Example: SHA-256 Hash of a file API

This example shows the usage of SHA-256 Hash of a file API:

/* Compute the SHA-256 hash of a file */ 
 
if (!jdeSystemSHA256HashFile(huser, filename, sha256hash, &sha256hash_len)) { 
       jdePrintf(_J("SHA-256 hash computation failed\n")); 
       return 0; 
   }
