Functions

func EncryptBytes

func EncryptBytes(key string, data []byte) ([]byte, error)

EncryptBytes encrypts a row of data using AES-CFB.

func GenerateNonce

func GenerateNonce() (string, error)

GenerateNonce generates a nonce for the OAuth2 flow. The nonce is a base64 encoded

func IsNonceValid

func IsNonceValid(nonce string, noncePeriod int64) (bool, error)

IsNonceValid checks if a nonce is valid. A nonce is valid if it is a base64 encoded string

Types

type Engine

type Engine struct {
	// contains filtered or unexported fields
}

Engine is a structure that allows controller access to cryptographic functions. The intention is that this structure will be passed to the controller on creation and will validate that wrong parameters aren't passed to the functions.

func EngineFromAuthConfig

func EngineFromAuthConfig(authConfig *serverconfig.AuthConfig) (*Engine, error)

EngineFromAuthConfig creates a new crypto engine from an auth config

func NewEngine

func NewEngine(tokenKey string) *Engine

NewEngine creates a new crypto engine

func (*Engine) DecryptOAuthToken

func (e *Engine) DecryptOAuthToken(encToken string) (oauth2.Token, error)

DecryptOAuthToken decrypts an encrypted oauth token

func (*Engine) EncryptOAuthToken

func (e *Engine) EncryptOAuthToken(data []byte) ([]byte, error)

EncryptOAuthToken encrypts an oauth token
