New European standards for the EU Digital Identity Wallet mandates support for a Hardware Security Module (HSM). This module is able to perform important cryptographic operations providing very strong security and privacy protection for a user. The EU Digital Identity Wallet is typically an application the user installs on an iOS or Android mobile device allowing the user to manage their government and commercial issued verifiable credentials. Fulfilling the requirements of the EU Digital Identity Wallet, this paper outlines how an existing Digital Identity Wallet can be enhanced to leverage a HSM, examining both inbuilt and external implementations. This paper presents a compatible matrix by
analyzing the existing credential standards and different HSM cryptographic capabilities.
