What program can I use to compress (zip,rar...) and password protect files on my Android Froyo I was just sending a backup via mail to my Google account.

This backup contained readable information (csv format) from sensitive data.

Does anyone knows of a program to compress files (in .zip format, or .rar if necessary) on my Android phone (running Froyo), with a password protection used while compressing. 

That way I can compress/protect my data before sending it via email.

Thanks.
