Truvera is built on W3C open standards, it ensures that users can store their credentials on any digital wallet that adheres to these standards and that any stakeholder, wherever they are in the world, can verify the authenticity of the data as long as their verification system adheres to these standards. If there is a standard for which you would like further clarification or support, please contact us.

Credential documents are stored encrypted with ECDH-ES+A256KW using x25519 key agreement keys. The index is encrypted with searchable encryption.
Other data is stored on RDS and S3 using AWS's default encryption.
Queued messages are encrypted per the DIDComm Message packing.
Our credential library uses Arkworks Math Library for signing credentials and generating proofs.
We also use Libsodium for encryption in communication and storage.
Truvera believes that credentials are most useful when they are interoperable across service providers. Our W3C compliant credential format is designed for maximum interoperability. Our anonymous credential format adheres to many W3C standards, but are designed for maximum privacy protection. We also leverage standards from OpenID, IETF, DIF, and related organizations.
