Signing and Verification
Signing is how you turn "trust me, this artifact is authentic" into "verify it yourself." A cryptographic signature binds an artifact to its producer and proves it hasn't been tampered with since. But traditional signing has a painful key-management problem, and the modern answer — keyless signing with Sigstore — is what finally made artifact signing practical enough to be routine.
