[erlang-bugs] SSH problem in R14B

Hi!

It seems like that the (deprecated) function public_key:pem_to_der/1 
doesn't return the same thing as in R14A. As a temporary fix, you can 
change that function from:

pem_to_der(CertSource) ->
     {ok, Bin} = file:read_file(CertSource),
     pubkey_pem:decode(Bin).

to:

pem_to_der(CertSource) ->
     {ok, Bin} = file:read_file(CertSource),
     {ok, pubkey_pem:decode(Bin)}.

Then it should work. Or you can wait until a fix has been pushed.

Best regards,

Niclas @ Erlang/OTP
