- Glossary: ChaCha20ChaCha20 is a modern, high-speed, and highly secure symmetric-key stream cipher developed by cryptographer Daniel J. Bernstein in 2008. It is widely used for encrypting data in applications where both performance and security are critical, such as VPNs, messaging apps, and secure internet protocols.
- Glossary: Triple DESTriple DES (also known as 3DES or TDES), officially called the Triple Data Encryption Algorithm (TDEA), is a symmetric-key block cipher that applies the Data Encryption Standard (DES) algorithm three times to each data block. It was developed to address the vulnerabilities of single DES, which became susceptible to brute-force attacks as computational power increased.
