[16:40:57] <chris_99> Hi, i've been doing quite a bit of googling, but can't find the best solution as of yet, say i wanted to use sha256 hashes, to access a document, would you recommend i use that in the _id field, or should i create another field maybe for that hash? Alternatively there's not a way for mongodb to generate sha256 style hashes is there for documents? The reason I'm looking to use say sha256, is that the sha256 has will be

[16:40:57] <chris_99> used in a URL, and will be used to access a document (the document isn't sensitive, just don't want them to be easily guessable).
