Hello All,

I want to Decrypt a string using private key that has been provided. I have started coding recently in C# any help with a code will be highly appreciated.

What I have tried:

I am completely new to this so I don't even know where to start from I have read about the private and public keys, certificates and even wrote a program to encrypt and decrypt but that program only decrypt the string that I encrypted from the same program.

Without knowing the encryption method that has been used this is impossible to answer.

You could change your program to also allow inputs of an encrypted string and of the private key and then use the key to decrypt the string.
