You can use it like this below

//Creating MasterKey
            val masterKey = MasterKey.Builder(context)
                .setKeyScheme(MasterKey.KeyScheme.AES256_GCM)
                .build()

            val fileToRead = "your_file_name.txt"
            val encryptedFile = EncryptedFile.Builder(context,
                File(context.filesDir, fileToRead),
                masterKey,
                EncryptedFile.FileEncryptionScheme.AES256_GCM_HKDF_4KB
            ).build()
