How to employ OpenSWAN "raw" RSA keys?

[shamrock]

How can I establish an IPSec tunnel between pfSense and an OpenSWAN gateway that requires the use of a "raw" RSA key in RFC 2537 format?

I cannot presently find a way to enter such a "raw" RSA key into pfSense provided to me by the other side, nor can I find a way to generate such a "raw" RSA key in pfSense. I do see the options to use an X.509 certificate or PSK, but such a "raw" RSA key is neither of those two.

I am using a recent build of pfSense 2.0.

Thanks in advance,

I don't think that our IPsec daemon supports keys like that. OpenSWAN does work with PSK mode, however.
