Commonly used encryption methods on websites include the following 4 types: 1. SSL/TLS, by establishing a secure encrypted connection for communication between the client and the server, ensuring that the transmitted data is encrypted on the network, and Prevent malicious acquisition by unauthorized persons; 2. HTTPS, which adds an extension of the SSL/TLS encryption protocol to the HTTP protocol; 3. AES, a symmetric encryption algorithm, is widely used in the encryption and decryption process of data; 4. RSA, an asymmetric encryption algorithm used for data encryption, decryption and digital signature.

Commonly used encryption methods on websites include the following:

  1. SSL/TLS:

    SSL (Secure Sockets Layer) and its successor TLS ( Transport Layer Security) is the most common encryption protocol. They work by establishing a secure, encrypted connection for communication between client and server, ensuring that transmitted data is encrypted on the network and protected from malicious acquisition by unauthorized persons. The working principle is to achieve encryption and authentication of communication data by using a combination of symmetric encryption and asymmetric encryption.

  2. HTTPS:

    HTTPS (Hypertext Transfer Protocol Secure) is an extension that adds the SSL/TLS encryption protocol to the HTTP protocol and is used to protect web browsers and servers. communication between. By using the SSL/TLS encryption protocol, HTTPS ensures that transmitted data is secure during transmission, preventing eavesdropping and tampering.

  3. AES (Advanced Encryption Standard):

    AES is a symmetric encryption algorithm that is widely used in the encryption and decryption process of data. AES uses the same key to encrypt and decrypt data, and its security relies on the confidentiality of the key. The AES algorithm uses block encryption to divide plain text data into fixed-length data blocks, and then encrypts each data block.

  4. RSA:

    RSA is an asymmetric encryption algorithm used for data encryption, decryption and digital signature. It is based on the property that the product of two large prime numbers is difficult to decompose, one of which is used to generate the public key and the other to generate the private key. The RSA encryption process uses the public key to encrypt data and then uses the private key to decrypt it.

How these encryption methods work mainly involves using different encryption algorithms and keys to encrypt and decrypt data. Symmetric encryption uses the same key for encryption and decryption, while asymmetric encryption uses a public and private key for encryption and decryption. Secure encryption requires ensuring the security of keys and the correct implementation of encryption algorithms.
