Data Integrity Proofs format for Verifiable Credentials

The Verifiable Credential Data Model does not, by itself, specifies how the proof is encoded and delivered with the credential data. This library provides the Data Integrity proof format, where the proof is defined through Data Integrity Crypto Suites and embedded to the VC document using the security#proof property.
