compiler warning and "one last thing"

[homonto]

Hi, I started using your library for my project and there are 2 issues:

• compiler warning:

warning: ISO C++ forbids converting a string constant to 'char*' [-Wwrite-strings]
   char*  key = "mykey";

when my assignment looks like this:

  char*  key = "mykey";
  cipher->setKey(key);

Program compiles but warnings are there - I am sure cleaner compilation would be better ;-)
Changing to:
char* key = (char*)"mykey";
solves the issue but the same is with regards to hardcoded declaration in Cipher.cpp

void Cipher::setKey(char * key) {
  privateCipherKey = key;
}

• "one last thing": when text is declared as a key, it is visible in the output binary file - is there any way of assigning the key without seeing it in the bin file?

Btw: thank you for your great job!

@homonto One possible solution to storing the key in the (ELF) binary as a non-string (i.e. not be visible in the .rodata section) is to statically -- and painfully -- initialize the elements of an array of, say, type float to numerical values corresponding to the (ASCII) characters of the key. Then, at runtime, you could malloc() a char * buffer and initialize its elements (via a loop) using typecasts of the corresponding elements in the FP array. This dynamically allocated char * buffer becomes C-string key. Does this make sense?
