Constants ¶
const ( // TripleDESKeyingOption1 means all three keys are independent TripleDESKeyingOption1 = 24 // TripleDESKeyingOption2 means K1 and K2 are independent, and K3 = K1 TripleDESKeyingOption2 = 16 // TripleDESKeyingOption3 means All three keys are identical, i.e. K1 = K2 = K3 TripleDESKeyingOption3 = 8 )
Variables ¶
var ( // ErrDivisionByZero returns because the input may cause division by zero ErrDivisionByZero = errors.New("division by zero") // ErrKeyLength returned because input key length is not qualified ErrKeyLength = errors.New("key length error, must be 16 or 24") )
