type AlgorithmIdentifier

type AlgorithmIdentifier struct {
	Algorithm  asn1.ObjectIdentifier
	Parameters asn1.RawValue `asn1:"optional"`

AlgorithmIdentifier represents the ASN.1 structure of the same name. See RFC 5280, section

type AttributeTypeAndValue

type AttributeTypeAndValue struct {
	Type  asn1.ObjectIdentifier
	Value interface{}

AttributeTypeAndValue mirrors the ASN.1 structure of the same name in RFC 5280, Section

type AttributeTypeAndValueSET added in go1.3

type AttributeTypeAndValueSET struct {
	Type  asn1.ObjectIdentifier
	Value [][]AttributeTypeAndValue `asn1:"set"`

AttributeTypeAndValueSET represents a set of ASN.1 sequences of AttributeTypeAndValue sequences from RFC 2986 (PKCS #10).

type CertificateList

type CertificateList struct {
	TBSCertList        TBSCertificateList
	SignatureAlgorithm AlgorithmIdentifier
	SignatureValue     asn1.BitString

CertificateList represents the ASN.1 structure of the same name. See RFC 5280, section 5.1. Use Certificate.CheckCRLSignature to verify the signature.

func (*CertificateList) HasExpired

func (certList *CertificateList) HasExpired(now time.Time) bool

HasExpired reports whether certList should have been updated by now.

type Extension

type Extension struct {
	Id       asn1.ObjectIdentifier
	Critical bool `asn1:"optional"`
	Value    []byte

Extension represents the ASN.1 structure of the same name. See RFC 5280, section 4.2.

type Name

type Name struct {
	Country, Organization, OrganizationalUnit []string
	Locality, Province                        []string
	StreetAddress, PostalCode                 []string
	SerialNumber, CommonName                  string

	// Names contains all parsed attributes. When parsing distinguished names,
	// this can be used to extract non-standard attributes that are not parsed
	// by this package. When marshaling to RDNSequences, the Names field is
	// ignored, see ExtraNames.
	Names []AttributeTypeAndValue

	// ExtraNames contains attributes to be copied, raw, into any marshaled
	// distinguished names. Values override any attributes with the same OID.
	// The ExtraNames field is not populated when parsing, see Names.
	ExtraNames []AttributeTypeAndValue

Name represents an X.509 distinguished name. This only includes the common elements of a DN. Note that Name is only an approximation of the X.509 structure. If an accurate representation is needed, asn1.Unmarshal the raw subject or issuer as an RDNSequence.

func (*Name) FillFromRDNSequence

func (n *Name) FillFromRDNSequence(rdns *RDNSequence)

FillFromRDNSequence populates n from the provided RDNSequence. Multi-entry RDNs are flattened, all entries are added to the relevant n fields, and the grouping is not preserved.

func (Name) String added in go1.10

func (n Name) String() string

String returns the string form of n, roughly following the RFC 2253 Distinguished Names syntax.

func (Name) ToRDNSequence

func (n Name) ToRDNSequence() (ret RDNSequence)

ToRDNSequence converts n into a single RDNSequence. The following attributes are encoded as multi-value RDNs:

- Country
- Organization
- OrganizationalUnit
- Locality
- Province
- StreetAddress
- PostalCode

Each ExtraNames entry is encoded as an individual RDN.

type RDNSequence

type RDNSequence []RelativeDistinguishedNameSET

func (RDNSequence) String added in go1.10

func (r RDNSequence) String() string

String returns a string representation of the sequence r, roughly following the RFC 2253 Distinguished Names syntax.

type RelativeDistinguishedNameSET

type RelativeDistinguishedNameSET []AttributeTypeAndValue

type RevokedCertificate

type RevokedCertificate struct {
	SerialNumber   *big.Int
	RevocationTime time.Time
	Extensions     []Extension `asn1:"optional"`

RevokedCertificate represents the ASN.1 structure of the same name. See RFC 5280, section 5.1.

type TBSCertificateList

type TBSCertificateList struct {
	Raw                 asn1.RawContent
	Version             int `asn1:"optional,default:0"`
	Signature           AlgorithmIdentifier
	Issuer              RDNSequence
	ThisUpdate          time.Time
	NextUpdate          time.Time            `asn1:"optional"`
	RevokedCertificates []RevokedCertificate `asn1:"optional"`
	Extensions          []Extension          `asn1:"tag:0,optional,explicit"`

TBSCertificateList represents the ASN.1 structure of the same name. See RFC 5280, section 5.1.
