How do you get credit card numbers from your customers online in a safe secure and private way?

Credit card transactions are completed using a 128 Bit SSL Encrypted Secure Transaction, SSL uses public-key encryption to exchange a session key between the client and server; this session key is used to encrypt the http transaction (both request and response). Each transaction uses a different session key so that even if someone did manage to decrypt a transaction, that would not mean that they would have found the server's secret key; if they wanted to decrypt another transaction, they'd need to spend as much time and effort on the second transaction as they did on the first. Of course, they would have first have to have figured out some method of intercepting the transaction data in the first place, which is in itself extremely difficult.
