The certificate is also a confirmation or validation by the CA that the public key contained in the certificate belongs to the person, organization, server or other entity noted in the certificate. A CA's obligation in such schemes is to verify an applicant's credentials, so that users and relying parties can trust the information in the issued ...
The Enrollment over Secure Transport, or EST is a cryptographic protocol that describes an X.509 certificate management protocol targeting public key infrastructure (PKI) clients that need to acquire client certificates and associated certificate authority (CA) certificates. EST is described in RFC 7030.
A delegated credential is a short-lived key (from a few hours to a few days) that the certificate's owner delegates to the server for use in TLS. It is in fact a signature: the certificate's owner uses the certificate's private key to sign a delegated public key, and an expiration time.
Alice and Bob have public key certificates issued by Carol, the certificate authority (CA). Alice wishes to perform a transaction with Bob and sends him her public key certificate. Bob, concerned that Alice's private key may have been compromised, creates an 'OCSP request' that contains Alice's certificate serial number and sends it to Carol.
A root certificate is the top-most certificate of the tree, the private key which is used to "sign" other certificates. All certificates signed by the root certificate, with the "CA" field set to true, inherit the trustworthiness of the root certificate—a signature by a root certificate is somewhat analogous to "notarizing" identity in the ...
When you initially get your Real ID driver’s license at a local DMV office, by mail or online, “you must also provide proof of your identity” (such as a certified copy of birth certificate ...
In the X.509 system, there are two types of certificates. The first is a CA certificate. The second is an end-entity certificate. A CA certificate can issue other certificates. The top level, self-signed CA certificate is sometimes called the Root CA certificate. Other CA certificates are called intermediate CA or subordinate CA certificates.
The most common reason for revocation is the user no longer being in sole possession of the private key (e.g., the token containing the private key has been lost or stolen). Hold This reversible status can be used to note the temporary invalidity of the certificate (e.g., if the user is unsure if the private key has been lost).
