Subject: Upgrading Netscape 4.5 to full-strength crypto
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.
