Let’s Encrypt is a free, automated, and open certificate authority brought to you by the non-profit Internet Security Research Group (ISRG).
Security is probably one of the most significant concerns for both the shopper and the retailer during an online transaction. In reality an online transaction is probably more secure than a card transaction in a shop or conducted over the telephone or by fax, as the information transmitted online is highly encrypted using complicated logarithm combinations.
The RBS WorldPay payment system uses a combination of both established and innovative techniques to ensure the security and integrity of all sensitive data. Furthermore, our public web servers are certified by Thawte, a public Certificate Authority, ensuring that both the shopper and retailer can have confidence that nobody can impersonate RBS WorldPay to obtain confidential information.
The transfer of the purchase details from the retailers site to RBS Worldpay are encapsulated using our own encrypted and digitally-signed protocol. This uses a combination of standard methods such as PGP, RSA and MD5 to ensure that the information passed is secure and tamper-proof.
Security for the Shopper
Any communication between the shopper and RBS WorldPay is also encrypted to the maximum strength supported by the shopper's browser using TLS or 128 Bit SSL. Shopper are also protected from fraudulent use of their card in a "card not present" environment, by their card issuers. The card issuers provides the right for shopper to dispute a transaction if the goods/services did not arrive or if the card was used fraudulently.
Data storage on RBS WorldPay systems, and the communication between RBS WorldPay and the worldwide banking networks, is regularly audited by the banking authorities to ensure a secure transaction environment. We also ensure that we stay up-to-date with the latest versions of any third-party code we use, and continually review our own proprietary code.
