    The core technology of cloud signing service is HASH Signing

    ZoTrus code signing cloud service adopts the "client-to-cloud separation and collaboration" architecture. Its core technology is "HASH Signing". It does not upload code to the cloud, but only submits the HASH value to complete the cloud signing. It builds the highest level of data security firewall for users. This is a cloud signing service that can be trusted.

    Code signing Cloud service will become the first choice for signing code.

    Code signing Cloud service will become the first choice for signing code.

    Code signing cloud service not only solves the problem of users having to wait for UKey certificates delivered from the US, but also solves the problem of the ever-shortening validity period of code signing certificates. And it will solve the problem of post-quantum cryptography signature migration free of charge. Users can enjoy the convenient cloud services to sign software code on demand.

    Why must code signing have timestamps?

    Why must code signing have timestamps?

    ZoTrus Code Signing Cloud Service automatically adds a globally trusted timestamp signature to each signing, ensuring that the digital signature of the code remains valid even after the code signing certificate expires, thus guaranteeing the security and trustworthiness of the software throughout its entire lifecycle.
