How to use the fs-json-store-encryption-adapter.EncryptionAdapter function in fs-json-store-encryption-adapter

constructor(input: { key: Buffer, preset: EncryptionAdapterBundle.KeyBasedPreset }) {
        this.logger.info("constructor()");

        const encryptionAdapter = new EncryptionAdapterBundle.EncryptionAdapter(input);

        this.read = async (data: Buffer) => {
            this.logger.info(`read() buffer.length: ${data.length}`);

            const {header: {serialization}} = persistencePartsUtil.split(data);
            const decryptedData = await encryptionAdapter.read(data);

            if (serialization && serialization.type === "msgpack") {
                this.logger.verbose(`"msgpack.decode" start`);
                const decoded = msgpack.decode(decryptedData) as FsDb;
                this.logger.verbose(`"msgpack.decode" end`);
                return decoded;
            }

            const readableStream = bufferToStream(decryptedData);

export async function buildSettingsAdapter(
    {configStore}: Context,
    password: string,
): Promise {
    return new EncryptionAdapter(
        {password, preset: (await configStore.readExisting()).encryptionPreset},
        {keyDerivationCache: true, keyDerivationCacheLimit: 3},
    );
}
