Calculate the key space for 128-bit keys and compare that to the key space for 10-character passwords (lower case English alphabetic, upper case English alphabetic, 10 digits and 14 special characters are allowed). How many characters does a password following the above rules must have to achieve the same or better security as 128-bit random keys if the passwords would be chosen randomly?

Cryptography

Cryptography is a term used in computer science to describe secure information and communication techniques that transform messages in difficult-to-decipher ways using mathematical concepts and a set of rule-based calculations known as algorithms.
