Dear all,

I've posted a new SSI blog entitled: "Protecting Sensitive Parts of Credentials with Cryptographically Enforceable Policies<https://blockchain.tno.nl/blog/protecting-sensitive-parts-of-credentials-with-cryptographically-enforceable-policies/>".
It has a proposal that enables credential issuers to encrypt sensitive parts of credentials in such a way that can only be decrypted by parties tha satisfy the issuer's policy (that was used to encrypt these parts). The blog motivates the need, introduces a high-level architecture, explains how it would work, and discusses some issues that need to be looked into.
