I have no idea how to make blowfish work properly. I just did some basic stuff to encrypt and remember two strings in an ini, then read them and decrypt them.
On my pc it works normally, but after i sent the built mfa to my friend, he gets different encryption results, and it doesnt decrypt properly.

Is there some manual how to setup blowfish on the php page, so i can send encrypted string to decrypt?
And why doesnt it work properly on some pcs?
Is there maybe a better alternative to blowfish?
