+== Conclusion
+
+This concludes our implementation of a Secure Supply Chain leveraging Red{nbsp}Hat Trusted Artifact Signer (RHTAS) and the Red{nbsp}Hat Trusted Profile Analyzer (RHTPA). We have demonstrated the complete process, which encompasses building an application from source code, generating a container image, cryptographically signing the resulting binaries, and subsequently verifying that these binaries have been signed by an authorized entity. Future work may focus on the automation of this process and its integration into a Continuous Integration/Continuous Delivery (CI/CD) solution.
