Encryption technology is the backbone of modern cybersecurity. It ensures that data transmitted over networks remains secure and private. Below are some common encryption techniques used today:
Symmetric Encryption: This method uses a single key for both encryption and decryption. The same key is shared between the sender and the receiver. An example of symmetric encryption is AES (Advanced Encryption Standard).
Asymmetric Encryption: Unlike symmetric encryption, asymmetric encryption uses two different keys: a public key and a private key. The public key is used for encryption, while the private key is used for decryption. RSA is a well-known example of asymmetric encryption.
Hashing: Hashing is a one-way function that converts data into a fixed-size string of characters. It is commonly used for password storage. A popular hashing algorithm is SHA-256.
Public Key Infrastructure (PKI): PKI is a framework that uses public key cryptography to establish trust in digital transactions. It includes components such as digital certificates, certificate authorities, and certificate revocation lists.
VPN (Virtual Private Network): A VPN creates a secure and encrypted connection between your device and a remote server. It is commonly used to protect data transmitted over public Wi-Fi networks.
