Hi,
I saw in one of the mock tests as 'session key' is used in encrypttion,
I know about 'public key' and 'private key', but I do not know about the 'session key'.
If any one knows, please explain about 'session key' .........
thanks,

Public key and private key are used in assymetric encryption algorithms.
In symmetric encryption algorithms, both parties used the same key for encryption and decryption, which is exchanged at start of the session. I think this common key is what they are referring to as 'session key'
