X.509v3 is a standard for digital certificates, which are used to verify the authenticity of public keys. Each certificate contains a number of fields that provide information about the certificate's subject, issuer, and public key. The basic certificate fields in X.509v3 include the following attributes:
A. Key usage: This field indicates how the public key in the certificate can be used. It can specify that the key can be used for encryption, signature verification, or other purposes.
B. Certificate serial number: This field is a unique identifier for the certificate. It is assigned by the issuing CA and is used to distinguish between different certificates issued by the same CA.
C. Issuer: This field identifies the entity that issued the certificate. It contains the distinguished name of the issuing CA.
D. Subject name: This field identifies the entity to which the certificate belongs. It contains the distinguished name of the certificate subject.
E. Signature algorithm identifier: This field identifies the algorithm used to sign the certificate.
F. CRL distribution points: This field specifies the location of the certificate revocation list (CRL) for the certificate.
G. Subject alternative name: This field provides additional information about the subject of the certificate. It can include information such as an email address or a DNS name.
In summary, the X.509v3 basic certificate fields include key usage, certificate serial number, issuer, subject name, signature algorithm identifier, CRL distribution points, and subject alternative name.
