Security is not additive, but subtractive—TLS 1.3 achieves this through a “minimalist” cipher suite, removing over 10 features (such as compression and renegotiation), and reducing the cipher suites from 37 to 5,AES-CBC was directly removed due to security risks. Meanwhile, the ChaCha20-Poly1305 algorithm has become the new favorite in the TLS protocol, gradually taking center … Read more
1. What is it Symmetric encryption refers to the use of the same key for both encryption and decryption. The process of encryption and decryption is illustrated in the following diagram: Symmetric encryption algorithms have the advantages of fast speed and high efficiency, but they face challenges in key distribution and are susceptible to eavesdropping. … Read more
# Technology # Sharing Author / Cabinet Sweeping Monk In encryption algorithms, we often encounter a new type of algorithm called ChaCha20. Now let’s take a look at its features and application scenarios. Salsa20 is a stream cipher algorithm submitted to eSTREAM by Daniel J. Bernstein. It is built on a pseudo-random function based on … Read more
