Code signing is the process of applying a digital signature to software and mobile apps. This is essential for building trust in DevOps at scale. Rising software supply chain attacks make this protection urgent. And businesses can’t afford to ignore data security in 2025. Especially when code signing certificates are also facing issues due to attacks on security key management and storage. Another challenge is the new 460-day validity mandate by the CA/B Forum. This means frequent code signing certifications, which were previously valid for up to 39 months. So enterprises looking to secure access to certificates and security keys across development and production teams need to have a strategic approach. Two hardware-backed approaches are frequently used to safeguard private signing keys. One is YubiKey, and the other is Cloud HSM. Each enables strong, non-exportable key protection for signing workflows. This article compares YubiKey and Cloud HSM for DevOps code signing, focusing on automation in CI/CD, scalability, collaboration, compliance, and operational overhead to help teams pick the right fit for their pipelines. What Is Code Signing? Code signing utilizes public key cryptography to bind a publisher’s identity to a software or app. Certificate Authority (CA) then checks the signature against […]
