Encryption Techniques

Encryption techniques are methods used to convert data into a coded format to prevent unauthorized access. These techniques play a crucial role in ensuring the security and privacy of sensitive information across digital platforms.

  1. Symmetric Encryption: A method where the same key is used for both encryption and decryption. Examples include AES (Advanced Encryption Standard) and DES (Data Encryption Standard).
  2. Asymmetric Encryption: Also known as public-key encryption, this technique uses a pair of keys - a public key for encryption and a private key for decryption. RSA and ECC (Elliptic Curve Cryptography) are common asymmetric encryption algorithms.
  3. Hashing: While not encryption, hashing is a cryptographic technique used to transform data into a fixed-size value known as a hash. Used for verifying data integrity, popular hashing algorithms include MD5 and SHA-256.
  4. End-to-End Encryption: A method that ensures data is encrypted from the senders device to the recipients device, making it inaccessible to intermediaries. Applications like Signal and WhatsApp employ end-to-end encryption for secure communication.

Understanding various encryption techniques is essential for safeguarding sensitive information in an interconnected digital world.
