Thanks for the post, I found it really useful. At 03:52 PM 7/23/2006, Valdis Kletnieks put fingers to keyboard and wrote:
What chews up more entropy is the patterns *inside* each word. In English, the "next letter" is usually easy to predict (and therefor has little *effective* randomness or entropy).
I have a couple of questions. Does only English suffer from this problem, and would it make a stronger passphrase to use one non-English word in your phrase? -- Roger A.
