You could use popen() to execute http://gnupg.org or PGP...
It would be easier to recompile PHP, though, and performance on popen() is
going to suck.
You *might* be able to compile just the encryption module, and use
dl("mcrypt.so") in your PHP script to load it up rather than recompile all
of PHP, but again, it's going to be harder, and performance will suffer.
Compiling PHP the *second* time is *way* easier than the first time,
especially if you've saved your previous PHP source tree and all the other
source trees -- There's a file in the PHP source tree called config.status,
and some other config.* files, that "remember" what you did last time. So,
copy those somewhere safe, and then look at them.
You'll probably be able to copy config.status to config.zhu, and then edit
that to add --with-mcrypt (or whatever it is), and do:
chmod 755 config.zhu
./config.zhu

Subject: [PHP] encrypt and decrypt in standard PHP
> As the PHP manual indicates, we can use Mcrypt to do the encrypt and
decrypt work in PHP, but that needs to download the encrypt module and
recompile PHP. Is there any other way to encrypt and decrypt the string in
standard PHP4.0.4 without any extension module?
