what is "simple to use" in your opinion?

The Lifecycle Approach to Managing Security Policy

Managing application connectivity and security policies can be achieved more effectively when following a framework that automates repeatable processes and ensures that the right activities are performed in the right order.

All encryption encrypts plain text. What level of plain text encryption do you want?

Are you looking for partition based encryption?
http://www.truecrypt.tk/

Are you looking for file level encryption?
http://www.osborn-software.com/

Are you looking for whole disk encryption?
http://www.securstar.com/

Not sure of products for MAC.

Good Luck.

There is a nice product called bestcrypt.

All you need to do is create a file of any size you want, and then you can simply mount it whenever you want as a drive. You can put anything you want in it and it is encrypted on the fly. When you dismount the file (called container) no one can access the contents without the right password.

for windows there is a full-functioning trial available (30 days).

I'm assuming that "simple" = "no certificates to manage".

You need products that support Blowfish128, 3DES or AES standards. A password usually locks or unlocks the file - easy for users.

You can have different software on the Macs and the PCs, as long as they all *fully* support the same algorithm - i.e. both set to use 3DES or both set to use AES, etc.. The three standards above are fairly common and offer 128 bit strength. Well, almost, because the encryption is only as good as the password - make sure the passwords are strong too.

A search on download.com for "encryption" on OS X turned up a number of items, including the following that encrypts with AES:

A similar search for "AES encrypt" on Windows turned up a number of results, including the following:

http://www.download.com/EncryptIt/3000-2092-10194262.html?tag=lst-0-6

I've not used any of the above though. My personal preference is for GnuPG, but it's not too end-user-friendly!

For the nitpickers in the community ;o) , I'd better correct the above to read: "The three standards above are fairly common and offer *at least* 128 bit strength".

Blowfish128 is another name for 128 bit Blowfish, 3DES is 168 bit, and AES comes in 128 bit and 256 bit flavours.

what had in mind someway of typing text into a box and in a 2nd text would appear in the encryption so i could say paste it into msn, email or some other text  based thing, and send my message, the other person (with the key) would paste in the text in their program and read the uncoded message.

.. and PGP/GPG does this, except you can omit the copy&paste part on both sides ;-)
Hence PGP/GPG is simpler to use than you currently want it.

Since your needs are pretty simple, how about this?

Since it's java based, it will work with MAC and PC.

Good Luck
