pythoncrypt模塊安裝_python 中 crypto 的aes加密怎麼使用

❶ cryptography python怎麼安裝

windows 版本：
http://www.voidspace.org.uk/python/moles.shtml#pycrypto
軟體名：pycrypto-2.0.1.win32-py2.×
2.6版為exe文件，2.5版解壓到 your2.5path/Lib/site-packages

linux 版本：
http://www.amk.ca/python/code/crypto.html
Manual：http://www.amk.ca/python/writing/pycrypt/
Linux版本安裝需要 python setup.py build 和 python setup.py install

❷ 如何在virtualenv虛擬環境中安裝mysql-python

接觸過virtualenv後，想在這個虛擬環境中安裝獨立的開發環境。在安裝MySQLdb時遇到錯誤
pc 09:09:30
File "/home/pc/work/VENV/py3/local/lib/python2.7/site-packages/setuptools/sandbox.py", line 50, in run_setup
lambda: execfile(

File "/tmp/easy_install-FtC77Z/MySQL-python-1.2.5/setup_posix.py", line 25, in mysql_config
EnvironmentError: mysql_config not found

在國內的網上找了好長時間也沒有找到辦法，大多數是講如何安裝mysql-python的。先說一下解決過程吧
我是在ubuntu14上安裝有virtualenv,在全局環境中安裝了mysql-server,安裝命令
sudo apt-get install mysql-server

後續過程都是在虛擬環境中進行的。我的是py3
開始找到要想使用mysql需要安裝libmysqlclient-dev
安裝過後在安裝mysql-python還是出錯

Storing debug log for failure in /home/pc/.pip/pip.log
看到如果沒有安裝python-dev，需要安裝這個就開始安裝
sudo apt-get install python-dev
此時在安裝mysql-python就可以了，所以安裝步驟是
1 安裝python-dev
sudo apt-get install python-dev

2 安裝 libmysqlclient-dev
sudo apt-get install libmysqlclient-dev

3 安裝mysql-python
pip install mysql-python

最後進行驗證
(py3)pc@pc-virtual-machine:~/work/VENV/py3/bin$ python
Python 2.7.6 (default, Jun 22 2015, 18:00:18)

Type "help", "right", "credits" or "license" for more information.
>>> import MySQLdb
>>>
如果導入沒有問題就說明導入成功了。

❸ perl怎麼安裝Crypt：SSLeay模塊

由於要使用到https登錄，所以要安裝Crypt::SSLeay,

一、linux下安裝

在Ubuntu的源里有libcrypt-ssleay-perl模塊的，直接

$sudo apt-get install libcrypt-ssleay-perl

就OK，開始不知道，還要下載來自己安裝，浪費時間，在此感謝CU上的dajun。

二、在win下安裝

No installed SSL libraries found in any of the following places.

/local

/local/ssl

/opt/ssl

/usr

/usr/local

/usr/local/ssl

/usr/local/openssl

You will have to either specify a directory location at the following

prompt, or rerun the Makefile.PL program and use the --lib switch

to specify the path. If the path in question is considered standard

on your platform, please consider filing a bug report in order to

have it taken into account in a subsequent version of Crypt::SSLeay.

This host looks like it is running Debian. Crypt::SSLeay needs to

be compiled with C headers that the libssl-dev package makes

available. Please install that package before trying to build this

mole. (You can always deinstall the package afterwards, once

Crypt::SSLeay has been built).

Which SSL install path do you want to use? /usr/local/ssl

/usr/local/ssl does not appear to be an SSL library installation, since

the required header files were not found. The build cannot proceed.

❹ 計算機丟失CRYPT32.dll，怎麼重新安裝

樓主你好，你可以重新下載一個crypt32dll.dll文件，然後按如下步驟操作：
一、解壓後直接拷貝該文件到系統目錄里：
1、Windows 95/98/Me系統，復制到C:WindowsSystem目錄下。
2、Windows NT/2000系統，復制到C:WINNTSystem32目錄下。
3、Windows XP/WIN7/Vista系統，復制到C:WindowsSystem32目錄下。
4、如果您的系統是64位的請將文件復制到C:WindowsSysWOW64目錄
二、打開"開始-運行-輸入regsvr32 crypt32dll.dll"，回車即可解決。
已上傳並提供下載連接，可根據需要下載。

