 236 // These two test keys each contain an integer that has 0x00 for its most
 237 // significant byte. When encoded as ASN.1, this byte is dropped and there are
 238 // two interesting sub-cases. When the sign bit of the integer is set, an extra
 239 // null byte is added back to force the encoded value to be positive. When the
 240 // sign bit is not set, the encoded integer is just left shorter than usual.
 241 // See also: http://code.google.com/p/chromium/issues/detail?id=14877.
 242 //
 243 // Before we were handling this correctly, we would see one of two failures:
 244 // * RSAPrivateKey::CreateFromPrivateKeyInfo would return null because the
 245 //   underlying windows API failed to import the key.
 246 // * The import would succeed, but incorrectly interpret the data. On export,
 247 //   the key would contain different values.
 248 //
 249 // This test case verifies these two failures modes don't occur.
