im looking for Android Java class that does the following 1. generate public and private encryption keys 2. get a base-64 version of the public key that can transmit to the server 3. accept a base-64 key from the server 4. use those keys to encryot and devrypt data to/from the server 5. a corresponding c# class for the server that does the same thing You dont need to write any network code, just those two classes one in java and the other one in c# .net 4.5.2 the java class should be like this public class RSAUtil { private PublicKey publicKey; private PrivateKey privateKey; public RSAUtil() { // generate public and private keys } public String getPublicKey() { // return base-64 version of the public key } public void setPublicKey(String base64PublicKey) { // set the public key from the server } public String encrypt(String plainText) { // use my private key to encryopt the data } public String decrypt(String encryptedText) { // use the servers public key to decrypt the data } } Need the corresponding class in C# .NET 4.5.2 that works with this java class.
