The DataIdentity
class is a JavaScript implementation that provides a mechanism for creating, managing, and verifying digital identities on a blockchain. It leverages a secure element to generate cryptographic keys and sign data, ensuring the authenticity and integrity of the created identity.
- Identity Generation: Creates a new, random identity with a corresponding private key on a secure element.
- Payload Signing: Signs arbitrary payloads with the private key associated with the identity.
- Identity Publication: Publishes the identity on a blockchain using a smart contract.
- Identity Verification: Verifies the publication status of an identity.
- Identity Revocation: Revokes a previously published identity via a smart contract.
- Identity Disclosure: Reveals the identity, private key, signature, and payload.
- Self-Sovereign Identity (SSI): The class can be used to create and manage decentralized identities that are independent of central authorities.
- Authentication: The identity can serve as the foundation for an authentication system, for example, to access resources or services.
- Data Integrity: The signature of the payload can be used to ensure the integrity of data.
- Non-repudiation: The published identity can serve as proof of the creation of a specific data signature.
constructor(payload)
: Initializes a new instance of theDataIdentity
class with the given payload.#initSecureElement()
: Initializes the secure element and generates a new identity with a corresponding private key.async consensus()
: Signs the payload with the private key associated with the identity.async publish()
: Publishes the identity on a blockchain using a smart contract.async isPublishedAt()
: Checks if the identity is published on the blockchain.async revoke()
: Revokes a previously published identity via a smart contract.async isRevokedAt()
: Checks if the identity is revoked on the blockchain.async reveal()
: Returns the SSI and flushes the secure element.
