- Brute force attack- the program tries different combinations of characters until it finds a match. There are some free tools that do this for you and it usually takes a few minutes to find a windows password. Using characters like @, #, $, ! and other charaters and using upper and lower case letters makes it harder to crack.
- hash function- a way a message is encoded. if the message is changed the hash value will change. no 2 messages should have the same hash value. an example of a hash is 04f4845db75583433484181425cad72a, the message in english is iminyourcomputerstealingyourdata, e0b248e678bde43a77fc7cf10deb3f58 in english the message is iminyourcomputerstealingyoudata. there was a small change there in the original message yet a huge change in the hash value.
