WebMay 24, 2024 · Due to the size of the nonce and the way that the counter mode encryption inside GCM works, files can be at most 64 GiB in size (minus a few bytes). That sounds like a lot, but for instance some games easily pass this kind of size. What is good is that you use streaming to encrypt / decrypt the files. You don't want to load large files into memory.
