I got PGP 262 off MIT.

The file was PGP262si.tar

Is this the international version with week crypto? os is it the US version?

Actually, the file you got was pgp262s.tar.gz (or something equivalent.) Inside this tarfile you found pgp262si.tar, which is the Source, Internal tarfile. It is not am international version; it is the US version. Also, neither the US version nor any international versions have weak crypto. Enjoy! -derek
