Untested, but should work according to the docs:
hm = hmac.new('key', msg='message', digestmod=lambda: hashlib.new('ripemd160'))

HMAC with RIPEMD-160

2008-12-21 Thread Kless 
Is there any way of use HMAC with RIPEMD-160?

Since that to create a ripemd-160 hash there is to use:
h = hashlib.new('ripemd160')
it looks that isn't possible

For HMAC-SHA256 would be:
-
import hashlib
import hmac

hm = hmac.new('key', msg='message', digestmod=hashlib.sha256)
-
