Which Algorithm is best, particularly as Scramdisk offers 8?
Scramdisk offers a choice of eight different encryption algorithms. I recommend Blowfiish. BestCrypt offers Twofish or GOST. GOST is an older Soviet Union program and rather slow. Twofish is one of several programs being evaluated for the Advanced Encryption Standard. So far it has withstood over 1,000 hours of intense crypto-analysis scrutiny without even approaching its limits. To ensure maximum security, you must take care over your choice of passphrase. This is the most likely weakness with most people. Always make it long. Remember, every extra character you enter makes a dictionary search for the right phrase twice as long. Both Scramdisk and BestCrypt ultimately limit the strength of the algorithm to 160 bits. This is because the hash program they use, SHA1, outputs a maximum of 160 bits. You will find that the passphrase input page for Scramdisk shows 4 lines for inputting your passphrase. Each line can hold a maximum of 40 characters. Thus a maximum of a 160 character passphra
