// Acknowledgment: ReactOS (GPLv2)
|

|
// https://github.com/reactos/reactos
|
||||||
|
|
||||||
|
// Changed from ReactOS: we never swap the subkeys in order to generate a decryption key schedule. Instead, we opt to simply read the subkeys
|
||||||
|
// in reverse order during a decryption operation. This is necessary because XcKeyTable doesn't provide an "operation" argument, that is, it
|
||||||
|
// always generates an encryption key schedule.
|
||||||
|
|
||||||
|
// NOTE: this des implementation doesn't produce exactly the same ciphertext produced by the Xbox. I found that the implementation of Eric Young
|
||||||
|
// used in OpenSSL does instead, but we can't use it since it's under the Apache 2.0 license, which is incompatible with GPLv2. For reference,
|
||||||
|
// the DES-YOUN.zip package at https://www.schneier.com/books/applied_cryptography/source.html contains a previous version of the same code under
|
||||||
|
// the GPLv2 but again it doesn't produce the same ciphertext, and modifying it to make it so would make it identical to the OpenSSL code, which
|
||||||
|
// is probably a violation of the license, so I won't do it. In practice, as long as the code correctly decrypts the ciphertext (which it does),
|
||||||
|
// I don't think that the Xbox games will care if the ciphertext is not exactly the same as on the Xbox and should work fine offline. The only
|
||||||
|
// problem with this is that cxbxr will be unable to communicate with a real Xbox on the network (des is used in console-to-console communications)
|
||||||
|
// because the des key schedule generated on the console will be different and so it will fail to decrypt packets encrypted by cxbxr.
