我在哪里可以找到有关RSA公钥格式的文档？

RSA公钥,格式为OpenSSH:

SSH-RSA AAAAB3NzaC1yc2EAAAABJQAAAQB/nAmOjTmezNUDKYvEeIRf2YnwM9/uUG1d0BYsc8/tRtx + RGi7N2lUbp728MXGwdnL9od4cItzky/zVdLZE2cycOa18xBK9cOWmcKS0A8FYBxEQWJ/q9YVUgZbFKfYGaGQxsER + A0w/fX8ALuk78ktP31K69LcQgxIsl7rNzxsoOQKJ/CIxOGMMxczYTiEoLvQhapFQMs3FL96didKr/QbrfB1WT6s3838SEaXfgZvLef1YB2xmfhbT9OXFE3FXvh2UPBfN + ffE7iiayQf/2XR + 8j4N4bW30DiPtOQLGUrH1y5X/rpNZNlWW2 + jGIxqZtgWg7lTy3mXy5x836Sj/6L

格式化用于Secure Shell的相同公钥(RFC 4716 - 安全Shell(SSH)公钥文件格式):

---- BEGIN SSH2 PUBLIC KEY ----

---- END SSH2 PUBLIC KEY ----

格式化为RSA公钥的相同公钥(注意五个 -,没有空格):

-----BEGIN RSA PUBLIC KEY-----

base-64编码数据的十六进制转储:

00 00 00 07 73 73 68 2d 72 73 61 00 00 00 01 25 00 00 01 00 …

如何在两种公钥格式之间进行转换,一种格式为:

-----BEGIN PUBLIC KEY-----
...
-----END PUBLIC KEY-----

另一种格式是:

-----BEGIN RSA PUBLIC KEY-----
...
-----END RSA PUBLIC KEY-----

例如,我使用ssh-keygen命令生成了id_rsa/id_rsa.pub对,我使用以下方法计算了id_rsa中的公钥:

openssl rsa -in id_rsa -pubout -out pub2 

然后我再次使用以下方法从id_rsa.pub计算公钥:

ssh-keygen -f id_rsa.pub -e -m pem > pub1

pub1的内容是:

-----BEGIN RSA PUBLIC KEY-----
MIIBCgKCAQEA61BjmfXGEvWmegnBGSuS+rU9soUg2FnODva32D1AqhwdziwHINFa

而pub2的内容是:

-----BEGIN PUBLIC KEY-----

-----END PUBLIC KEY-----

根据我的理解,pub1和pub2包含相同的公钥信息,但它们的格式不同,我想知道如何在两种格式之间进行转换？任何人都可以向我展示两种格式的简明介绍吗？

我想使用RSA公钥加密.存储或检索私钥和公钥的最佳方法是什么？XML在这里是个好主意吗？

如何获得钥匙？

RSAParameters privateKey = RSA.ExportParameters(true);
RSAParameters publicKey = RSA.ExportParameters(false);

因为RSAParameters具有以下成员:D,DP,DQ,Exponent,InverseQ,Modulus,P,Q

哪一个是关键？

RFC中有一个RSA密钥:

我试过了jwk-to-pem:

还必须用"PUBLIC KEY"替换"RSA PUBLIC KEY".

该命令openssl rsa -inform PEM -pubin给出:
