title: JAVA: Using RSA and SHA-1 need to transmit data from client to server (Digital Signature)
body: <p>My requirement is to write a JAVA program which provides confidentiality and integrity of data transmission from a client to the server.</p>
  
  <p>For which am planning to use RSA and SHA-1 hash methods. Also need to set up a network connection between a client and a server and exchange the message. Server should verify the signature and check for the integrity.</p>
  
  <p>So I just wanted to know, is there any documents which would help me in writing it. </p>
  
  <p>Any help appreciated. Thanks </p>
