IOTA Identity - Account

The Account is an interface for creating and managing identities on the IOTA Tangle, handling publishing and secure storage automatically. It provides convenience functions for:

• Creating and publishing a new IOTA DID.
• Updating DID Document contents:
  • Verification Methods.
  • Verification Relationships.
  • Services.
• Managing private cryptographic keys securely.
• Signing credentials.
• Encrypting messages.

Account Creation

Creating an Account is done through the AccountBuilder.

let account: Account = Account::builder()
  .create_identity(IdentitySetup::default())
  .await?;

Update Operations

Updating a DID Document can be performed through the update_identity function on the Account. For example, adding a new verification method to the DID Document:

account
  .update_identity()
  .create_method()
  .content(MethodContent::GenerateEd25519)
  .fragment("my-next-key")
  .apply()
  .await?;

The above code generates a new Ed25519 keypair, writes it to Storage, embeds it in a new verification method, and publishes the updated DID Document to the Tangle.

See the IdentityUpdater for a list of provided update operations.
