I just realised I had access to some OpenBSD gear: it's a "4.8
GENERIC.MP#411 amd64". My terminal settings was very confusing but after
I hard coded the pound sign as \xa3 it does produce the exact same hash
as my perl script:
bash-4.1$ cat bf.c
#include <pwd.h>
#include <unistd.h>
#include <stdio.h>
int main()
{
char password[] = "\xa3"; // Pound sign in ISO-8859-1
printf("BF Crypt: %s\n", crypt(password,
"$2a$05$/OK.fbVrR/bpIqNJ5ianF.$"));
return 0;
}
bash-4.1$ cc -o bf bf.c
bash-4.1$ ./bf
BF Crypt: $2a$05$/OK.fbVrR/bpIqNJ5ianF.Sa7shbm4.OzKpvFnX1pQLmQW96oUlCq
