如何解决在mvc中使用公钥的数据加密2048 RSA算法
我想加密json数据 { “ urc”:“ 7718313198”, “ umc”:“ 101871”, “ ak”:“ asdfgh123456”, “ fname”:“ Biswajit”, “ lname”:“ Dolui”, “ email”:“ retailer001@giblvirtualmail.com”, “ phno”:“ 7718313198”, “ pin”:“ 712410” }
解决方法
我无法使用rsa算法2048在asp.net中加密长字符串 var csp = new RSACryptoServiceProvider(2048);
//how to get the private key
var privKey = csp.ExportParameters(true);
//and the public key ...
var pubKey = csp.ExportParameters(false);
//converting the public key into a string representation
string pubKeyString;
{
//we need some buffer
var sw = new System.IO.StringWriter();
//we need a serializer
var xs = new System.Xml.Serialization.XmlSerializer(typeof(RSAParameters));
//serialize the key into the stream
xs.Serialize(sw,pubKey);
//get the string from the stream
pubKeyString = sw.ToString();
}
//converting it back
{
//get a stream from the string
var sr = new System.IO.StringReader(pubKeyString);
//we need a deserializer
var xs = new System.Xml.Serialization.XmlSerializer(typeof(RSAParameters));
//get the object back from the stream
pubKey = (RSAParameters)xs.Deserialize(sr);
}
//conversion for the private key is no black magic either ... omitted
//we have a public key ... let's get a new csp and load that key
csp = new RSACryptoServiceProvider();
csp.ImportParameters(pubKey);
//we need some data to encrypt
var plainTextData = "{urc: 7718313198,umc: 101871,ak: asdfgh123456,fname: Biswajit,lname: Dolui,email: biswajitdoluicse@gmail.com,phno: 7718313198}";
//for encryption,always handle bytes...
var bytesPlainTextData = System.Text.Encoding.Unicode.GetBytes(plainTextData);
//apply pkcs#1.5 padding and encrypt our data
var bytesCypherText = csp.Encrypt(bytesPlainTextData,false);
//we might want a string representation of our cypher text... base64 will do
var cypherText = Convert.ToBase64String(bytesCypherText);
