That's right, they "scramble" data and convert it into a numerical value.And no matter how long the input is, the output value is always of the same length.Hash functions are also referred to as hashing algorithms or message digest functions. MD5 implementations are not considered reliable for using it as the cryptographic checksums as the researchers have demonstrated the techniques for generating the MD5 collisions easily on the computers. 2) A hash function takes a message of fixed length and generates a code of variable length.

Q.23 The process by which malware avoids detection by changing the underlying code is known as polymorphism. Given an input, a hash function can produce multiple outputs. If the hash rate is too fast the difficulty level is increased. A high hash rate means more people and software machines are taking part in the mining process and as a result, the system is running smoothly.
