A third-party Golang package for Code42's Crashplan Forensic File Search (FFS) API
The goal of this Golang package is to provide an easy to use/integrate package for Code42's Crashplan FFS API within the Golang environment. There are two main functions that can be used within the package:
- GetAuthData
- GetFileEvents
These functions allow for someone to query the Crashplan FFS API and get the results returned in a Golang struct which can then be used for other purposes.
The GetAuthData is intended to get an API token for a user that will last for one (1) hour, which can then be used with the GetFileEvents function.
Arguments:
- uri - This is the URL which will provide the API token. (I believe it will always be: https://www.crashplan.com/c42api/v3/auth/jwt?useBody=true)
- username - The username of the account that has permissions to access the FFS API. (This must be an email address according to the API)
- password - The password of the account that is set as the username.
Returns:
- AuthData - Golang struct that contains the API token.
#AuthData struct structure

Data AuthToken
AuthToken
V3UserToken string
- error - Any errors.
The GetFileEvents is intended to gather all events for a passed query and return them as a Golang struct slice.
Arguments:
- authData - This is the Golang struct which is gotten from the GetAuthData function.
- ffsURI - This is the URL which actually hosts the FFS API. (See Code42 documentation for URI, default is https://forensicsearch-default.prod.ffs.us2.code42.com/forensic-search/queryservice/api/v1/)
- query - This is the properly formatted FFS Query struct which is what is actually executed against the Code42 Crashplan FFS API. (See documentation for how to properly format these queries.)
- Example JSON query (Returns all events within a 5 second delta)

Limitations:
Code42 Crashplan FFS API has limitations like most APIs, these limitations affect the GetFileEvents function:
- 120 Queries per minute, any additional queries will be dropped. (never actually bothered to test if/how this limit is actually enforced)
- 200,000 results returned per query. This limitation is kind of annoying to handle as there is no easy way to handle it. The API does not support paging and the only way to figure out how many results there is for a query is to first query, count, then if over 200,000 results, break up the query into smaller time increments and perform multiple queries to get all the results.
- The GetFileEvents function only supports the /v1/fileevent/export API endpoint currently. This has to do with how the highly limited functionality of the /v1/fileevent endpoint which isn't well documented.
