Description: A key token is a digital representation of a key that can be used for authentication. These tokens are fundamental in public key infrastructure (PKI), where they enable identity verification and data protection. A key token can be physical, such as a USB device that stores a private key, or digital, like a file containing cryptographic information. Its primary function is to facilitate secure authentication in computer systems, ensuring that only authorized users can access specific resources. Additionally, key tokens may include extra features, such as the ability to digitally sign documents or encrypt information, making them versatile tools in digital security management. The implementation of key tokens is essential in environments where security is critical, as they help prevent unauthorized access and maintain information integrity.
