    Encryption Types

    There are several types of encryption, each with its own strengths and weaknesses. Here are the main types of encryption:

    Symmetric Encryption

    • Uses the same key for both encryption and decryption
    • Faster and more efficient than asymmetric encryption
    • Examples: AES (Advanced Encryption Standard), DES (Data Encryption Standard)

    Asymmetric Encryption

    • Uses a pair of keys: a public key for encryption and a private key for decryption
    • More secure than symmetric encryption, but slower and less efficient
    • Examples: RSA (Rivest-Shamir-Adleman), elliptic curve cryptography

    Hash Functions

    • One-way encryption, cannot be decrypted
    • Used for data integrity and authenticity verification
    • Examples: SHA-256 (Secure Hash Algorithm 256), MD5 (Message-Digest Algorithm 5)

    Block Ciphers

    • Encrypt data in fixed-length blocks
    • Examples: AES, DES

    Stream Ciphers

    • Encrypt data in a continuous stream
    • Examples: RC4 (Rivest Cipher 4), FISH (Fast and Simple Hash)

    Note: These are the main types of encryption, but there are other variations and hybrids, such as hybrid encryption, which combines symmetric and asymmetric encryption.
