Claim Text:
1. A system for computing a checksum for an online application, the system comprising: one or more hardware processors; and a machine-readable medium comprising instructions stored therein, which when executed by the processors, cause the processors to perform operations comprising: implementing the online application within a local application residing on a computing device using an online application code module included in the local application and written in a first programming language, wherein the online application is locally stored in the local application; receiving, at a checksum computer module within the local application and from the online application code module, one or more parameters associated with update information for the online application, the checksum compute module being written in a second programming language different from the first programming language, the checksum compute module being separate from the online application code module; determining, by the checksum compute module; a checksum associated with the online application for the online application code module based on the received parameters; providing the checksum to a memory, associated with the online application code module; verifying, by the online application code module, the checksum based on information received from a server or information stored in a local trusted cache; in response to a unsuccessful verification, executing the online application; and in response to an unsuccessful verification, requesting a new version of the online application code module.
