I have 2 methods to generate 2 different data and need to save them in one encrypted file.
Can I achieve this by adding encrypted stringA + encrypted stringB, then decrypt them later?
Or
I have to encrpt stringA -> save as file -> read the file & decrypt to stringA -> stringA + stringB -> encrypt ?
NB, I am using Rijndael(AES) and someone suggested using customerized stream, will it work?
Any thoughts? Many thanks~
