Functions ¶
Types ¶
type AuthorityKeyIdentifier ¶
type AuthorityKeyIdentifier struct {
ID []byte `asn1:"optional,tag:0"`
Issuer asn1.RawValue `asn1:"optional,tag:1"`
SerialNumber *big.Int `asn1:"optional,tag:2"`
}
AuthorityKeyIdentifier represents an X509 authority key identifier extension as defined in RFC 5280 section 4.2.1.1.
id-ce-authorityKeyIdentifier OBJECT IDENTIFIER ::= { id-ce 35 }
AuthorityKeyIdentifier ::= SEQUENCE {
keyIdentifier [0] KeyIdentifier OPTIONAL,
authorityCertIssuer [1] GeneralNames OPTIONAL,
authorityCertSerialNumber [2] CertificateSerialNumber OPTIONAL }
KeyIdentifier ::= OCTET STRING
func (AuthorityKeyIdentifier) Marshal ¶
func (e AuthorityKeyIdentifier) Marshal() ([]byte, error)
Marshal returns the ASN.1 DER-encoding of a value.
func (*AuthorityKeyIdentifier) Unmarshal ¶
func (e *AuthorityKeyIdentifier) Unmarshal(b []byte) error
Unmarshal parses an DER-encoded ASN.1 data structure and stores the result in the object.
type BasicConstraints ¶
type BasicConstraints struct {
IsCA bool `asn1:"optional"`
MaxPathLen int `asn1:"optional,default:-1"`
}
BasicConstraints represents an X509 basic constraints extension as defined in RFC 5280 section 4.2.1.9.
id-ce-basicConstraints OBJECT IDENTIFIER ::= { id-ce 19 }
BasicConstraints ::= SEQUENCE {
cA BOOLEAN DEFAULT FALSE,
pathLenConstraint INTEGER (0..MAX) OPTIONAL }
func (BasicConstraints) Marshal ¶
func (e BasicConstraints) Marshal() ([]byte, error)
Marshal returns the ASN.1 DER-encoding of a value.
func (*BasicConstraints) Unmarshal ¶
func (e *BasicConstraints) Unmarshal(b []byte) error
Unmarshal parses an DER-encoded ASN.1 data structure and stores the result in the object.
type GeneralNames ¶
type GeneralNames struct {
DNSNames []string
DirectoryNames []string
EmailAddresses []string
IPAddresses []net.IP
URIs []*url.URL
}
GeneralNames represents a General Names sequence as defined in RFC 5820 section 4.2.1.6.
GeneralNames ::= SEQUENCE SIZE (1..MAX) OF GeneralName
GeneralName ::= CHOICE {
otherName [0] OtherName,
rfc822Name [1] IA5String,
dNSName [2] IA5String,
x400Address [3] ORAddress,
directoryName [4] Name,
ediPartyName [5] EDIPartyName,
uniformResourceIdentifier [6] IA5String,
iPAddress [7] OCTET STRING,
registeredID [8] OBJECT IDENTIFIER }
OtherName ::= SEQUENCE {
type-id OBJECT IDENTIFIER,
value [0] EXPLICIT ANY DEFINED BY type-id }
EDIPartyName ::= SEQUENCE {
nameAssigner [0] DirectoryString OPTIONAL,
partyName [1] DirectoryString }
func (GeneralNames) Marshal ¶
func (e GeneralNames) Marshal() ([]byte, error)
Marshal returns the ASN.1 DER-encoding of a value.
func (*GeneralNames) Unmarshal ¶
func (e *GeneralNames) Unmarshal(b []byte) error
Unmarshal parses an DER-encoded ASN.1 data structure and stores the result in the object.
