A public key certificate contains the user's ID information (such as name and address), the user's public key, and the Certificate Authority's (CA) information. It also includes a digital signature created by the CA to bind this data together.
Conditions: The certificate is issued by a CA.; The certificate is intended to authenticate a public key.
A public key certificate contains the user's ID information (such as name and address), the user's public key, and the Certificate Authority's (CA) information. It also includes a digital signature created by the CA to bind this data together.
Conditions: The certificate is issued by a CA.; The certificate is intended to authenticate a public key.
The Certificate Authority (CA) creates a digital signature by first applying a cryptographic hash function to the unsigned certificate data to generate a fixed-size hash code. Then, the CA encrypts this hash code using its own private key.
Conditions: The CA possesses the user's identity information and public key.; A cryptographic hash function is available.; The CA has access to its own private key.
