That mmap() behavior is guaranteed by POSIX. It will be reliable on any compliant system.

Android has been derived from Linux and iOS from BSD if I'm not mistaken. I don't see why mmap should have issues but it never hurts to test. Of course you would need native code to use mmap. Java has also java.nio but I'm not sure you could use that for this use case.

@MaartenBodewes Thanks for your input. I'm trying to find another way without splitting up the plain data in several encrypted blocks. Celada's mmap() approach seems promising, since it is transparent to the calling functions. However I'm not sure how reliable this function is on Android / iOS devices.

You could always mmap() files and use the NaCL functions as is.

| May 26, 2015 at 2:29 | comment | added | Maarten Bodewes | The latter should be preferred. You should not process unauthenticated data. The only place where you should decrypt huge packages of data is where you 1) don't process the data immediately and 2) you cannot store the data in RAM. A good example would be file encryption/decryption. Even then it may pay off to split the plaintext into blocks or fragments. | |
