First page is collecting the data from user. And then send to another page to do another process. I am using OpenSSL certificate. But i want to send data using encryption method. I want to do,

1. Create a single string using data.
2. Encrypt that string using publickey.(I can use my public key got by OpenSSL)
3. Sending encrypted string to another page.
4. Decrypt that using private key. (I can use my private key got by OpenSSL)
5. Extract the string to get the variable clearly.

How can I do that? Please any one help me.
