A library to generate and validate RFC6920 URIs

A library to generate and validate RFC6920 URIs

Naming Things with Hashes IETF RFC 6920 specifies both ni and nih schemes, and how they are generated and validated.

This library is composed by methods generate_ni (to generate a ni URI), generate_nih (to generate a nih URI), extract_digest (to get back both the digest and the hashing algorithm) and validate (to validate ni and nih URIs). Both generate_ni, generate_nih and validate understand both file paths and bytearray.

rfc6920.generate_nih(b'Hello World!') 
# It returns 'nih:sha-256;7f83-b165-7ff1-fc53-b92d-c181-48a1-d65d-fc2d-4b1f-a3d6-7728-4add-d200-126d-9069;d'

rfc6920.validate('nih:sha-256;7f83-b165-7ff1-fc53-b92d-c181-48a1-d65d-fc2d-4b1f-a3d6-7728-4add-d200-126d-9069;d', b'Hello World!')
