Would someone be so kind and point me in the right direction for implementing encryption with asynchronous calls in ASP 2.0? I'd like to avoid paying for expensive third-party software. I'd like the web site user to pick an encryption key that only he or she knows. The only time the data should be in a decrypted state is in the client browser. The data should be encrypted in the database and while it is transmitted over the internet. Thank you in advance.
