sha

Check and get file hashes (using any algorithm)

Installation

$ pip install sha

API

check(fileName, expected, [options,] cb) / checkSync(filename, expected, [options])

Asynchronously check that fileName has a "hash" of expected. The callback will be called with either null or an error (indicating that they did not match).

Options:

• algorithm: defaults to sha1 and can be any of the algorithms supported by crypto.createHash

get(fileName, [options,] cb) / getSync(filename, [options])

Asynchronously get the "hash" of fileName. The callback will be called with an optional error object and the (lower cased) hex digest of the hash.

Options:

• algorithm: defaults to sha1 and can be any of the algorithms supported by crypto.createHash

stream(expected, [options])

Check the hash of a stream without ever buffering it. This is a pass through stream so you can do things like:
