]) Parameters Describe String Necessary. Specifies the string to be computed. Raw Optional. Specify hexadecimal or binary output format: TRUE-original 20 character binary format false-default. 40-character hexadecimal number The function returns a 40-bit hexadecimal number, and if the parameter raw_output is true, then a 20-bit binary number is returned, and the default is Raw_output is false. Here we want to highlight the following: Sha a

This article mainly introduces the Python encryption module md5, sha, and crypt instances. This article provides the MD5 and crypt module code examples, for more information, see the MD5 (Message-Digest Algorithm 5) module to calculate information ciphertext (Information Digest) and obtain a 128-bit ciphertext. The sha module is similar to md5, but generates a 160-bit signature. The usage is the same. The following

content usually contains special characters, need to encode conversion, in the network through the URL transmission to pay attention to base64 encoding is URL security Echo ' private key encrypted: '. $encrypted. ' \ n "; echo "echo "Public key decrypt:\n"; echo "Openssl_public_decrypt (Base64_decode ($encrypted), $decrypted, $pu _key);//private key encrypted content can be decrypted by public key After the echo ' public key is decrypted: '. $decrypted.

Creates a class that changes the value of each character of a string by using the "^" XOR operator in the bitwise operation to vary the string to a specified value, so that an encrypted string can be obtained. When the encrypted string as a program input, and then with the specified value of the different or operation, to restore the encrypted string to the original string value. Copy Code code as follows: Import Java.util.Scanner; public class

This article mainly introduces the RSA encryption/decryption and signature/verification functions implemented under Python, and analyzes the implementation method of RSA encryption and decryption in Python, and the use of signature and verification function, which can be referenced by a friend. This article describes the RSA encryption/decryption and signature/v

This article mainly introduces the php symmetric encryption algorithm example. if you need a friend, refer to the php symmetric encryption algorithm. KEY is a previously defined constant. The code is as follows: Mcrypt: encrypt ();Mcrypt: decrypt (); The code is as follows: Defined ('root') or exit ('Access Denied '); Class Mcrypt {Public static function enc
