/*
* 1. 创建根证书私钥
* openssl genrsa -out root-key.key 1024
* 2. 创建根证书请求文件
* openssl req -new -out root-req.csr -key root-key.key -keyform PEM
* 3. 自签根证书
* openssl x509 -req -extfile d:\test\openssl.cnf -extensions v3_req -in root-req.csr -out root-cert.cer -signkey root-key.key -CAcreateserial -days 3650
* 4. 导出p12（pfx）格式证书（包含公、私钥） （p12：PKCS#12，PFX: Personal Information Exchange）
* openssl pkcs12 -export -clcerts -in root-cert.cer -inkey root-key.key -out root.p12
* 5. 从.p12文件中提取私钥
* X509Certificate2 x509 = new X509Certificate2(p12-file, password, X509KeyStorageFlags.Exportable);
* var publicKey = x509.PublicKey.Key.ToXmlString(false);

* p, q [P = p, Q = q]
* n=p*q [Modulus = n]
* φ(n)=(p-1)*(q-1)
* ed = 1 mod φ(n) [Exponent = e, D = d][e称为指数，用作公钥；d是e模φ(n)的逆元，用作私钥][加密：c = m ^ e mod n，解密：c ^ d mod n]
* DP=d mod p-1
* DQ=d mod q-1
* q* InverseQ=1 mod p [InverseQ是q模p的逆元]
