Subject: Upgrading Netscape 4.5 to full-strength crypto (FW)

I haven't seen this mentioned anywhere, but the old perl script for
Netscape 4.0x that upgrades an export binary to use full-strength
crypto doesn't work on 4.5. They added some extra binary cruft that
also needs to be patched. A working script is in my sig. Enjoy.

Upgrade your export version Communicator 4.5 to full-strength crypto:]
#!/usr/bin/perl5 -0777pi           # Run on your "netscape" binary
s/KEY-BITS:.*?\0/$_=$&;y,a-z, ,;s, 512,2048,;s, {4}$,true,gm;$_/es;
s!\*:Q\xbf/q.{46}(.).{33}!substr($t=$&,54,ord$1)=~y,,\1,c;$t!egs
