--- Comment #5 from Juan Lang juan.lang@gmail.com 2011-10-26 18:01:39 CDT --- I ran it with a debug patch (which I'll attach in a sec), and it appears that rsaenh is expecting the input buffer to be one byte longer than it is:
err:crypt:import_private_key blob too short for pub key: expect 596, got 595
I don't know what the reason for the error is, whether it's an application bug that Microsoft expects, or whether it's a logic bug in rsaenh.
