The following are Jave code examples for showing how to use setSeed of the java.security.SecureRandom class. You can vote up the examples you like. Your votes will be used in our system to get more good examples. By default Java doesn’t have any utility which creates strong long random password. Here we have created detailed tutorial on how to generate Strong Random Password using java.security.SecureRandom API.

This class provides a cryptographically strong random number generator (RNG).

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. Therefore any seed material passed to a SecureRandom object must be unpredictable, and all SecureRandom output sequences must be cryptographically strong, as described in RFC 1750: Randomness Recommendations for Security.

A caller obtains a SecureRandom instance via the no-argument constructor or one of the getInstance methods:

Java Command Line Generate Securerandom Key Code

Many SecureRandom implementations are in the form of a pseudo-random number generator (PRNG), which means they use a deterministic algorithm to produce a pseudo-random sequence from a true random seed. Other implementations may produce true random numbers, and yet others may use a combination of both techniques.

Typical callers of SecureRandom invoke the following methods to retrieve random bytes:

Callers may also invoke the generateSeed method to generate a given number of seed bytes (to seed other random number generators, for example): Note: Depending on the implementation, the generateSeed and nextBytes Aix generate ssh host keys. methods may block as entropy is being gathered, for example, if they need to read from /dev/random on various unix-like operating systems.
