Re: testing tool to test the encryption of licence key
Will the license key be sent over an insecure connection or stored in an insecure media?
If so, your encryption algorithm should be strong enough so that it is not possible to guess/ determine your license key. The license key should be long and structurally complex (e.g. with combination of alphabets, numbers, special characters) so that it will take an inordinately long time, on average, in trying all possible permutations one-by-one.
