Email notification system
Examples described herein include systems and methods for providing push notifications to a third-party application executing on a client device. An example can include encrypting user credentials, generating a callback Uniform Resource Locator (“URL”) with at least a portion of the encrypted credentials embedded into the URL, and requesting notifications from an email service to be provided at the callback URL. Upon receiving a notification at the callback URL, a system component can decrypt the credentials within the URL using a private key and log into the email account using those decrypted credentials. The system component can then generate a push notification based on any changes found in the email account and cause the notification to be delivered to the third-party application on the client device.
1. A method for receiving notifications at a client device, comprising:
requesting registration at a notification server;
providing, to the notification server, a hash of an email address associated with a user of the client device;
receiving, at the client device, a public key corresponding to a private key stored at the notification server, the public and private keys both being associated with the hashed email address;
encrypting, at the client device using the public key, user credentials associated with an email service;
transmitting the encrypted credentials to the notification server, wherein the notification server generates a callback Uniform Resource Locator (URL) that includes at least a portion of the encrypted credentials, and wherein the server instructs the email service to access the callback URL in response to a change in an email folder associated with the user; and
receiving a notification in response to the email service accessing the callback URL.
2. The method of claim 1 , further comprising accessing the email service in response to receiving the notification.
3. The method of claim 1 , wherein the notification is received at the client device from the notification server.
4. The method of claim 1 , wherein the notification is received from at least one intermediary server that receives the notification from the notification server.
5. The method of claim 1 , further comprising receiving a refreshed public key corresponding to a refreshed private key stored at the notification server.
6. The method of claim 1 , wherein the credentials comprise a certificate.
7. The method of claim 1 , wherein the credentials comprise an OAuth token.
8. A non-transitory, computer-readable medium comprising instructions that, when executed by a processor of a client device, perform stages for receiving email notifications, the stages comprising:
requesting registration at a notification server;
providing, to the notification server, a hash of an email address associated with a user of the client device;
receiving, at the client device, a public key corresponding to a private key stored at the notification server, the public and private keys both being associated with the hashed email address;
encrypting, at the client device using the public key, user credentials associated with an email service;
transmitting the encrypted credentials to the notification server, wherein the notification server generates a callback Uniform Resource Locator (URL) that includes at least a portion of the encrypted credentials, and wherein the server instructs the email service to access the callback URL in response to a change in an email folder associated with the user; and
receiving a notification in response to the email service accessing the callback URL.
9. The non-transitory, computer-readable medium of claim 8 , the stages further comprising accessing the email service in response to receiving the notification.
10. The non-transitory, computer-readable medium of claim 8 , wherein the notification is received at the client device from the notification server.
11. The non-transitory, computer-readable medium of claim 8 , wherein the notification is received from at least one intermediary server that receives the notification from the notification server.
12. The non-transitory, computer-readable medium of claim 8 , the stages further comprising receiving a refreshed public key corresponding to a refreshed private key stored at the notification server.
13. The non-transitory, computer-readable medium of claim 8 , wherein the credentials comprise a certificate.
14. The non-transitory, computer-readable medium of claim 8 , wherein the credentials comprise an OAuth token.
15. A system for receiving email notifications, comprising:
a memory storage including a non-transitory, computer-readable medium comprising instructions; and
a client device including a processor that executes the instructions to carry out stages comprising:
requesting registration at a notification server;
providing, to the notification server, a hash of an email address associated with a user of the client device;
receiving, at the client device, a public key corresponding to a private key stored at the notification server, the public and private keys both being associated with the hashed email address;
encrypting, at the client device using the public key, user credentials associated with an email service;
transmitting the encrypted credentials to the notification server, wherein the notification server generates a callback Uniform Resource Locator (URL) that includes at least a portion of the encrypted credentials, and wherein the server instructs the email service to access the callback URL in response to a change in an email folder associated with the user; and
receiving a notification in response to the email service accessing the callback URL.
16. The system of claim 15 , the stages further comprising accessing the email service in response to receiving the notification.
17. The system of claim 15 , wherein the notification is received at the client device from the notification server.
18. The system of claim 15 , wherein the notification is received from at least one intermediary server that receives the notification from the notification server.
19. The system of claim 15 , wherein the credentials comprise a certificate.
20. The system of claim 15 , wherein the credentials comprise an OAuth token.
