Member Enumeration Documentation

◆ Value

enum pcpp::X509ExtensionType::Value : uint8_t

Enumeration of supported X.509 extension types

Enumerator
BasicConstraints	Basic Constraints - Indicates if the subject is a CA and the maximum path length.
KeyUsage	Key Usage - Defines the purpose of the key contained in the certificate.
ExtendedKeyUsage	Extended Key Usage - Indicates one or more purposes for which the certified public key may be used.
SubjectKeyIdentifier	Subject Key Identifier - Provides a means of identifying certificates that contain a particular public key
AuthorityKeyIdentifier	Authority Key Identifier - Identifies the public key used to verify the signature on this certificate.
SubjectAltName	Subject Alternative Name - Allows identities to be bound to the subject of the certificate.
IssuerAltName	Issuer Alternative Name - Allows additional identities to be associated with the issuer.
CrlDistributionPoints	CRL Distribution Points - Identifies how CRL information is obtained.
AuthorityInfoAccess	Authority Information Access - Describes how to access CA information and services.
CertificatePolicies	Certificate Policies - Contains a sequence of one or more policy terms.
PolicyMappings	Policy Mappings - Used in CA certificates to indicate that one or more policies can be considered equivalent
PolicyConstraints	Policy Constraints - Specifies constraints on path validation.
NameConstraints	Name Constraints - Indicates a name space within which all subject names in subsequent certificates must be located
InhibitAnyPolicy	Inhibit Any Policy - Indicates that the special anyPolicy OID is not considered an explicit match for other certificate policies
CTPrecertificateSCTs	Signed Certificate Timestamp - Contains a list of SCTs from Certificate Transparency logs.
SubjectInfoAccess	Subject Information Access - Describes how to access additional information about the subject.
FreshestCRL	Freshest CRL - Identifies how delta CRL information is obtained.
TLSFeature	TLS Feature - Indicates which TLS features are required for the certificate to be used.
OcspNoCheck	OCSP No Check - Indicates that an OCSP client should trust the certificate for OCSP signing.
SubjectDirectoryAttributes	Subject Directory Attributes - Conveys identification attributes of the subject.
Unknown	Unknown or unsupported extension type.

Parameters

[in] value the extension type enum value

Member Function Documentation

◆ fromOidValue()

static X509ExtensionType pcpp::X509ExtensionType::fromOidValue ( const Asn1ObjectIdentifier & value )

static

Creates an X509ExtensionType from an OID value

Parameters

[in] value The ASN.1 object identifier

Returns: The corresponding X509ExtensionType value, or Unknown if no match is found

◆ getOidValue()

std::string pcpp::X509ExtensionType::getOidValue ( ) const

Returns: The OID value of the extension

◆ toString()

std::string pcpp::X509ExtensionType::toString ( ) const

Returns: A string representation of the extension type
