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 generating a shortened callback Uniform Resource Locator (URL), comprising:
providing an original callback URL comprising a user-identification field and an encrypted-credential field;
removing a plurality of characters from the encrypted-credential field;
generating a filler key comprising the removed plurality of characters;
generating the shortened callback URL, the shortened callback URL specifying a URL that comprises the filler key; and
storing a decryption key.
2. The method of claim 1 , wherein the removed characters are removed based on a jump size, the jump size specifying a number of characters following a removed character that are not to be removed.
3. The method of claim 2 , wherein an indication of the jump size is included in the shortened callback URL.
4. The method of claim 1 , wherein a remaining plurality of unremoved characters is combined to form a broken payload.
5. The method of claim 4 , further comprising storing the broken payload.
6. The method of claim 1 , wherein the shortened callback URL comprises an identification associated with a particular user.
7. The method of claim 1 , wherein the shortened callback URL comprises a field identifying the decryption key associated with the encrypted-credential field.
8. A non-transitory, computer-readable medium comprising instructions that, when executed by a processor of a computing device, perform stages for generating a shortened callback Uniform Resource Locator (URL), the stages comprising:
providing an original callback URL comprising a user-identification field and an encrypted-credential field;
removing a plurality of characters from the encrypted-credential field;
generating a filler key comprising the removed plurality of characters;
generating the shortened callback URL, the shortened callback URL specifying a URL that comprises the filler key; and
storing a decryption key.
9. The non-transitory, computer-readable medium of claim 8 , wherein the removed characters are removed based on a jump size, the jump size specifying a number of characters following a removed character that are not to be removed.
10. The non-transitory, computer-readable medium of claim 8 , wherein an indication of the jump size is included in the shortened callback URL.
11. The non-transitory, computer-readable medium of claim 8 , wherein a remaining plurality of unremoved characters is combined to form a broken payload.
12. The non-transitory, computer-readable medium of claim 11 , the stages further comprising storing the broken payload.
13. The non-transitory, computer-readable medium of claim 8 , wherein the shortened callback URL comprises an identification associated with a particular user.
14. The non-transitory, computer-readable medium of claim 8 , wherein the shortened callback URL comprises a field identifying the decryption key associated with the encrypted-credential field.
15. A system for generating a shortened callback Uniform Resource Locator (URL), comprising:
a memory storage including a non-transitory, computer-readable medium comprising instructions; and
a computing device including a processor that executes the instructions to carry out stages comprising:
providing an original callback URL comprising a user-identification field and an encrypted-credential field;
removing a plurality of characters from the encrypted-credential field;
generating a filler key comprising the removed plurality of characters;
generating the shortened callback URL, the shortened callback URL specifying a URL that comprises the filler key; and
storing a decryption key.
16. The system of claim 15 , wherein the removed characters are removed based on a jump size, the jump size specifying a number of characters following a removed character that are not to be removed.
17. The system of claim 15 , wherein an indication of the jump size is included in the shortened callback URL.
18. The system of claim 15 , wherein a remaining plurality of unremoved characters is combined to form a broken payload.
19. The system of claim 15 , wherein the shortened callback URL comprises an identification associated with a particular user.
20. The system of claim 15 , wherein the shortened callback URL comprises a field identifying the decryption key associated with the encrypted-credential field.
