iOS 与 .net RSA加密 问题

Question

iOS客户端 生成的公钥密钥 格式为
MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC+lSTeGZH2QN2jz4Cgt8Wqk/8mU+RTpUOUxoOoXlag1RBx1Sx9RPhxBJlprk79p4M/aWW88vSlpCaVefVtXYDR0kpOe+VY1AL9AYWVxUh9JZ4NpmdkOf9nVcSrAEoydm0IhBlA/CzuSqWi5X0KaNwDaLwWb1LR8OXsXoJ8l8mWwwIDAQAB
 
怎样才能转换成 .net 能用的 XML格式的 公钥密钥
<RSAKeyValue><Modulus>vpUk3hmR9kDdo8+AoLfFqpP/JlPkU6VDlMaDqF5WoNUQcdUsfUT4cQSZaa5O/aeDP2llvPL0paQmlXn1bV2A0dJKTnvlWNQC/QGFlcVIfSWeDaZnZDn/Z1XEqwBKMnZtCIQZQPws7kqlouV9CmjcA2i8Fm9S0fDl7F6CfJfJlsM=</Modulus><Exponent>AQAB</Exponent></RSAKeyValue>求大神帮忙

Answer 1

有没有用 openssl 框架？可以直接从RSA类中取到exponent 和 modulus

Answer 2

用到了openssl    但是私钥不知道怎么弄
这是.net 的私钥 格式

Answer 3

你拿到 RSA 结构体了吧？rsa->e 试试看能不能取到 exponent

Answer 4

拿到了那该怎么拼成xml 而且我看私钥里边除了exponent 和 modulus 还有好多的东西

Answer 5

https://github.com/StCredZero/SCZ-BasicEncodingRules-iOS这是你想要的。

Answer 6

我的问题是拿到了服务器给的 <RSAKeyValue><Modulus>vpUk3hmR9kDdo8+AoLfFqpP/JlPkU6VDlMaDqF5WoNUQcdUsfUT4cQSZaa5O/aeDP2llvPL0paQmlXn1bV2A0dJKTnvlWNQC/QGFlcVIfSWeDaZnZDn/Z1XEqwBKMnZtCIQZQPws7kqlouV9CmjcA2i8Fm9S0fDl7F6CfJfJlsM=</Modulus><Exponent>AQAB</Exponent></RSAKeyValue>， 要转成iOS RSA加密用的公钥，在IOS8没问题，但是在iOS9就不能用了，求助啊！
