      public AgentCardSignature.Builder signature(String signature)
      Sets the Base64URL-encoded signature value.
      Parameters:
      signature - the Base64URL-encoded signature (required)
      Returns:
      this builder for method chaining

    • build

      public AgentCardSignature build()
      Builds a new immutable AgentCardSignature from the current builder state.
      Returns:
      a new AgentCardSignature instance
      Throws:
      IllegalArgumentException - if protectedHeader or signature is null
