The results of a little spike into how to create RSA keys in .NET.
Usage: KeyCreator [options]
Options: --help Display help. -f --filename Specify output filename. Defaults to 'rsa_key'. -s --size Specify key size in bits. Defaults to '2048'.
NIST guidelines recommend that keys should be at least 2048 bits. Fun fact, .NET won't let you use a key smaller than 2048 bits for signing. Figuring that out is an hour of my life I won't get back.
