Many signing tools today assume that the signing key resides on the local computer the tool is being executed on. Similarly, hardware security module (HSM) APIs default to assuming the data that needs to be signed resides on the machine that is directly connected to the HSM. Of course, the former scenario presents major security risks, while the latter is not the case with hash signing.
Deploying a client-side hash signing architecture with existing tools, all while keeping the signing keys securely locked away in an enterprise HSM or key manager, is an extremely complex task. It requires a lot of low-level development work from cryptography experts that transparently do all the heavy lifting for you.
Fortunately, that is exactly what the team at Garantir loves to do. We designed our flagship product, GaraSign, to come with these cryptographic providers ready to use out of the box on all major platforms including Apple, Microsoft, Java, Android, GPG, RPM, Linux, OpenSSL, and more. Whether you are signing code, documents, challenge-response handshakes, or any other type of data, GaraSign’s client integrations make this a seamless experience for your end users.
