Overview

Package certutil contains helper functions that are mostly used with the PKI backend but can be generally useful. Functionality includes helpers for converting a certificate/private key bundle between DER and PEM, printing certificate serial numbers, and more.

Functionality specific to the PKI backend includes some types // and helper methods to make requesting certificates from the // backend easy.

Functions

func ComparePublicKeys added in v0.4.0

func GetOctalFormatted 

func GetOctalFormatted(buf []byte, sep string) string

func (*CertBundle) ToParsedCertBundle 

func (c *CertBundle) ToParsedCertBundle() (*ParsedCertBundle, error)

ToParsedCertBundle converts a string-based certificate bundle to a byte-based raw certificate bundle

type InternalError 

type InternalError struct {
	Err string
}

InternalError represents an error generated internally, presumably not due to invalid user input

func (InternalError) Error 

func (e InternalError) Error() string

type IssueData 

type IssueData struct {
	TTL        string `json:"ttl" structs:"ttl" mapstructure:"ttl"`

	IPSANs     string `json:"ip_sans" structs:"ip_sans" mapstructure:"ip_sans"`
	CSR        string `json:"csr" structs:"csr" mapstructure:"csr"`
}

IssueData is a structure that is suitable for marshaling into a request; either via JSON, or into a map[string]interface{} via the structs package

type ParsedCSRBundle added in v0.4.0 

type ParsedCSRBundle struct {
	PrivateKeyType  PrivateKeyType
	PrivateKeyBytes []byte
	PrivateKey      crypto.Signer
	CSRBytes        []byte
	CSR             *x509.CertificateRequest
}

ParsedCSRBundle contains a key type, a DER-encoded private key, and a DER-encoded certificate request

func (*ParsedCSRBundle) SetParsedPrivateKey added in v0.4.0 

func (p *ParsedCSRBundle) SetParsedPrivateKey(privateKey crypto.Signer, privateKeyType PrivateKeyType, privateKeyBytes []byte)

SetParsedPrivateKey sets the private key parameters on the bundle

func ParsePKIJSON 

func ParsePKIJSON(input []byte) (*ParsedCertBundle, error)

ParsePKIJSON takes a JSON-encoded string and returns a ParsedCertBundle.

This can be either the output of an issue call from the PKI backend or just its data member; or, JSON not coming from the PKI backend.

func ParsePKIMap 

func ParsePKIMap(data map[string]interface{}) (*ParsedCertBundle, error)

ParsePKIMap takes a map (for instance, the Secret.Data returned from the PKI backend) and returns a ParsedCertBundle.

func (*ParsedCertBundle) GetTLSConfig 

func (p *ParsedCertBundle) GetTLSConfig(usage TLSUsage) (*tls.Config, error)

GetTLSConfig returns a TLS config generally suitable for client authentiation. The returned TLS config can be modified slightly to be made suitable for a server requiring client authentication; specifically, you should set the value of ClientAuth in the returned config to match your needs.

func (*ParsedCertBundle) SetParsedPrivateKey added in v0.4.0 

func (p *ParsedCertBundle) SetParsedPrivateKey(privateKey crypto.Signer, privateKeyType PrivateKeyType, privateKeyBytes []byte)

SetParsedPrivateKey sets the private key parameters on the bundle

func (p *ParsedCertBundle) ToCertBundle() (*CertBundle, error)

ToCertBundle converts a byte-based raw DER certificate bundle to a PEM-based string certificate bundle

type ParsedPrivateKeyContainer added in v0.4.0 

type ParsedPrivateKeyContainer interface {
	SetParsedPrivateKey(crypto.Signer, PrivateKeyType, []byte)
}

ParsedPrivateKeyContainer allows common key setting for certs and CSRs

type PrivateKeyType added in v0.4.0 

type PrivateKeyType string

PrivateKeyType holds a string representation of the type of private key (ec or rsa) referenced in CertBundle and ParsedCertBundle. This uses colloquial names rather than official names, to eliminate confusion 

const (
	UnknownPrivateKey PrivateKeyType = ""
	RSAPrivateKey     PrivateKeyType = "rsa"
	ECPrivateKey      PrivateKeyType = "ec"
)

Well-known PrivateKeyTypes

type Secret 

type Secret struct {
	Data map[string]interface{} `json:"data"`
}

Secret is used to attempt to unmarshal a Vault secret JSON response, as a convenience

type TLSUsage 

type TLSUsage int

TLSUsage controls whether the intended usage of a *tls.Config returned from ParsedCertBundle.GetTLSConfig is for server use, client use, or both, which affects which values are set 

const (
	TLSUnknown TLSUsage = 0
	TLSServer  TLSUsage = 1 << iota
	TLSClient
)

Well-known TLSUsage types

type UserError 

type UserError struct {
	Err string
