使用nodejs crypto 与 php 的 mcrypt 解密blowfish-ecb
我正在尝试使用内置加密库在 Node.js 中解码以下 Base64 编码的密文

它似乎可以使用字符串 typeconfig.sys^_-
作为密钥与 PHP 的 mcrypt 函数一起使用,如将值输入 http://www.tools4noobs.com/online_tools/decrypt/ 并选择 Blowfish、ECB、Base64 解码。
然而,当我在 Node.js 中运行以下代码时:
var crypto = require('crypto');
var data = "2tGiKhSjSQEjoDNukf5BpfvwmdjBtA9kS1EaNPupESqheZ1TCr5ckEdWUvd+e51XWLUzdhBFNOBRrUB5jR64Pjf1VKvQ4dhcDk3Fdu4hyUoBSWfY053Rfd3fqpgZVggoKk4wvmNiCuEMEHxV3rGNKeFzOvP/P3O5gOF7HZYa2dgezizXSgnnD6mCp37OJXqHuAngr0pps/i9819O6FyKgu6t2AzwbWZkP2sXvH3OGRU6oj5DFTgiKGv1GbrM8mIrC7rlRdNgiJ9dyHrOAwqO+SVwzhhTWj1K//PoyyzDKUuqqUQ6AvJl7d1o5sHNzeNgJxhywMT9F10+gnliBxIg8gGSmzBqrgwUNZxltT4uEKz67u9eJi59a0HBBi/2+umzwOCHNA4jl1x0mv0MhYiX/A==";
var decipher = crypto.createDecipher('bf-ecb', 'typeconfig.sys^_-');
data = decipher.update(data, "base64", "utf8");
data += decipher.final("utf8");
console.log(data);
我得到垃圾输出:

我还尝试了对库本身的测试,因为它似乎能够很好地处理它自己编码的内容:
var crypto = require('crypto')
var cipher = crypto.createCipher("bf-ecb", "key");
var data = cipher.update("foobar", "utf8", "base64");
data += cipher.final("base64");
console.log(data);
var decipher = crypto.createDecipher("bf-ecb", "key");
data = decipher.update(data, "base64", "utf8");
data += decipher.final("utf8");
console.log(data);
产生:
y0rq5pYkiU0=
foobar
但复制-并粘贴该 base64 字符串并将其输入到 http://www.tools4noobs.com/online_tools/decrypt/ 与密钥“key”一起也会产生垃圾输出。
这两个库不应该产生相同的输出,还是我做错了什么?
I'm trying to decode the following base64-encoded ciphertext in Node.js with the built-in crypto library

It seems to work with PHP's mcrypt functions using the string typeconfig.sys^_-
as the key, as shown by inputting the value into http://www.tools4noobs.com/online_tools/decrypt/ and selecting Blowfish, ECB, Base64 decode.
However, when I run the following code in Node.js:
var crypto = require('crypto');
var data = "2tGiKhSjSQEjoDNukf5BpfvwmdjBtA9kS1EaNPupESqheZ1TCr5ckEdWUvd+e51XWLUzdhBFNOBRrUB5jR64Pjf1VKvQ4dhcDk3Fdu4hyUoBSWfY053Rfd3fqpgZVggoKk4wvmNiCuEMEHxV3rGNKeFzOvP/P3O5gOF7HZYa2dgezizXSgnnD6mCp37OJXqHuAngr0pps/i9819O6FyKgu6t2AzwbWZkP2sXvH3OGRU6oj5DFTgiKGv1GbrM8mIrC7rlRdNgiJ9dyHrOAwqO+SVwzhhTWj1K//PoyyzDKUuqqUQ6AvJl7d1o5sHNzeNgJxhywMT9F10+gnliBxIg8gGSmzBqrgwUNZxltT4uEKz67u9eJi59a0HBBi/2+umzwOCHNA4jl1x0mv0MhYiX/A==";
var decipher = crypto.createDecipher('bf-ecb', 'typeconfig.sys^_-');
data = decipher.update(data, "base64", "utf8");
data += decipher.final("utf8");
console.log(data);
I get garbage output:

��|@����k"�!�D'u���,x��7����
��9q=q�q��ա>�w�T����H3͜�i)R��zy��C��

I've also tried a test of the library itself, in that it seems to be able to handle stuff it encodes itself fine:
var crypto = require('crypto')
var cipher = crypto.createCipher("bf-ecb", "key");
var data = cipher.update("foobar", "utf8", "base64");
data += cipher.final("base64");
console.log(data);
var decipher = crypto.createDecipher("bf-ecb", "key");
data = decipher.update(data, "base64", "utf8");
data += decipher.final("utf8");
console.log(data);
produces:
y0rq5pYkiU0=
foobar
but copy-and-pasting that base64 string and inputting it into http://www.tools4noobs.com/online_tools/decrypt/ alongside the key "key" produces garbage output also.
Shouldn't these two libraries produce the same output, or is there something I've done wrong?

Node.js 在将密码用作密钥之前计算密码的 MD5 哈希值。据我所知,mcrypt 按原样使用密钥。
计算密码的 MD5 哈希值,并将其用作 mcrypt 密钥。
Node.js computes the MD5 hash of the password before using it as the key. As far as I can tell, mcrypt uses the key as-is.
Compute the MD5 hash of the password, and use that as the mcrypt key.
