Can PGP and GPG co-exist?

Last Modified: 2010-04-11
I have a machine running PGP, but I need to use it to test GPG or TrueCrypt.

Can these programs co-exist?

I need to decided between GPG and TrueCrypt.  Is either just as safe to co-exist with PGP, or is one better than the other?

Also, PGP on my Virtual Private Server was generating errors because it was not able to lock the memory since it was a shared system. And PGP error messages advised me to uninstall if from the system.

Will I have a similar problem with either GPG or TrueCrypt?  I don't actually need to provide as good protection as PGP, which I use for my source code.  I just want it nearly impossible to hack.

Is there another way to encrypt with NON public key / private key software, that's free?

Something that's not so  rebust as GPG but still not simple to break through?  I really don't want to spend the time doing trial and error on my web hosts.

What a pain for something that will be published shortly thereafter anyway.

What exactly do you want to encrypt? A bunch of local files? A complete partition? Email in transit? Web site access?
And which OS does the server run?

I run XP Pro and Vista, and want to encrypt a website in transit and database of names, up to a Virtual Private Server.

Crypto Expert Lite did what I needed, but was too slow to encrypt.  I don't need protection that will cause me delays.  I may just end up using WinZip with a password.

Or may consider using GPG on the VPS.  I ran into problems with PGP on a VPS because of the insecurity of shared memory, and PGP generated errors saying it should be uninstalled.  I guess I could try GPG but expect the same thing.
