gnu.java.security.util.PRNG.nextBytes()
gnu.javax.crypto.prng.PBKDF2.nextBytes()
java.net.URL.nextBytes()
java.security.SecureRandom.nextBytes()
Generates a user-specified number of random bytes.
If a call to setSeed had not occurred previously, the first call to this method forces this SecureRandom object to seed itself. This self-seeding will not occur if setSeed was previously called. @param bytes the array to be filled in with random bytes.
java.util.Random.nextBytes()
Generates random bytes and places them into a user-supplied byte array. The number of random bytes produced is equal to the length of the byte array.
The method {@code nextBytes} is implemented by class {@code Random}as if by:
```
  {@code}public void nextBytes(byte[] bytes)  for (int i = 0; i < bytes.length; ) for (int rnd = nextInt(), n = Math.min(bytes.length - i, 4); n-- > 0; rnd >>= 8) bytes[i++] = (byte)rnd; }}
```
@param bytes the byte array to fill with random bytes @throws NullPointerException if the byte array is null @since 1.1
java.util.concurrent.ThreadLocalRandom.nextBytes()
org.apache.shiro.crypto.RandomNumberGenerator.nextBytes()
Generates a byte array of fixed length filled with random data, often useful for generating salts, initialization vectors or other seed data. The length is specified as a configuration value on the underlying implementation.
If you'd like per-invocation control the number of bytes generated, use the {@link #nextBytes(int) nextBytes(int)} method instead. @return a byte array of fixed length filled with random data. @see #nextBytes(int)
org.apache.shiro.crypto.SecureRandomNumberGenerator.nextBytes()
org.bouncycastle.crypto.prng.DigestRandomGenerator.nextBytes()
org.eclipse.jgit.junit.TestRng.nextBytes()
Get the next {@code cnt} bytes of random data. @param cnt number of random bytes to produce. @return array of {@code cnt} randomly generated bytes.
org.infinispan.lucene.testutils.RepeatableLongByteSequence.nextBytes()
@param buffer is going to be modified: a new series of bytes is going to be written into
