    I have some photos I want to send to a Windows user but I want a secure way of doing so. You can add a password to a zip file but I think thats a bit lame. Any suggestions?

    rsa encryption via cryptoloop? easy... on unix ;-) look it up on google. maybe you can do cryptoloop magic on windows via cygwin

    Why is a password lame? It's cross platform, so you don't have to find an encryption and decryption tool that works on both.

    Put it on a flash drive and hand the flash drive to your friend. Otherwise just use a password.

    If you want encryption, how about TrueCrypt (www.truecrypt.org)? There's a Mac, Linux, and Windows version, it's open-source and free, and containers created with any platform open on any platform.

    Or you could use GPG (openPGP) and encrypt the zip file that way. You can use GPG and PGP in the manner without keypairs (using a password instead - called a symmetric cipher)

    Because IIRC most forms of password protected ZIP use a weak algorithm...

    Most do, but some of the newer programs use AES (which is secure.)

    I *think* Stuffit uses AES, but I'm not sure.

    OS X has openssl built in, which is a command line tool for encryption. If the other user has a Mac or Linux based computer, or has downloaded openssl in Windows, they'll be able decrypt your file with the necessary password.

    You could also send a small Truecrypt container.
