Selective Disclosure for W3C Data Integrity

Hi CCG'ers (VCWG bcc'd),

Today, we are announcing a selective disclosure capability for W3C
Data Integrity that is compatible with NIST-compliant cryptography. As
many of you know, the Data Integrity specification and a few
cryptosuites are being standardized in the W3C Verifiable Credentials

There has been a gap for a while now that made it not possible to meet
selective disclosure use cases using NIST compliant cryptography. This
is an important requirement that needs to be met for national
government and large enterprise use cases. This announcement now makes
it possible to meet those use cases.

A slide deck outlining this new capability is attached to this email
and provided in the link below:

There is a complete implementation of the mechanism available here,
that works with the Verifiable Credentials v2.0 work as well as the
ECDSA cryptosuite that is already adopted by the Working Group:

We look forward to feedback on the approach and interoperable
implementations as the work progresses in the public. We are also
happy to answer any questions or concerns that you might have
regarding the work.
