Symmetric encryption is a type of encryption where the same key is used for both the
encryption and decryption of data.
Example: AES (Advanced Encryption Standard):
Asymmetric encryption, also known as public-key encryption, uses a pair of keys - a
public key for encryption and a private key for decryption.
Example: RSA (Rivest-Shamir-Adleman)
Encoding and decoding are processes used to convert data between different representations.
Examples : base64, base10, and base16 (hexadecimal):
Hashing is a process used in computer science and cryptography to convert data into a
fixed-size string of characters(hexadecimal number). It takes an input message and return a fixed-length string, which appears random but is deterministic.
Examples: sha-256, sha-384, and sha-512
