“刚才的那一张道符!”艾斯德斯惊疑不定的说道,不是她没见识,而是她身边的刘皓虽然是太乙金仙的修为,但是说到底也是第一次进入仙道位面,他的一身仙道法诀,武道法诀都是自己一路摸索上来的,所以就算是刘皓都没有见过真正仙道位面的道符。

“那是因为好吃嘛,果然,身居高位不管是在什么时代什么国家都是好,在你们国家明明只是再普通不过的食物,但是出自身居高位的人手里却完全不同的,难怪这么简单的食物都那么好吃了。”
但他刚走进小巷不到十步,后面迅速走上两人,重重拍了李醉肩膀一下,一回头,却见一只斗大的拳头向自己面门砸来,他来不及喊一声便被打晕在地,这时,一辆马车嘎地停在了小巷口。

这里可是仙都小洞天,而且已经隐匿于虚空当中,就算是大乘期强者也无法发现,所以根本不需要担心财不露白这一点。

前言

前不久移植了支付宝官方的SDK,以适用ASP.NET Core使用支付宝支付,但是最近有好几位用户反应在Linux下使用会出错,调试发现是RSA加密的错误,下面具体讲一讲。

RSA在.NET Core的改动

以前我们使用RSA加密主要是使用RSACryptoServiceProvider这个类,在.NET Core中也有这个类,但是这个类并不支持跨平台,所以如果你是用这个类来进行加/解密在windows上运行是完全没有错误的,但是只要你一放到Linux下就会出现异常。

查阅资料得知,要解决这个问题,需要改用 System.Security.Cryptography.RSA.Create() 工厂方法,使用它之后,在 Windows 上创建的是 System.Security.Cryptography.RSACng 的实例,在 Mac 与 Linux 上创建的是 System.Security.Cryptography.RSAOpenSsl 的实例,它们都继承自 System.Security.Cryptography.RSA 抽象类。

RSACng:

RSAOpenSsl :

RSA公钥/私钥说明

这里的RSA加密/解密主要是针对于由OpenSSL生成的公钥/私钥字符串。ssh-keygen -t rsa 命令生成的公钥私钥是不行的。

公钥/私钥生成

Windows&MAC_OSX可以使用有支付宝开发的RSA密钥生成工具:

使用此工具生成的时候一定要选择,PKCS1

下载地址:https://doc.open.alipay.com/docs/doc.htm?treeId=291&articleId=105971&docType=1

此外还可以使用OpenSSL工具命令来生成:https://doc.open.alipay.com/docs/doc.htm?articleId=106130&docType=1

.NET Core 中的使用

这里要讲一下RSA2算法。

什么是RSA2 ?RSA2 是在原来SHA1WithRSA签名算法的基础上,新增了支持SHA256WithRSA的签名算法。该算法比SHA1WithRSA有更强的安全能力。

算法名称 标准签名算法名称 备注
RSA2 SHA256WithRSA (强烈推荐使用),强制要求RSA密钥的长度至少为2048
RSA SHA1WithRSA 对RSA密钥的长度不限制,推荐使用2048位以上

签名的作用:保证数据完整性,机密性和发送方角色的不可抵赖性

这里来一发干货,我已经封装好的RSA/RSA2算法,支持加密/解密/签名/验证签名。
