Raaz.Hash.Sha1

Deprecated: SHA1 is broken. This module is here only for transition.

This module exposes combinators to compute the SHA1 hash and the associated HMAC for some common types.

The broken SHA1 cryptographic hash.

We already have a collision for SHA1: https://security.googleblog.com/2017/02/announcing-first-sha1-collision.html

While it does not yet rule out SHA1 for some specific tasks, there is no reason for its continual usage. This module is present only to facilitate the transition to a better hash. Use it assuming no security guarantees. Raaz will not try to optimise the implementations given here and will remove this module at some point of time. So do not rely on this for your software.
