Article Introduction：How to use PHP and GMP to perform RSA encryption and decryption algorithm for large integers. The RSA encryption algorithm is an asymmetric encryption algorithm that is widely used in the field of data security. It implements the process of public key encryption and private key decryption based on two particularly large prime numbers and some simple mathematical operations. In the PHP language, the calculation of large integers can be realized through the GMP (GNUMultiplePrecision) library, and the encryption and decryption functions can be realized by combining the RSA algorithm. This article will introduce how to use PHP and GMP libraries to
