What is Cryptography? And How You Can Secure Your Data | UpGuard

Cryptography is the practice of securing and transmitting data and information in a form that only authorized parties can understand. https://www.upguard.com/blog/encryption processes encode the original message using crypto-mathematical concepts, and rule-based calculations called algorithms to protect against https://www.upguard.com/blog/malware or https://www.upguard.com/blog/cyber-attack.

There are two main types of symmetric key cryptography: Stream Cipher - A streaming algorithm encrypts plaintext bit-by-bit, a single bit at a time.

Some of the most important block cipher algorithms include Triple DES (Data Encryption Standard), AES (Advanced Encryption Standard), and Twofish.

Examples of public-key cryptography or asymmetric-key cryptography include Diffie-Hellman key exchange, RSA (Rivest–Shamir–Adleman), DSA (Digital Signature Algorithm), ECC (elliptic curve cryptography), and post-quantum cryptography.
