# RSAPatch
|
||||
A patch to get into grass cutting for a certain anime game
|
||||
## How to Use?
|
||||
|
||||
- Download dll from release or compile it yourself
|
||||
- Rename it to `version.dll` or `mhypbase.dll` and put it in the same folder as the game
|
||||
- Create a file named `PublicKey.txt` under the same folder as the game and put your public key in there
|
||||
- **[Optional]** If you need to replace the private key, create a file named `PrivateKey.txt` under the same folder and put your private key in there
|
||||
- Finally start the game, if you done it right, there should be a console window popup
|
||||
## Infos
|
||||
- For Grasscutter, only the public key is needed for now.
|
||||
- Tested on 3.1, 3.2, and 3.2.50. It should work for future versions too, unless they have new protections
|
||||
- **DO NOT** create `PrivateKey.txt` if you don't need it
|
||||
- Public key for Grasscutter: `<RSAKeyValue><Modulus>xbbx2m1feHyrQ7jP+8mtDF/pyYLrJWKWAdEv3wZrOtjOZzeLGPzsmkcgncgoRhX4dT+1itSMR9j9m0/OwsH2UoF6U32LxCOQWQD1AMgIZjAkJeJvFTrtn8fMQ1701CkbaLTVIjRMlTw8kNXvNA/A9UatoiDmi4TFG6mrxTKZpIcTInvPEpkK2A7Qsp1E4skFK8jmysy7uRhMaYHtPTsBvxP0zn3lhKB3W+HTqpneewXWHjCDfL7Nbby91jbz5EKPZXWLuhXIvR1Cu4tiruorwXJxmXaP1HQZonytECNU/UOzP6GNLdq0eFDE4b04Wjp396551G99YiFP2nqHVJ5OMQ==</Modulus><Exponent>AQAB</Exponent></RSAKeyValue>`
