You can generate your own license using the following instructions.

A license is in JWT format, which has three parts: header, payload, and signature. They are joined by .. Header and payload are base64 encoded (base64 without =) JSON objects, and all signature verifications are bypassed, so you can write whatever you like in the signature part. There isn't anything for you to customize in the header. So you can just copy the header from the pre-generated license, or use the following one.

• Support ServerLicense
• Generic hooks (name independent hooking)
  • It seems that JetBrains doesn't change their obfuscated names
  • So, at least for now, generic hooks aren't necessary.
