squueze command and compact flash card ??

How to encrypt files?

I have some text files that I would like to encrypt. What methods/programs are available on Centos4 to do this? Also, is there an option with gzip that I am missing or does it not natively contain encryption capabilities?

Thanks,

nameserver x.x.x.x
