comment How secure are passwords made of whole english sentences
Suppose you have 52 upper and lower case letter and 10 numbers. Then there are 62^8 possibilities to try to crack Kafka57. But for your sentence you can assume that you need say a directory with 5000 words. Then you need to try 5000^7 combinations, which is much more than 62^8. By the way Kafka57 seems to be pretty easy to attack by a wordlist attack with adding numbers...

comment How secure are passwords made of whole english sentences
In case of quotes: Do crackers actually use directories of whole quotes? For example if I cite Einstein like: "Two things are infinite: the universe and human stupidity; and I'm not sure about the universe." This seems to be unbreakable if one uses brute force trying every combination of characters. It also seems to be unbreakable if one tries to combine words from an english directory containing say 7000 words because then he should try 7000^16 combinations + applying word mangling rules. However using a directory of famous quotes, it should be cracked instantaneously
