[Verse 1] In the world of software supply chains today Trust is fragile, threats are here to stay A package downloads, but how do we know If it's authentic or a malicious show Digital signatures are our first defense Cryptographic proof that makes perfect sense Hash the artifact, sign it with your key Now integrity's guaranteed to be [Chorus] Sign, verify, authenticate Hash plus signature seals our fate Private key to sign the code Public key unlocks the load Certificate chains build the trust Verification is a must Sign, verify, authenticate Keep our software supply chain safe [Verse 2] Alice wants to publish her library code She generates a hash, starts down the road Takes her private key, creates signature Now Bob can verify, be completely sure He downloads the package and the signature too Uses Alice's public key to verify what's true If the hash matches what the signature shows Then Bob knows exactly where this package goes [Chorus] Sign, verify, authenticate Hash plus signature seals our fate Private key to sign the code Public key unlocks the load Certificate chains build the trust Verification is a must Sign, verify, authenticate Keep our software supply chain safe [Bridge] Certificate authorities stand as the root Issuing certificates, building trust routes Key rotation keeps the secrets fresh Revocation lists clean up the mesh From code signing certs to package repos Every artifact's journey someone knows SLSA provenance tells the full story End-to-end security in all its glory [Verse 3] In your build pipeline, make signing routine Automated verification keeps dependencies clean Check the signatures before you deploy Don't let bad actors your systems destroy Registry mirrors, proxy caches too All must verify what they're passing through A broken chain link compromises all So verify each step, both large and small [Chorus] Sign, verify, authenticate Hash plus signature seals our fate Private key to sign the code Public key unlocks the load Certificate chains build the trust Verification is a must Sign, verify, authenticate Keep our software supply chain safe [Outro] When geopolitics threaten our code Cryptographic proof lightens the load Sign every artifact, verify each one Supply chain security's never done Trust but verify, that's the way To keep the bad actors at bay
