Verification Policies

For verification of verifiable credentials, the SSIKit provides several predefined, static verification policies. Additionally, it provides a way to create custom policies dynamically, using a policy execution engine, such as Open Policy Agent.
To list the available verification policies and their descriptions, run:
ssikit vc policies list
The output will show the available policies, where static, predefined policies are indicated by the leading -, whereas dynamically created policies are indicated by *:
