    Functions

    func Checksum

    func Checksum(key []byte, usage uint32, data []byte) ([]byte, error)

      Checksum returns a hash of the data in accordance with RFC 4757

      func DecryptData

      func DecryptData(key, data []byte, e etype.EType) ([]byte, error)

        DecryptData decrypts the data provided using the methods specific to the etype provided as defined in RFC 4757.

        func DecryptMessage

        func DecryptMessage(key, data []byte, usage uint32, export bool, e etype.EType) ([]byte, error)

          DecryptMessage decrypts the message provided using the methods specific to the etype provided as defined in RFC 4757. The integrity of the message is also verified.

          func EncryptData

          func EncryptData(key, data []byte, e etype.EType) ([]byte, error)

            EncryptData encrypts the data provided using methods specific to the etype provided as defined in RFC 4757.

            func EncryptMessage

            func EncryptMessage(key, data []byte, usage uint32, export bool, e etype.EType) ([]byte, error)

              EncryptMessage encrypts the message provided using the methods specific to the etype provided as defined in RFC 4757. The encrypted data is concatenated with its RC4 header containing integrity checksum and confounder to create an encrypted message.

              func HMAC

              func HMAC(key []byte, data []byte) []byte

                HMAC returns a keyed MD5 checksum of the data

                func StringToKey

                func StringToKey(secret string) ([]byte, error)

                  StringToKey returns a key derived from the string provided according to the definition in RFC 4757.

                  func UsageToMSMsgType

                  func UsageToMSMsgType(usage uint32) []byte

                    UsageToMSMsgType converts Kerberos key usage numbers to Microsoft message type encoded as a little-endian four byte slice.

                    func VerifyIntegrity

                    func VerifyIntegrity(key, pt, data []byte, e etype.EType) bool

                      VerifyIntegrity checks the integrity checksum of the data matches that calculated from the decrypted data.
