A key escrow system is not primarily used for issuing certificates, managing CRLs, or verifying digital signatures. Its main purpose is to securely store copies of encryption keys.
A key escrow system in PKI is designed to securely store copies of encryption keys. The primary purpose is to ensure that encrypted data can be recovered if the original keys are lost or unavailable. This is particularly important in corporate or government settings where data loss could have serious consequences. Key escrow systems allow authorized parties, such as law enforcement agencies or corporate administrators, to access encrypted data under specific, predefined circumstances, while maintaining the confidentiality and security of the keys under normal conditions.
