Examples of org.apache.shiro.util.SimpleByteSource

org.apache.shiro.util.SimpleByteSource
Very simple {@link ByteSource ByteSource} implementation that maintains an internal {@code byte[]} array and uses the{@link Hex Hex} and {@link Base64 Base64} codec classes to support the{@link #toHex() toHex()} and {@link #toBase64() toBase64()} implementations. @author Les Hazlewood @since 1.0

    public void testHashService() {
        DefaultHashService hashService = new DefaultHashService(); //默认算法SHA-512
        hashService.setHashAlgorithmName("SHA-512");
        hashService.setPrivateSalt(new SimpleByteSource("123")); //私盐，默认无
        hashService.setGeneratePublicSalt(true);//是否生成公盐，默认false
        hashService.setRandomNumberGenerator(new SecureRandomNumberGenerator());//用于生成公盐。默认就这个
        hashService.setHashIterations(1); //生成Hash值的迭代次数


        HashRequest request = new HashRequest.Builder()
