// null byte is added back to force the encoded value to be positive. When the
// sign bit is not set, the encoded integer is just left shorter than usual.
// See also: http://code.google.com/p/chromium/issues/detail?id=14877.
//
// Before we were handling this correctly, we would see one of two failures:
// * RSAPrivateKey::CreateFromPrivateKeyInfo would return null because the
//   underlying windows API failed to import the key.
// * The import would succeed, but incorrectly interpret the data. On export,
//   the key would contain different values.
