file encryption and integrity check

[Francesco Turco]

hello,

i am very new with gnupg and cryptography in general.

i'd like to know if gnupg is a good choice for encrypting files with a 
password and if it is possible to check if an encrypted file is 
corrupted or not (integrity check). my goal is to burn some files on cds 
and protect them both from other people and from physical corruption of 
the media.

thanks.
