text: is there failsafe encryption? can you encrypt a cdr/rw with out it being broken you can make it unlikely to be broken using a strong cipher to encrypt the contents of a file, and then writing that fie to the cd. your passphrase is really the weak point of any cryptosystem. the data is secure from a brute force attack on the key, but an attacker could run a dictionary attack on your passphrase, and if it is at all weak, it will be cracked quickly.
