Should session data be encrypted?
If your application is on a shared host, and your session data is being kept in some unsecure central location where it could be open for other users to read, then yes, technically there is some security benefit to encrypting your sessions.
How is cryptography used to encrypt data?
Encryption is the method by which information is converted into secret code that hides the information’s true meaning. The science of encrypting and decrypting information is called cryptography. In computing, unencrypted data is also known as plaintext, and encrypted data is called ciphertext.

What can be done if session data is unencrypted?
What damage can be done if session data is unencrypted and a hacker saw the data in plain sight (i.e., the md5 hash of the fingerprint and the logged_in = true ). Can he actually log himself in or he must first “crack” the md5? Note: md5 was used to simplify example, a much better hashing algo is used in real life.
What happens if a session key is on a hard disk?
In the second scenario, the same issue applies: if the key is on the hard disk along with the session data, an attacker can simply read the keys and decrypt the session data.
Where is session data stored in Windows 10?
Session data may be stored on the filesystem / in a database – and hence persist in backups.
