Overview
The concept of cryptography dates back to ancient civilizations. Symmetric-key cryptography uses the same key for both encryption and decryption. Asymmetric-key cryptography uses a pair of keys: one for encryption and another for decryption. Hash functions are used to verify the integrity of data. Encryption involves converting plaintext into ciphertext using a cryptographic algorithm and key. Decryption involves converting ciphertext back into plaintext. Cryptography is used in digital signatures to verify the authenticity of electronic documents. Cryptography is also used in cloud computing to ensure the security and integrity of data stored in the cloud. Homomorphic encryption allows computations to be performed on encrypted data.
