问题是这样的,我们公司和其他公司会有一个数据的交互。当参数来到我们这里的时候需要进行各验证签名。就是验签,我们使用的是RSA方式,PHP语言来处理。但是对方公司使用JAVA来做,本来这不是问题,但是他们给的公钥和私钥都是16进制的。类似于如下

//十六进制公钥

30820276020100300d06092a864886f70d0101010500048202603082025c02010002818100845dfd18910026e2453710a2b2a4245ec0e019df083ac5e705cb02da01aff17acdd57daeef598c34d19d624d0e2315a14f6d11b9a8be46b4ba1a9b485d568c42a66ae3eb3b325aba537ed1dbf5fae3e1b74243f8f0f9b65ba3f72d41fe7a0354f401d4160b409c320c8591d2211c4a1e147276e4fdf2c488616872e67876875102030100010281804d0d8175b982c31fd876d382424776bc89be6a910073661cb3ac97be5c5915530d5b07ccbb9bff1808257bc1ab4715224fe007ff7191420b9682427e7f87102225e04b86a1f2edaf8e3be363d19cc57da43a5113f141d850b05119386dda4234e3cff902ae43402eef8106275484a82367c844920a96cfb0825e3667944e9339024100f21ca40df167a

 

我平日里和其他公司交互时候使用的公钥如下

//平日的公钥如

-----BEGIN PUBLIC KEY-----  MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC19+3Zkg8ko4S7XeAjGl2ps8dE  VGx2prFAAsq9OeNjvI4zbUG2iw7fvk02VZuilYyspB/MR1nMEWreVj21FdnN/szI  lC/stptlNMtmkZ28jv8QVvls8O2Zp97qDxSWbYwZFT1nmQVK1uSZV7wMEldWTSlF  cLuOXoFGGXndO9062QIDAQAB  

-----END PUBLIC KEY-----

 

问题来了我应该如何处理呢,先把16进制转换成普通的格式,我在网上查到的资料说是根本转换不了,但是对方公司也是用PHP可以做的。

跪求大神帮帮忙吧

你该搞明白他的公钥是怎么来的,你才好去解析

稳稳的河 | 园豆:4183 (老鸟四级) | 2015-10-16 16:52

import java.security.KeyPairGenerator; 他的公钥是通过这个JAVA程序生成的是RSA方法,在生成之后用了一个16进制的转换

你让对方把16进制转换的算法告诉你,你再按他们的规则把收到的字符串逆转回去就可以了。

厄  算法还关系语言么? 同一个算法,Java生成的公钥和PhP生成的公钥是一样的吧。。。

 

我也不懂,来学习。
