NAME

SBOM::CycloneDX::CryptoProperties::CertificateExtension - Certificate Extensions

SYNOPSIS

SBOM::CycloneDX::CryptoProperties::CertificateExtension->new();

DESCRIPTION

SBOM::CycloneDX::CryptoProperties::CertificateExtension A certificate extension is a field that provides additional information about the certificate or its use. Extensions are used to convey additional information beyond the standard fields.

METHODS

SBOM::CycloneDX::CryptoProperties::CertificateExtension->new( %PARAMS )

Properties:

common_extension_name, The name of the extension.

  • basicConstraints, Specifies whether a certificate can be used as a CA certificate or not.

  • keyUsage, Specifies the allowed uses of the public key in the certificate.

  • extendedKeyUsage, Specifies additional purposes for which the public key can be used.

  • subjectAlternativeName, Allows inclusion of additional names to identify the entity associated with the certificate.

  • authorityKeyIdentifier, Identifies the public key of the CA that issued the certificate.

  • subjectKeyIdentifier, Identifies the public key associated with the entity the certificate was issued to.

  • authorityInformationAccess, Contains CA issuers and OCSP information.

  • certificatePolicies, Defines the policies under which the certificate was issued and can be used.

  • crlDistributionPoints, Contains one or more URLs where a Certificate Revocation List (CRL) can be obtained.

  • signedCertificateTimestamp, Shows that the certificate has been publicly logged, which helps prevent the issuance of rogue certificates by a CA. Log ID, timestamp and signature as proof

common_extension_value, The value of the certificate extension.

Custom extensions may convey application-specific or vendor-specific data not covered by standard extensions. The structure and semantics of custom extensions are typically defined outside of public standards. CycloneDX leverages properties to support this capability.

custom_extension_name, The name for the custom certificate extension.
custom_extension_value, The description of the custom certificate extension.
