I'd like to read the rsa private key parameters from C#. My idea was
that I just read the base64 encoded string from between the "RSA BEGIN-;
END PRIVATE KEY" lines. I have done it so and I have also dumped the
data as hexa. I compared that with the
'openssl rsa -in mykey.key -text' command output and I found some
additional (info marked with unknown tag) data. I need to know what
these unknown fields means, how the length of each field is stored, to
read any private key params back from a PEM file. The following dump is
an 1024 bit not encoded private key file (which is of course not in use,
just a test key):
