RSA: How to generate private key in java and use it in C#? -


I saved as a 64-base encoded string in a file you want to generate a private key in Java, and then Encrypt some phrases using this saved file, in C # I know how to generate keys in Java and encode it with 64 base. My question is how do I use this key in C #? To save personal file text file Java code prototype: 

  KeyPair generator keyGen = KeyPairGenerator.getInstance ( "RSA"); RSakeyGenParameterSpec spec = New RSakeyGenParameterSpec (1024, RSakeyGenParameterSpec.F4); KeyGen.initialize (idea); Keypair keypair = keyGen.generateKeyPair (); Private Private Key = keyPair.getPrivate (); WriteToFile ("Personal", base 64. encode (keyPair.getPrivate). GetEncoded ()));

I C # would like to introduce the following function, but the private key can not find a way to make RSAParameters or RSACryptoServiceProvider 

  public static string DecryptData (string privateKey64Base, string data64Base) [making {using // using privateKey64Base // // byte RSAParameters up RSACryptoServiceProvider RSA] encryptedData = rsa.Encrypt (Convert.FromBase64String (data64Base);}  < / Pre>

Advice for your situation, since you are out of 8 (With Unjion writing PKCS # (keyPair.getPrivate ()). GetEncoded) include

This approach would be to get the private key in PRIVATEKEYBLOB format in the first place to use the utility side Java to use.

Alternatively, you can use decode BouncyCastle C # first of Org.BouncyCastle.Security.PrivateKeyFactory.CreateKey - Base64 course (see for example the read key You want to have it)

This past question is. As a result, to change the RSACryptoServiceProvider from the BC key object, answer:

Thirdly, you want to use a major star, e.g. PKCS # 12, which is a more standard (and safe) way to store private keys.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
