Assume you have secretfile.txt. E.g. (1) $ gzip secretfile.txt (2) $ gpg -c secretfile.txt.gz You get secretfile.txt.gz.gpg On the other box use, e.g. $ gpg --decrypt secretfile.txt.gz.gpg | gunzip | less Or if you first encrypt and then compress (you first did (2) and then (1)): $ gunzip -c secretfile.txt.gpg.gz | gpg --decrypt | less > So, I need a kind of simple C/C++ API which I can use to (de/en)crypt and > (un/)compress byte/char streams. Uhhh, why so complicated? Just use The Power of Shell. HTH, Mike - Linux-crypto: cryptography in and on the Linux system Archive: http://mail.nl.linux.org/linux-crypto/
