Build a MD4 plugin using Linux system library and PARI's function interface. (Linux solution)
<lang C>#include <pari/pari.h>
#include <openssl/md4.h>
#define HEX(x) (((x) < 10)? (x)+'0': (x)-10+'a')
/*
* PARI/GP func: MD4 hash
*
* gp code: install("plug_md4", "s", "MD4", "<library path>");
*/
GEN plug_md4(char *text)
{
char md[MD4_DIGEST_LENGTH];
char hash[sizeof(md) * 2 + 1];
int i;
MD4((unsigned char*)text, strlen(text), (unsigned char*)md);
for (i = 0; i < sizeof(md); i++) {
hash[i+i] = HEX((md[i] >> 4) & 0x0f);
hash[i+i+1] = HEX(md[i] & 0x0f);
}
hash[sizeof(md) * 2] = 0;
return strtoGENstr(hash);
}</lang>
Compile with: gcc -Wall -O2 -fPIC -shared md4.c -o libmd4.so -lcrypt -lpari
Load plugin from your home directory into PARI:
<lang parigp>install("plug_md4", "s", "MD4", "~/libmd4.so");
MD4("Rosetta Code") </lang>
