为什么 PHP 和 Java 对于 SHA1withRSA 签名的结果不一致

[unbeau]

求大神解答，万分感谢

PHP 源码：

$xmldata = '<?xml version="1.0" encoding="GBK"?>
<AIPG>
<INFO>
<TRX_CODE>310001</TRX_CODE>
<VERSION>05</VERSION>
<DATA_TYPE>2</DATA_TYPE>
<LEVEL>5</LEVEL>
<MERCHANT_ID>200604000012282</MERCHANT_ID>
<USER_NAME>20060400001228204</USER_NAME>
<USER_PASS>111111</USER_PASS>
<REQ_SN>200604000012282-1526894131128</REQ_SN>

</INFO>
<FAGRA>
<MERCHANT_ID>200604000012282</MERCHANT_ID>
<BANK_CODE>0104</BANK_CODE>
<ACCOUNT_TYPE>00</ACCOUNT_TYPE>
<ACCOUNT_NO>62284811119386045775</ACCOUNT_NO>
<ACCOUNT_NAME>小虎</ACCOUNT_NAME>

<TEL>187621116887</TEL>
<REMARK>单笔实时身份验证-备注字段</REMARK>
</FAGRA>
</AIPG>';

openssl_pkcs12_read(file_get_contents('3.p12'), $certs, '111111');
$signature = '';
openssl_sign($xmldata, $signature, $certs['pkey']);
$sign = bin2hex($signature);



java 源码：

Signature sign = Signature.getInstance("SHA1withRSA");
sign.initSign(prikey);
sign.update(msg.getBytes(encoding));
byte signed[] = sign.sign();
byte sign_asc[] = new byte[signed.length * 2];

Hex2Ascii(signed.length, signed, sign_asc);
signedStr = new String(sign_asc);

求大神帮助 java 的签名是正确的

你同一种语言测试两次也是不一样的

RSA 是不是要分段加解密啊？

已经解决了，是加密的字符创多了个空格。。。
