Android Question B4XCipher memory use

[a n g l o]

hi,
after many tests on different devices, i get the impression that :
B4XCipher.Encrypt memory usage is the size of the byte array that passed (and returned).
B4XCipher.Decrypt memory usage is the size of the byte array that passed (and returned) * 2 .

since it's a library (B4XEncryption) and not a class module, i can't check the source to find out if the algorithm really needs that double amount in Decrypt, or it's a thing that can be corrected/improved.

thank you

Does your app crash or is there a memory leak which causes your device to have a out of memory problem? If not: Just ignore it...

What is the data size?

any size 10-50 MB (that's was the range in my tests)

It will probably be quite slow to decrypt such large data. Consider using SQLCipher instead.

i 'm not familiar with it. i may look it up.
speed/time is not a problem/factor here.
Thank you
