Functions

func ExtractHostname

func ExtractHostname(x509Cert x509.Certificate) string

ExtractHostname returns the hostname from the SAN URIs field of the given certificate: https://golang.org/pkg/crypto/x509/#Certificate.URIs. If the certificate does not have the hostname in the SAN URIs field, an empty string is returned.

func ExtractInstanceId

func ExtractInstanceId(x509Cert x509.Certificate) (string, error)

func ExtractServicePrincipal

func ExtractServicePrincipal(x509Cert x509.Certificate) (string, error)

ExtractServicePrincipal returns the Athenz Service principal for the given certificate which could be either a service certificate or a role certificate. If the certificate does not have the Athenz expected name format the method will an appropriate error.

func ExtractSignerInfo

func ExtractSignerInfo(privateKeyPEM []byte) (crypto.Signer, x509.SignatureAlgorithm, error)

ExtractSignerInfo extract crypto.Signer and x509.SignatureAlgorithm from the given private key (ECDSA or RSA).

func FetchIdToken

func FetchIdToken(ztsURL, svcKeyFile, svcCertFile, svcCACertFile, clientId, scope, nonce, state, keyType string, fullArn *bool, proxy bool, expireTime *int32, roleInAudClaim *bool) (string, error)

func FetchIdTokenExpiryTime

func FetchIdTokenExpiryTime(idToken string) (*time.Time, error)

func GenerateAccessTokenRequestString

func GenerateAccessTokenRequestString(domain, service, roles, authzDetails, proxyPrincipalSpiffeUris, proxyForPrincipal string, expiryTime int) string

GenerateAccessTokenRequestString generates and urlencodes an access token string.

func GetK8SClientAuthCredential

func GetK8SClientAuthCredential(idToken string) (string, error)

func LoadPublicKey

func LoadPublicKey(publicKeyPEM []byte) (interface{}, error)

LoadPublicKey returns public key object for the given PEM data

func LoadX509Certificate

func LoadX509Certificate(certFile string) (*x509.Certificate, error)

LoadX509Certificate reads and parses the x509.Certificate from the specified file.

func ParseAthenzRoleName

func ParseAthenzRoleName(roleName string) (string, string, error)

func ParseGCPResourceName

func ParseGCPResourceName(resource, objectType string) (string, string, error)

func ParsePrincipal

func ParsePrincipal(principal string) (string, string, error)

func ZmsClient

func ZmsClient(zmsURL, keyFile, certFile, caCertFile string, proxy bool) (*zms.ZMSClient, error)

ZmsClient creates and returns a ZMS client instance.

func ZtsClient

func ZtsClient(ztsURL, keyFile, certFile, caCertFile string, proxy bool) (*zts.ZTSClient, error)

ZtsClient creates and returns a ZTS client instance.
