If you need a cryptographically secure random generator use java. It is easy to calculate but challenging to retrieve original data. If you need a cryptographically secure random generator use java. 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. Java by principle is hardware independent and so uses pseudorandom number.
Crypto Random Generator Java. They are used to create cryptographic keys and to encrypt or sign data. It is easy to calculate but challenging to retrieve original data. 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.
