The article Encrypting a tar file using openssl has the following line:
tar cvj ~/Projects/arc/ | openssl smime -encrypt -aes256 -binary -outform DEM public.pem | dd of=arc.bckp
we can use cat instead of dd at the end... but should we? which one is better to be used here - cat or dd? and why?
I've 'time'-ed both options and can't see any significant advantage...
