Migrating to CC 10: Kotlin

See the common migration guide for changes that apply to all platforms.

Renames and Moves

1. CoreCryptoClient has been renamed to CoreCrypto.

2. historyClient(historySecret: HistorySecret) has been moved into CoreCrypto Companion functions.

3. The entire read-only API is now exposed on the CoreCrypto type, allowing data to be read without opening a transaction.

CoreCrypto Instantiation

1. The CoreCrypto constructor now takes a Database instance instead of a DatabaseKey and a path. To instantiate a database, call the Database.new() static method.

2. Deferred init is now the only way to instantiate CoreCrypto. Instead of calling deferredInit(), call the CoreCrypto constructor. As before, call mlsInit() in a transaction to initialize MLS.

Higher-Level Newtypes

CoreCryptoContext.getExternalSender() now returns an ExternalSenderKey object instead of a byte array. To access the raw bytes, call externalSenderKey.copyBytes().

Logging

1. We removed CoreCrypto.setLogger(logger: CoreCryptoLogger, level: CoreCryptoLogLevel), as logging is configured globally and not tied to a CoreCrypto instance. To set the log level, use the free function setMaxLogLevel(level: CoreCryptoLogLevel).

2. We renamed setLoggerOnly(logger: CoreCryptoLogger) to setLogger(logger: CoreCryptoLogger).

Other

1. Removed CoreCryptoFfi.reseedRng() and CoreCryptoFfi.randomBytes().
