USign 1.0.0

Verified to be working with:

• 2021.3.23 OSX
• 2022.2.16 Win

Process:

1. Generate keypair and cert with provided openssl.conf. Cert size in DER format must be 1267 bytes
2. Replace cert in Unity.Licensing.EntitlementResolver.dll using HEX editor or patch binary
3. Modify license.xml template to your needs
4. Generate Unity_lic.ulf signed with private key using sign binary
5. ts.go is an implementation of TimeStamp encoder/decoder just in case.

Usage:

• patch /path/to/Unity.Licensing.EntitlementResolver.dll
• sign
• cp Unity_lic.ulf /path/to/license/dir
