What is Cryptography

Cryptography is used to secure and protect data during communication.
It is helpful to prevent unauthorized person or group of users from accessing any confidential data.
Encryption and Decryption are the two essential functionalities of cryptography.

Encryption is a process of converting normal data into an unreadable form whereas Decryption is a method of converting the unreadable/coded data into its original form.
Encryption is done by the person who is sending the data to the destination, but the decryption is done at the person who is receiving the data.
The same algorithm with the same key is used for both the encryption-decryption processes.

Symmetric-key encryption are algorithms which use the same cryptographic keys for both encryption of plaintext and decryption of ciphertext.
Asymmetric encryption uses 2 pairs of key for encryption. Public key is available to anyone while the secret key is only made available to the receiver of the message. This boots security.
Public key cryptography is an encryption system which is based on two pairs of keys. Public keys are used to encrypt messages for a receiver.
Private key may be part of a public/ private asymmetric key pair. It can be used in asymmetric encryption as you can use the same key to encrypt and decrypt data
Pre-shared key (PSK) is a shared secret which was earlier shared between the two parties using a secure channel before it is used.

Access tokens are the thing that applications use to make API requests on behalf of a user.
The access token represents the authorization of a specific application to access specific parts of a user’s data.
Access tokens must be kept confidential in transit and in storage.

For security purposes, access tokens may be valid for a short amount of time.
Once they expire, client applications can use a refresh token to "refresh" the access token.
A refresh token is a credential artifact that lets a client application get new access tokens without having to ask the user to log in again
