PHP RSA encryption, decryption, signature, verification Because the docking of third-party organizations using the Java version of the RSA encryption and decryption method, all just started on the internet to find a lot of PHP version of the RSA encryption, but most of the docking Java does not apply. The following PHP version is suitable for docking Java interf

In the development of PHP system, the member is often an essential module, and password processing has to face the problem, PHP Mcrypt Encryption Library needs additional settings, many people are directly using MD5 () function encryption, this method is indeed safe, but because MD5 is irreversible encryption, Unable to restore the password, so there are some inc

This key is characterized by the only use of this account in this system can be modified, even if you use this account to set up encryption after deleting the account and re-build an account with the same name is still unable to modify. And this key cannot be cracked. So once encrypted, reload the system or replace the account can not be modified. The only way to

The basic public key cryptography steps were presented by Whitfield Diffie and Martin Hellman in 1976. Mathematical concept: A "prime number" is a positive integer that can only be divisible by 1 and itself (except for the remainder of 0). The first 8 prime numbers are 1, 2, 3, 5, 7, 11, 13, 17 Any positive integer that is not a prime number can be converted to a product of more than two prime numbers and is the only combination. 4=2*2 6=2*3 8=

RSA public Key cryptography was developed in 1977 by Ron Rivest, Adi Shamirh and Lenadleman (Massachusetts Institute of America).The algorithm's name is also their three person initials, the RSA algorithm is based on a very simple number theory fact:Multiplying the two large primes is easy, but it is extremely difficult to factorization the product, so the product can be exposed as the encryption key.Packag

First approach: Using Apt-get (tested with Python2 version) sudo apt-get install python-m2crypto, the M2crypto will be installed in the System Python library. Second way: Install from source ((compatible with python2,3)) sudo apt-get install build-essential python3-dev python-dev libssl-dev swig pip install https://gitlab.com/m2crypto/m2crypto/repository/python3/archive.tar.gz Third Way: Pip installation (incompatible Python3) pip install M2Crypto Th
