Batch issuance support

To issue multiple credentials for a document, specify the keyOptions parameter in the issueDocument method. This allows to set the credentialPolicy and batchSize options.

Example usage:

try await wallet.issueDocument(docType: nil, scope: nil, identifier: identifier, keyOptions: KeyOptions(credentialPolicy: .oneTimeUse, batchSize: 10))

Additional method

/// Get the remaining presentations count for a document.	
/// Returns: Remaining presentations count (if one-time use policy was used to issue the document, otherwise nil)
public func getRemainingCredentialsCount(id: String) async throws -> Int?

SecureArea Protocol: Batch-Oriented API Changes

The SecureArea protocol was refactored to support batch-oriented key management and cryptographic operations. This change introduces methods for handling multiple keys at once. This affects implementors of the SecureArea protocol.

1. Batch Operations Added

• Key Creation:

  • createKeyBatch(id: String, keyOptions: KeyOptions?) async throws -> [CoseKey]
    • Creates a batch of keys and returns their public keys.

• Key Deletion:

  • deleteKeyBatch(id: String, startIndex: Int, batchSize: Int) async throws
    • Deletes a batch of keys starting from a specific index.
  • deleteKeyInfo(id: String) async throws
    • Deletes key metadata for a given batch.

• Signature and Key Agreement:

  • signature(id: String, index: Int, algorithm: SigningAlgorithm, dataToSign: Data, unlockData: Data?) async throws -> Data
    • Computes a signature using a specific key in the batch.
  • keyAgreement(id: String, index: Int, publicKey: CoseKey, unlockData: Data?) async throws -> SharedSecret
    • Performs key agreement with a specific key in the batch.

• Key Info:

  • getKeyBatchInfo(id: String) async throws -> KeyBatchInfo
    • Returns information about a batch of keys.

• Default Algorithm:

  • defaultSigningAlgorithm(ecCurve: CoseEcCurve) -> SigningAlgorithm
    • Returns the default signing algorithm for a given curve.

2. Single-Key Methods Removed

• Single-key methods createKey, deleteKey, and getKeyInfo were removed.
