|Introduction to Securing Data in Transit|
Secure data transfer methods are important, but the security can be broken without cryptanalysis if the computer at either end is insecure. Ensure that your computers and internal networks are secured.
Cryptanalysis can read most encryption methods, if the analyser is determined enough and wealthy enough to buy enough fancy hardware. If your information is worth enough, the most secure method of transfer might be 'sneaker-net' - a person with a floppy disk. If your information is that valuable, however, it's worth hiring a security expert to secure your networks. Take their advice.
