SHA-1 google blob app engine

I can see the SHA-1 of my blobs in the datastore viewer on live google app engine.

Is there a recommended way I can access the SHA-1 hash (or any other hash) of a blob programmatically in GAE?

Currently it is not possible to get the hash of the content of a blob stored in AppEngine's blobstore without using an external script to download it and hash it (a far from ideal solution).

Attaching a star to issue 2510 on the AppEngine issue tracker may help get the ability to hash blobs into AppEngine.

Do you mean the BlobKey? If so, just pass it to str(). Otherwise just generate a hash yourself with hashlib.

Have you looked at the module hashlib? It has a sha1() function.
