Use this program. It translates to/from EISAIDs.
#include <sys/param.h>
#include <stdio.h>
int
main(int argc, char** argv)
{
u_int32_t id;
if (argc != 2)
exit(1);
if (!strncmp(argv[1], "0x", 2)) {
id = strtol(argv[1] + 2, NULL, 16);
#define B0(n) (((n) >> 0) & 0xff)
#define B1(n) (((n) >> 8) & 0xff)
#define B2(n) (((n) >> 16) & 0xff)
#define B3(n) (((n) >> 24) & 0xff)
printf("%c%c%c%02x%02x\n",
((B0(id) & 0x7c) >> 2) + 64,
(((B0(id) & 0x03) << 3) | ((B1(id) & 0xe0) >> 5)) + 64,
(B1(id) & 0x1f) + 64, B2(id), B3(id));
} else {
#define PNP_HEXTONUM(c) ((c) >= 'a' \
? (c) - 'a' + 10 \
: ((c) >= 'A' \
? (c) - 'A' + 10 \
: (c) - '0'))
#define PNP_EISAID(s) \
((((s[0] - '@') & 0x1f) << 2) \
