Hi Sahithi M,
1) Have you generated your public and private keys ?
Since, the sender is sending the files in encrypted format. We have generated both the keys and shared the public key with them. They have used our public key to encrypt the file and sending us.
2) Have you exchanged public keys with your sender?
Yes we have shared our public key with them for encryption.
So, if this is the case. Do we need to use the Decryption parameters in Receiver channel only right?. Please suggest.
