| When you use PayPal Subscriptions and Recurring Payments, your customers can purchase automatically recurring subscriptions from your website. StesCodes provides the easy way to integrate code for PayPal Subscriptions and Recurring Payments using Asp.net. StesCodes provides the source code for performing the website recurring payment from you own website. So inorder to setup recurring payment paypal the first thing is to get a paid service with paypal called website standard pro, after that the next step is to get the username, password and signature which you can see after you activated the API |

| The diagram shown above works by, when a customer uses credit card the first step is to get a token from the PayPal server. Once the token is received the next step is to get all the credit card details and the shipping details from customer. Then we need to pass all the information to PayPal through SOAP API. PayPal will send the response about the recurring with a profile ID. The profile ID is the key, so its better to store it somewhere may be in database. Because we are not doing direct payment but recurring, so we will receive two response from PayPal later. The first response is regarding the recurring profile creation completion and the second is the activation of the recurring profile. All these two response will be notified through a process called IPN where PayPal will send response to a particular url which we have to specify in the PayPal website settings and the IPN settings should be ON. The next step is to capture the IPN notification from our website which contains the profile id, amount and all details about the recurring payment, by using those details we can match the profile id with the profile id which we store before and process according to that, for example activation of the customer account etcs. |

| This algorithm follows the concept of data compression method, the below is the diagrammatic representation |

| Encryption is the process of transforming information or data using an algorithm to make it unreadable to anyone except those who implements it, usually referred to as a key. In our case in order to add more security we add with a constant number. The output of encryption process is called ciphertext. In order to make the unreadable encrypted text to eadable text we use a process called decryption which is a reverse process of encryption technique. Stescodes encryption / decryption algorithm which was developed for Asp.net, C# and VB.net. In stescodes algorithm it uses a algorithm technique which is called compression techniqe and shift operations, finally adding with a key value inorde to add more security. In the part of decryption stescodes uses the same technique in reverse order that is minus with the key value and decompress. |
