Hi
I have found that in R11B-4 ssh has a dependency on asn1, but asn1 is not
included in the ssh.app file.

Hi,

Some aspects of the application concept are a bit fuzzy, and this is
one of them. The 'applications' field in the .app file is used to
specify which applications should be started before this application is.

asn1, however, is a library application in the sense that it has no
supervision tree and thus does not need to be started before it can
be used. What ssh needs is the code for asn1 being available, not that
it is started, but there is (currently) no way of expressing that in
the .app file.

Regards,
Gunilla, Erlang/OTP team

The documentation is a bit unclear, both "Design Principles" and
app(4) says about the 'applications' field that it is all applications that
shall be started, but then they add the comment that
"...all applications have dependencies to at least kernel and stdlib."
Which can give the impression that You actually have to include the
library applications as well.

Unfortunately ssh converts any errors from 'DSS':decode/2 to {error, bad_format}

The "guilty" party is ssh_file:decode_private_key_v2(Private, "ssh-dss")
