怎么把RSA公钥的大整数转为OpenSSH那种字符串？
我用sun.security.rsa.RSAPrivateCrtKeyImpl生成的私钥是：

Sun RSA private CRT key, 1024 bits
  modulus: 138366379149556651529264271167627776457858687036310253186931869304419603614951358029547428616757746198297697875913048009038184919740987891480058872914394404915587279803233281027437510321771042949607120103195234015711071571988324336148543386523834345645243818986713709872730288332630296741272814978967784227069

而需要的格式和OpenSSH的格式一直，类似：

-----BEGIN RSA PRIVATE KEY-----

-----END RSA PRIVATE KEY-----

我想知道这两个形式是如何转换的？？

------解决方案--------------------
帮你顶顶吧 复杂的加密 看有高手来不
------解决方案--------------------
这个太高深不会，期待高手
------解决方案--------------------
留个印记 记得以后来补习
------解决方案--------------------
看看rsa加密算法。这个不是简单就转换成的，何况加密都有现成的程序模块了，还用费这个脑筋么？
------解决方案--------------------
帮你顶一下，我也正要知道这个，期待高手
------解决方案--------------------
期待高手正解 rsa 哈哈 非对称加密算法 经典
------解决方案--------------------
感觉是进制的问题。。
你把modulus: 138366379149556651529264271167627776457858687036310253186931869304419603614951358029547428616757746198297697875913048009038184919740987891480058872914394404915587279803233281027437510321771042949607120103195234015711071571988324336148543386523834345645243818986713709872730288332630296741272814978967784227069 
变成16进制显示就可以了 应该
