encryption features: Fixed-length output: No matter how big the raw data is, the results are of the same size.

Encryption, decryption, and OpenSSL private CA I. Common Algorithms Common encryption algorithms and protocols include symmetric encryption, asymmetric encryption, and one-way encryption. 1. symmetric encryption: one key is used for encryption and decryption. algorithms can be made public and keys cannot be public, because encryption relies on keys. Security depends on keys rather than algorithms; Common algorithms: DES (Data Encryption Standard, 56 b
