Encryption is a fundamental concept in cybersecurity, ensuring data confidentiality and integrity. Here are some common types of encryption used to protect information:
Symmetric Encryption
Symmetric encryption uses a single key for both encryption and decryption. This key must be shared securely between the sender and receiver.
- Advantages: Fast and efficient.
- Disadvantages: Requires secure key exchange.
Asymmetric Encryption
Asymmetric encryption uses two keys: a public key for encryption and a private key for decryption.
- Advantages: Provides secure key exchange without the need for a secure channel.
- Disadvantages: Slower than symmetric encryption.
Hashing
Hashing is a one-way encryption process that converts data into a fixed-size string of characters. It is commonly used for password storage and data integrity checks.
- Advantages: Fast and secure.
- Disadvantages: Not reversible.
Hybrid Encryption
Hybrid encryption combines symmetric and asymmetric encryption to leverage the benefits of both.
- Advantages: Combines the speed of symmetric encryption with the security of asymmetric encryption.
- Disadvantages: More complex than other types of encryption.
