sock.connect( (address, port) ):将套接字连接到定义的主机和端口 sock.recv( bufferLength[, flags] ):从套接字接收数据,最多buflen(要接收的最大字节数)字节 sock.recvfrom( bufferLength[, flags] ):从套接字接收数据,最多buflen字节,并返回数据来自的远程主机和端口 sock.send( data[, flags] ):...
It is the reverse of the encryption process. In this, we convert ciphertext into the plain text. 它与加密过程相反。 在此,我们将密文转换为纯文本。 In the context of storing passwords into SQL tables, we use encryption to convert passwords (plain text) into an encrypted form (ciphertext). ...
The cipher text is decrypted using the password, and the plain text is displayed. If the password turns out incorrect, the system throws an error. Output: 3. RSA Algorithms RSA algorithm implements Asymmetric Key Cryptography. It uses two keys for encryption and decryption of text – a public...

In the step, we will use the symmetric key generated in step 1 along with text(password) that we want to encrypt. We use the cipher_suite.encrypt() function for generating a ciphered text from the string: 1 2 3 4 5 from cryptography.fernet import Fernet key = b'PCHl_MjGyEyBxL...
