上面的第二次循环和第三次循环对应的值对应不上
//这是java代码
public static String encryptRsa(String arg5, String arg6) throws Exception {
      int v1;
      ByteArrayOutputStream v2;
      Cipher v0 = Cipher.getInstance("RSA/ECB/PKCS1Padding");
      v0.init(1, WeiboIdTask.getPublicKey(arg6));
      arg6 = "UTF-8";
      byte[] v5 = arg5.getBytes(arg6);
      try {
         v2 = new ByteArrayOutputStream();
         v1 = 0;
      }
      catch(Throwable v5_1) {
         v2 = ((ByteArrayOutputStream)v1);
         goto label_36;
      }

      while(true) {
         int v3 = 117;
         try {
            v3 = WeiboIdTask.splite(v5, v1, v3);
            if(v3 != -1) {
                  v2.write(v0.doFinal(v5, v1, v3));
                  v1 += v3;
                  continue;
            }

            v2.flush();
            String v0_1 = new String(Base64.encodebyte(v2.toByteArray()), arg6);
            break;
         }

总长度360
第一次循环是取前0-117
第二次循环是取117-234
第三次循环是取234-351
第四次循环是取351-360
然后分段加密拼接，FD抓包返回回来的密文长度是684
我自己分段加密拼接是688
不知道是不是这个循环我的逻辑搞错了，求教大神

RSA分段加密,直接调用JS写个循环加密,或者易语言base64解码后拼接再base64编码

这种问题通常要定制区。
