question: protected synchronized byte [ ] engineGenerateSeed ( int numBytes ) { byte [ ] myBytes ; if ( numBytes < 0 ) { throw new NegativeArraySizeException ( Integer . toString ( numBytes ) ) ; } if ( numBytes == 0 ) { return EmptyArray . BYTE ; } if ( myRandom == null ) { myRandom = new SHA1PRNG_SecureRandomImpl ( ) ; myRandom . engineSetSeed ( getRandomBytes ( DIGEST_LENGTH ) ) ; } myBytes = new byte [ numBytes ] ; myRandom . engineNextBytes ( myBytes ) ; return myBytes ; }
target:  Returns a required number of random bytes. <BR> The method overrides "engineGenerateSeed (int)" in class SecureRandomSpi. <BR>
