Https Encryption Principle
There are basically two types of encryption algorithms
- Symmetric encryption
Encryption with the secret key and decryption with the secret key is the same, more representative is THE AES encryption algorithm
- Asymmetric encryption
The secret key used for encryption is called a public key, and the secret key used for decryption is called a private key. The RSA encryption algorithm commonly used is asymmetric encryption. Hash encryption algorithm Hash algorithm: MD5, SHA1, SHA256 Compared with symmetric encryption, asymmetric encryption has higher security, but takes longer time to encrypt and decrypt data
