Invalid OpenSSL traditional private key format IDP3.x

[Cantor, Scott]

I found the error message in the Java library, but it's not particularly
informative other than the obvious.

I assume you know whether the key was encrypted with a password, and I
also don't know if you're doing a proper upgrade or if you ignored our
instructions and tried to do it from scratch and are now trying to copy
back the old keypair. The default from-scratch install does not
configure things to support a password-protected key. A legacy
relying-party file would have the password in it, probably, but that
wouldn't work with a non-upgraded install.

Lot of variables here, none of them provided in the email to the list.
