Say I have the following private key:

Whenever I try to open it with puttygen.exe, I get a "Couldn't load
private key (unable to create key data structure)" error.

OpenSSL, however, seems to think it's perfectly valid:

openssl rsa -in privatekey.txt -noout -text
openssl asn1parse -inform PEM -in privatekey.txt -i

Which version? 0.60, or the current development code?

After borrowing a friends computer to compile PuTTY (I recently
reformatted mine and haven't reinstalled Visual Studio, yet)... it
works. Thanks!
