Set the key used in encryption
#include <stdlib.h> void setkey( const char *__key );
- A 64-character array of binary values (numeric 0 or 1).
Use the -l c option to qcc to link against this library. This library is usually included automatically.
This function is in libc.a, but not in libc.so (in order to save space).
The setkey() function allows limited access to the NBS Data Encryption Standard (DES) algorithm itself. It derives a 56-bit key from the given __key by dividing the array into groups of 8 and ignoring the last bit in each group.
