If the certificate-check ocsp none command is configured for a certificate, the OCSP mode is used first. If the OCSP mode is unavailable, the certificate is regarded as valid. If the certificate-check crl ocsp command is configured for a certificate, the CRL mode is used first. If the OCSP mode is unavailable, the certificate is regarded as invalid. If the certificate-check ocsp crl command is configured for a certificate, the OCSP mode is used first.
If the CRL mode is unavailable, the certificate is regarded as invalid. If the certificate-check crl ocsp none command is configured for a certificate, the CRL mode is used first. If the certificate-check ocsp crl none command is configured for a certificate, the OCSP mode is used first.
If the certificate-check none command is configured for a certificate, the certificate is regarded as valid. Certification authority CA : Issues certificates to users, computers, and services and manages certificates. A certification authority signs each certificate it issues with its own digital certificate. Registration authority RA : The interface between the user and the certification authority.
It is responsible for identifying applicants or certificate holders and ensuring that the certificate usage constraints are met. Central Directory CD : Responsible for storing digital certificates. It centralizes and organizes the archiving of certificates. It also manages the list of expired or revoked certificates CRL and makes public-key certificates issued by the certification authority available to all users.
Cryptography Cryptography provides a way to protect data by converting it into an unreadable format for transmission or storage purposes. Cryptography is an important technology for electronic commerce, intranets, extranets, and many other web applications.
There are two types of cryptography techniques: symmetric and asymmetric. Symmetric and asymmetric keys are used to provide a variety of security functions. Symmetric cryptography Symmetric encryption uses the same key for encryption and decryption. When encrypting data, the sender uses the symmetric key to ensure that an unauthorized person or process cannot access the original data.
The recipient uses the same symmetric key to decrypt the data once they receive it. Asymmetric cryptography Asymmetric encryption uses a pair of keys to encrypt and decrypt data. The public key encrypts the data, and the associated private key decrypts data.
The private key is intended to never be exposed to network users. It is stored in a physical device, such as a smart card or a computer. The public key, which is an attribute of the certificate, is widely distributed in the network to allow users to perform encryption operations and digitally sign data. Digital signature The digital signature process ensures the authenticity of the sender authentication function and verifies the integrity of the received message.
The digital signature also provides a non-repudiation function: it prevents the sender from denying having sent the message. It contains the algorithm identifier hash function used by the certification authority to sign the certificate and the value of the digital signature. The function always returns the same hash value if the message is not changed.
