Functions

func GenerateCA

func GenerateCA(keySize int) ([]byte, crypto.PrivateKey, error)

GenerateCA generates a CA certificate and returns the cert bytes as well as the private key used to generate the certificate.

func GenerateClientCert

func GenerateClientCert(caCert *x509.Certificate, caKey crypto.PrivateKey, keySize int, name string) (
	[]byte, crypto.PrivateKey, error)

GenerateClientCert generates a client certificate and returns the cert bytes as well as the private key used to generate the certificate. The CA cert and private key should be passed in. 'user' is the unique username stored in the Subject.CommonName field.

func GenerateServerCert

func GenerateServerCert(caCert *x509.Certificate, caKey crypto.PrivateKey, keySize int, hosts []string) (
	[]byte, crypto.PrivateKey, error)

GenerateServerCert generates a server certificate and returns the cert bytes as well as the private key used to generate the certificate. Takes in the CA cert and key, the size of the key to generate, and the list of hosts/ip addresses this certificate applies to.

func GetCertificateUser

func GetCertificateUser(tlsState *tls.ConnectionState) (string, error)

GetCertificateUser extract the username from a client certificate.

func HashPassword

func HashPassword(raw []byte) ([]byte, error)

HashPassword takes a raw password and returns a bcrypt hashed password.

func LoadClientTLSConfig

func LoadClientTLSConfig(sslCA, sslCert, sslCertKey string) (*tls.Config, error)

LoadClientTLSConfig creates a client TLSConfig by loading the CA and client certs. The following paths must be passed: - sslCA: path to the CA certificate - sslCert: path to the client certificate - sslCertKey: path to the client key If the path is prefixed with "embedded=", load the embedded certs.

func LoadInsecureClientTLSConfig

func LoadInsecureClientTLSConfig() *tls.Config

LoadInsecureClientTLSConfig creates a TLSConfig that disables TLS.

func LoadInsecureTLSConfig

func LoadInsecureTLSConfig() *tls.Config

LoadInsecureTLSConfig creates a TLSConfig that disables TLS.

func LoadServerTLSConfig

func LoadServerTLSConfig(sslCA, sslCert, sslCertKey string) (*tls.Config, error)

LoadServerTLSConfig creates a server TLSConfig by loading the CA and server certs. The following paths must be passed: - sslCA: path to the CA certificate - sslCert: path to the server certificate - sslCertKey: path to the server key If the path is prefixed with "embedded=", load the embedded certs.

func LogTLSState

func LogTLSState(method string, tlsState *tls.ConnectionState)

LogTLSState logs information about TLS state in the form: "<method>: peer certs: [<Subject.CommonName>...], chain: [[<CommonName>...][..]]"

func PromptForPasswordAndHash

func PromptForPasswordAndHash() ([]byte, error)

PromptForPasswordAndHash prompts for a password on the stdin twice, and if both match, returns a bcrypt hashed password.

func ProtoAuthHook

func ProtoAuthHook(insecureMode bool, tlsState *tls.ConnectionState) (
	func(proto.Message, bool) error, error)

ProtoAuthHook builds an authentication hook based on the security mode and client certificate. The proto.Message passed to the hook must implement RequestWithUser.

func ResetReadFileFn

func ResetReadFileFn()

ResetReadFileFn is the counterpart to SetReadFileFn, restoring the original behaviour for loading certificate related data from disk.

func RunCreateCACert

func RunCreateCACert(sslCA, sslCAKey string, keySize int) error

RunCreateCACert is the entry-point from the command-line interface to generate CA cert and key. Takes in: - sslCA: path to the CA certificate - sslCAKey: path to the CA key

func RunCreateClientCert

func RunCreateClientCert(sslCA, sslCAKey, sslCert, sslCertKey string, keySize int, username string) error

RunCreateClientCert is the entry-point from the command-line interface to generate a client cert and key. - sslCA: path to the CA certificate - sslCAKey: path to the CA key - sslCert: path to the node certificate - sslCertKey: path to the node key

func RunCreateNodeCert

func RunCreateNodeCert(sslCA, sslCAKey, sslCert, sslCertKey string, keySize int, hosts []string) error

RunCreateNodeCert is the entry-point from the command-line interface to generate node certs and keys: - sslCA: path to the CA certificate - sslCAKey: path to the CA key - sslCert: path to the node certificate - sslCertKey: path to the node key

func SetReadFileFn

func SetReadFileFn(f func(string) ([]byte, error))

SetReadFileFn allows to switch out ioutil.ReadFile by a mock for testing purposes.

func UserAuthHook

func UserAuthHook(insecureMode bool, tlsState *tls.ConnectionState) (
	func(string, bool) error, error)

UserAuthHook builds an authentication hook based on the security mode and client certificate.

Types

type RequestWithUser

type RequestWithUser interface {
	GetUser() string
}

RequestWithUser must be implemented by `roachpb.Request`s which are arguments to methods that are not permitted to skip user checks.
