问题描述
我必须接收一些使用共享密钥用3DES加密的数据。
我正在使用php7和openssl_decrypt函数,但无法重新创建发送给我的文档示例的结果。
i had to receive some data encrypted with 3DES with shared keys.I'm using php7 and openssl_decrypt function, but I'm not able to recreate the result of the example of the documentation sent to me.
OpenSSL创建发送给我的数据的命令如下:
The OpenSSL command that create the data sent to me is the following:
openssl enc -des-ede3-cbc -base64 -K 17839778773fadde0066e4578710928988398877bb123789 -iv 00000000 -in D:/in.txt
Example:
string_encoded: 123456
data_to_decrypt: Ja79hWTRfBE=
我尝试使用在线工具解码 Ja79hWTRfBE =,并成功获取 123456。
(我使用了此工具:,带有输入文本(十六进制) 25aefd8564d17c11,函数:3DES,模式:CBC,密钥(十六进制)17839778773fadde0066e4578710928988398877bb123789,iv:00000000)
I tried to decode "Ja79hWTRfBE=" with an online tool and I successfully obtain "123456".(I used this tool: http://tripledes.online-domain-tools.com/ with input text (hex) "25aefd8564d17c11", function: 3DES, mode: CBC, key (hex) 17839778773fadde0066e4578710928988398877bb123789, iv: 00000000 )
php代码:
$key = "17839778773fadde0066e4578710928988398877bb123789";
$decData = openssl_decrypt(base64_decode('Ja79hWTRfBE='), 'DES-EDE3-CBC', $key, 0, "00000000");
var_dump($decData);
var_dump给我bool(false)。
var_dump return me bool(false).
我在做什么错了?
推荐答案
我可以使用以下代码重现您的目标:
i can reproduce your goal with the following code:
<?php
$data = "123456";
$method = "DES-EDE3";
$key = "17839778773fadde0066e4578710928988398877bb123789";
$options = 0;
// transform the key from hex to string
$key = pack("H*", $key);
// encrypt
$enc = openssl_encrypt($data, $method, $key, $options);
// decrypt
$dec = openssl_decrypt($enc, $method, $key, $options);
echo "plain: ".$data." encrypted: ".$enc." decrypted: ".$dec;
- 设置没有base64的数据
- 使用DES-EDE3方法
- 将密钥(从十六进制转换为字符串)
