I found Encrypting/Decrypting large files (.NET) which uses streams but it is not using AesGcm. The problem is that I can't find how to use AesGcm with streams. AesGcm.decrypt only accepts Byte in the ciphertext field, and AesManaged doesn't have CihperMode.GCM. Currently, decryption takes 4GB of ram when decrypting an 800MB file. Recommended security parameters for file encryption on disk. This is the optimal recommended usage for the specified GCM parameters when encrypting files of different size on disk. My goal is to optimize the key usage before there is a need to re-generate the key or the initialization vector (IV). Key Size: 256 bits; IV Size: 96 bits. You must own the original game discs just as with a real console. An emulator is basically (as far as the software that runs on it) a copy of the machine it's emulating and anything that's legal or illegal on a real console is legal or illegal on an emulator. Some emulators require the console's BIOS image which is usually ripped from a real. AES GCM always generates a nonce that is 16 bytes long, so calling.read(16) will get the nonce out of the encrypted file. Create a new AES decryption instance using the key and the nonce. Read the encrypted file bit-by-bit and decrypt, then output each part to the output file. After you choose the first file WinRAR then will start now choose to extract the file and WinRAR will then extract all files in the folder making 1.gcm or.iso file. If you extract a.gcm file then rename.gcm to.iso to burn. Hope I didn't confuse you.
How to open GCM file?
After double-clicking on the unknown file icon, the system should open it in the default software that supports it. If this does not happen, download and install the Dolphin software and then manually associate the file with it.
Step 1. Download and install Dolphin
If there is no Dolphin or similar software in the system that supports files with the GCM extension, you must first download and install it. Below you will find a list of the most-used applications that work with GCM. After going to the subpage of the program you will find a link to the developer's website, where you can safely download the software installer.

Step 2. Associate Dolphin with the GCM file extension
If the user already has one of the applications installed, the next step will be to associate it with the file extension GCM. This can be done in two ways - one is to manually edit the Windows Registry and HKEY_CLASSES_ROOT keys. The second way is simpler and definitely recommended for less advanced users.
- Right click on the unknown GCM file you want to open
- Select 'Open with' from the menu
- Click 'Choose another application'
- Click 'More applications'
- Click 'Find more applications on this PC' and indicate the installation location of the appropriate program
- Finally, select the 'Always use the selected program to open GCM files' option and confirm the whole operation.
Remember! Manually editing the system registry is only recommended for advanced users, and changes made to it without proper knowledge may result in damage to the system.

Step 3. Check out other possible problems related to GCM files.
Sometimes it happens that despite having the right application and the correct configuration, there are still problems with opening the GCM files. You should then find out what is the reason of the problem.
- Check if the GCM file is not infected - When the file GCM is infected with a virus or malware, it probably will not be able to be opened correctly. In this case, scan the GCM file and take the actions recommended by the antivirus program installed on the system. Most often it is disinfection or deletion of an infected file.
- Check if you, as the operating system user, have appropriate permissions to work with the file GCM
- Check if the icon is an element of the correct file but not only a shortcut to the location where the GCM file no longer exists.
- Check that the system has the necessary resources to run the Dolphin application and open the GCM file.
- Check if the file is complete - Sometimes it happens that the GCM file was not copied completely from the external Flash memory, or downloaded from the Internet. When the file is incomplete, it is not possible to open it correctly. In this case, please download or copy the file GCM again.

Step 4. Contact an IT expert
When all of the above methods have failed, it remains to contact an IT specialist or developers of the DOLPHIN program.
