Compile-time string encryption

Question

I don\'t want reverse-engineers to read the plain-text of hardcoded strings in my application. The trivial solution for this is using a simple XOR-Encryption. The problem is

Answer 1

I think you have to do something like what is done when using gettext (i18n) :

• use a macro like your CRYPT.
• use a parser that will crypt string when it finds CRYPT.
• write a function that decrypt, called by your macro.

For gettext, you use the _() macro that is used to generate the i18ned string dictionnary and that call the gettext function.

By the way, you have to manage i18n too :), you will need something like :

_CRYPT_()
_CRYPT_I18N_()

You have to manage that with your build system to make it maintenable. I do that with gettext...
