They are used to create cryptographic keys and to encrypt or sign data. It is strong and difficult to duplicate the same hash with unique inputs and is a one way function so revert is not possible. Most random number generators are hardware dependent or require specialized hardware. Random class has a lot of methods but nextint is the most popular. A cryptographically strong random number minimally complies with the statistical random number generator tests specified in fips 140 2 security requirements for cryptographic modules section 4 9 1 additionally securerandom must produce non deterministic output. The java keygenerator class javax crypto keygenerator is used to generate symmetric encryption keys a symmetric encryption key is a key that is used for both encryption and decryption of data by a symmetric encryption algorithm.
Java has had historic difficulty generating random numbers.
In this java keygenerator tutorial i will show you how to generate symmetric encryption keys. Random class has a lot of methods but nextint is the most popular. Java by principle is hardware independent and so uses pseudorandom number. Pseudo random functions which are not secure for cryptography usually use an internal state at the start the state is initialized by an initial seed when the next random number is generated it is calculated from the internal state using some computation or formula then the internal state of the pseudo random function is changed using some computation or formula. In the developer s world it is a common task to generate a random number in a situation like where we need to send an otp to a user for authentication or need to generate secure salt which will be used in cryptography etc. If you need a cryptographically secure random generator use java.
