CMPP3.0 中CMPP_CONNECT 的AuthenticatorSource 算法 有何问题？

[sw245711601]

	private static byte[] getAuthenticatorSource(String Source_Addr,
            String Shared_Secret, String Timestamp) throws Exception{
		byte abyte2[] = new byte[100];
		byte abyte1[]={0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0};
		byte abyte3[] = new byte[16];
        MD5 md5 = new MD5();
        System.arraycopy(Source_Addr.getBytes(), 0, abyte2, 0, Source_Addr.length());
        int l = Source_Addr.length();
        System.arraycopy(abyte1, 0, abyte2, l,abyte1.length);
        l +=9;
        System.arraycopy(Shared_Secret.getBytes(), 0, abyte2, l, Shared_Secret.length());
        l +=6;
        System.arraycopy(Timestamp.getBytes(), 0, abyte2, l, Timestamp.length());
        md5.update(abyte2);
        md5.md5final(abyte3);
        return abyte3;
    }

为什么总是返回认证错 status 3 的错误? 知道的教小弟一声！
