Hi,


We are trying to include a license file with our software. We want to decrypt it at our end. The client should not be able to decrypt it. If he decrypts it,changes it and encrypts it back again by some means, the software should not be able read it again.
What do you think I should use here? Have been reading up on public/private algos. and DH key exchange.


bye,
Mohan

You could encrypt it and also do an MD5 checksum. If it is changed, the checksum will change.
