Cryptography vs Encryption

What is cryptography?
Cryptography is the science of securing information and communications using mathematical techniques to protect data from unauthorized access or tampering. It includes Encryption, Hashing, Digital signature and Authentication.

What is encryption?
Encryption is a technique in cryptography used to converts plain text into ciphertext. It typically uses a key to encrypt data or information. There are two types of encryptions which are Symmetric(uses the same key for encryption and decryption) and asymmetric(uses a public key and a private key).
