+## Task 1
+### Commit Signing Benefits:
+
+Commit signing helps to verify identity of developer who made the commit and ensures that code was not modified by unauthorized users. It increases trust in codebase and improves security.
+
+### Evidence of SSH Key Setup and Signed Commit
+
+- SSH key was successfully generated and added to GitHub
+- Git was configured to use SSH for commit signing
+- A signed commit was created using the -S flag
+- The commit shows a "Verified" badge on GitHub
+
+### Why is commit signing important in DevOps workflows?
+
+Commit signing guarantees authenticity and integrity of code changes. It prevents malicious contributions, ensures accountability, and helps teams to trust source of every commit in the repository.
