dunlop kdunlop@xxxxxxxxxx Guralp Systems Limited http://www.guralp.com _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
