Summary0005023: ssh-keygen with password doesn't allow conversion in puttygen
Description

Running Kali RasberryPi image updated to latest (2018.4). When creating new keys with ssh-keygen -t rsa and supplying any password it no longer allows conversion in puttygen (version .70). Comparing another Kali build the older ssh-keygen (March 2018) seems to work fine but the latest ssh-keygen (August 2018) has changed 'something' but not sure what.

Everything you need to know is in/usr/share/doc/openssh-server/NEWS.Debian.gz.

OpenSSH 7.8 includes a number of changes that may affect existing
configurations:

  • ssh-keygen(1): Write OpenSSH format private keys by default instead of
    using OpenSSL's PEM format. The OpenSSH format, supported in OpenSSH
    releases since 2014 and described in the PROTOCOL.key file in the
    source distribution, offers substantially better protection against
    offline password guessing and supports key comments in private keys.
    If necessary, it is possible to write old PEM-style keys by adding "-m
    PEM" to ssh-keygen's arguments when generating or updating a key.

Looks like that puttygen only supports the PEM-style private keys. In any case, it's not a Kali bug, possibly a puttygen one about lacking support of the OpenSSH key format.
