PHP OpenSSL base64 decryption

First, a recent project access to the fourth party payment, fourth party payment provided by the document requires both sides of OpenSSL with the private key, the public key for RSA encryption to communicate with each other

Ii. Environmental Notes

1, lamp, LNMP can, my environment is lamp for the time being

2, PHP First install the OpenSSL extension, otherwise use the function will be error, specific OpenSSL extension can go to Baidu or reference blog document

Third, the code implementation

1. Send encrypted data

650) this.width=650; "Src=" https://s1.51cto.com/wyfs02/M00/07/4B/wKiom1nHIzmypONkAABnpYPfLKs296.png-wh_500x0-wm_ 3-wmp_4-s_3212391313.png "title=" 1.png "alt=" Wkiom1nhizmyponkaabnpypflks296.png-wh_50 "/>

<?php

Encryption

Composing encrypted data

$arr = Array (

' Name ' + ' Test ',//Membership account for third-party platforms

' Password ' + ' test ',//Membership password for third-party platforms

' Amount ' = ' 100 ',//Transfer amount, minimum 100, integer multiples of 100

' Order_sn ' + ' 123456789abc ', the order number generated by//Trader's Exchange (third party platform needs to be returned after processing)

' Sign ' = ' 86E06157205D5155F5FDDDCF077604FD ', sign generated by//Trader's Exchange (third party platform needs to be returned after processing)

);

First turn to JSON-formatted data

$arr = Json_encode ($arr);

Get an encrypted string based on the private key

$key = "Private key content string";

$res = "-----BEGIN public KEY-----\ n".

WordWrap ($key, +, "\ n", true).

"\ n-----END public KEY-----";

openssl_private_encrypt ($aRR, $data, $res);

Base64 encoding

$data = Base64_encode ($data);

Send a POST request

$to _arr = Array (

' Data ' = $data

);

POST request ignored

2. Get encrypted string decryption

<?php

Decrypt

$data = "Data encryption string returned by fourth party";

$key = "Fourth party provided public key content string";

$res = "-----BEGIN public KEY-----\ n".

WordWrap ($pubKey, +, "\ n", true).

"\ n-----END public KEY-----";

Decrypting a string

$crypto = ";

foreach (Str_split (Base64_decode ($data),) as $chunk) {

Openssl_public_decrypt ($chunk, $decryptData, $res);//$decryptData as decrypted data

$crypto. = $decryptData;

}

Parse JSON data to get an array

$arr = Json_decode ($crypto);

Print results

Var_dump ($arr);
