Hi,

Ingela, I tried your git branch  ssl-asn1-spec-dss-params but unfortunatelly
I still get an exception:

=ERROR REPORT==== 21-Sep-2010::11:57:03 ===

                          [{'OTP-PUB-KEY',
                               check_and_convert_restricted_string,5},

** exception error: no match of right hand side value {error,ecacertfile}


And btw, with the old ssl implementation, using a ssl socket in {active,
once} mode, I receive very often an error like this:

[Thu, 16 Sep 2010 00:10:34 GMT] [error] [<0.604.0>] ** Generic server

                           #Port<0.2288>,nil,open,false,false}


The data, third argument of the tuple, is what is supposed to be. However
the ssl module trows that exception (since it was expecting to receive only
messages like {ssl, Socket, Data}). Is this a known issue?
