Encryption is essential for protecting sensitive information from unauthorized access and maintaining confidentiality. It transforms plain text into ciphertext, which can only be read by someone with the correct decryption key.

• Symmetric encryption uses the same key for both encryption and decryption, making it faster and more efficient for large volumes of data. It is ideal for situations where data is being transmitted within a secure, closed system or where performance and speed are critical, such as encrypting data at rest or databases. However, symmetric encryption requires secure key exchange, which can be a challenge over insecure channels.

• Asymmetric encryption uses a public key for encryption and a private key for decryption. This type of encryption is generally used in situations where secure key exchange over an insecure medium is necessary, such as in digital signatures and establishing secure communication channels over the internet (e.g., SSL/TLS for secure web connections). It is more computationally intensive and slower compared to symmetric encryption, making it less suitable for encrypting large volumes of data.

Here is a simple representation in a table format:

Encryption Type	Use Case	Key Exchange	Speed
Symmetric	Encrypting large volumes of data, such as databases and data at rest.	Must be kept secure	Fast
Asymmetric	Secure key exchange over an insecure medium, digital signatures, and establishing secure connections.	Public key is openly shared	Slow but secure