❺ 如何為mac python安裝pycrypto

解決方案一：安裝Vs2008（實測）
完全的無腦流，安裝完問題直接解決。
解決方案二：安裝Vs2010（未測試）
上次在電腦上裝個Vs2010並不能像 vs2008那樣直接解決問題，從網上找到如下解決方案，不知是否可行。
打開「<python安裝目錄>\Lib\distutils\msvc9compiler.py」
找到 toolskey = 「VS%0.f0COMNTOOLS」 % version，直接修改為 toolskey = 」VS100COMNTOOLS」
解決方案三：安裝MinGW（實測）
1、下載安裝MinGW，下載地址為：http://sourceforge.net/projects/mingw/files/latest/download?source=files
2、在MinGW的安裝目錄下找到bin文件夾，找到mingw32-make.exe，復制一份更名為make.exe
3、把MinGW的路徑添加到環境變數path中，比如我把MinGW安裝到D:\MinGW\中，就把D:\MinGW\bin添加到path中；
4、在<python安裝目錄>\distutils增加文件distutils.cfg，在文件里輸入
[build]
compiler=mingw32
保存；
5、執行原先的模塊安裝，發現還是報錯，報錯內容為：error: command 』gcc』 failed: No such file or directory 解決方案是將D:\MinGW\lib再添加到PATH中。
6、如果安裝過程中出現 error: Could not find 『openssl.exe』則直接到http://pypi.python.org/pypi/pyOpenSSL/0.13 下載安裝即可。
再次執行時安裝模塊時，發現如下錯誤：
D:\MinGW\bin\gcc.exe -mno-cygwin -mdll -O -Wall 「-ID:\Program Files\Python27\inc
lude」「-ID:\Program Files\Python27\include」「-ID:\Program Files\Python27\PC」 -c
../libdasm.c -o build\temp.win32-2.7\Release\..\libdasm.o
cc1.exe: error:unrecognized command line option 『-mno-cygwin』
error: command 『gcc』 failed with exit status 1
原因是gcc 4.6.x 以後不再接受-mno-cygwin為了解決這個問題需要修改<python安裝目錄>\distutils\cygwinccompiler.py文件。找到：
self.set_executables(compiler='gcc -mno-cygwin -O -Wall',
compiler_so='gcc -mno-cygwin -mdll -O -Wall',
compiler_cxx='g++ -mno-cygwin -O -Wall',
linker_exe='gcc',
linker_so='%s -mno-cygwin %s %s'
% (self.linker_dll, shared_option,
entry_point))
修改為：
self.set_executables(compiler='gcc -O -Wall',
compiler_so='gcc -mdll -O -Wall',
compiler_cxx='g++ -mno-cygwin -O -Wall',
linker_exe='gcc',
linker_so='%s -mno-cygwin %s %s'
% (self.linker_dll, shared_option,
entry_point))
講了三個解決方案，安裝visualstudio太龐大的，沒有試，於是就嘗試第三種方法。其中openssl.exe的錯誤沒有碰到，應該是已經有了，而distutils.cfg文件的目錄在python2.7下面有點不一樣，在Python27\Lib\distutils下面。一直到最後個修改項，最終錯誤是：
error: expected 『=』, 『,』, 『;』, 『asm』 or 『__attribute__』 before 『PyInt_AsUnsignedLongLongMask』
沒有解決。
中間有個警告，在cygwin中使用dos style的path，設置path CYGWIN=nodosfilewarning 來規避
cygwin warning:
MS-DOS style path detected: C:\cygwin\home\ADMINI~1\hadoop\/build/native
Preferred POSIX equivalent is: /home/ADMINI~1/hadoop/build/native
CYGWIN environment variable option "nodosfilewarning" turns off this warning.
Consult the user's guide for more details about POSIX paths:
http://cygwin.com/cygwin-ug-net/using.html#using-pathnames
12/02/13 10:34:53 INFO namenode.NameNode: STARTUP_MSG:
python setup.py install build --compiler=mingw32
這個命令嘗試也不行。
在這個url：http://stackoverflow.com/questions/1687283/why-cant-i-just-install-the-pycrypto，國際友人介紹用PyPM來安裝，由於要另外安裝工具，沒有嘗試：
You may use PyPM to install (pre-built binary package of) pycrypto:
C:> pypm install pycrypto
Ready to perform these actions:
The following packages will be installed:
pycrypto-2.0.1
Get: [pypm.activestate.com] pycrypto 2.0.1-1
Installing pycrypto-2.0.1
PyPM can be installed by installing ActivePython.http://www.activestate.com/activepython/
後來在這里http://lili-xiang.iteye.com/blog/1796640，看到有預編譯好的版本用來安裝，在地址http://www.voidspace.org.uk/downloads/pycrypto26/pycrypto-2.6.win-amd64-py3.2.exe下載PyCrypto 2.6 for Python 3.2 64bit，隨後安裝成功，可以在Komodo IDE 7中使用了。測試代碼是這里的：http://ddkangfu.blog.51cto.com/311989/484801
但是例子的代碼是跑不起來的，因為aes加密中，cbc模式下是還有個iv參數的，修改成這樣
#!/usr/bin/env python
# -*- coding: utf-8 -*-
from Crypto.Cipher import AES
PADDING = '\0'
pad_it = lambda s: s+(16 - len(s)%16)*PADDING
if __name__ == "__main__":
key = '1234567890123456'
data = 'qwertyuiopasdfgh'
obj = AES.new(key, AES.MODE_CBC, data)
#obj = AES.new(key, AES.MODE_ECB)
crypt = obj.encrypt(data)
print crypt
#obj2 = AES.new(key, AES.MODE_ECB)
obj2 = AES.new(key, AES.MODE_CBC, data)
recovery = obj2.decrypt(crypt)
print recovery
才可以正常運行，如果使用ECB模式，就不用最後一個iv參數的。這里使用加密源data作為iv參數是沒有意思的，正式使用的時候肯定會另外定義的字元串，記得iv長度要是16位的倍數。代碼里還要注意obj2，不能重復使用第一個obj，在加密過程中obj已經改變了，如果不充生成obj2，是無法解密成功的。

❻ 「青鋒愛分享」Springboot+Python之RSA加解密方案(RSA深入)二

本篇文章要結合上一節文章一起看。

青鋒愛分享-RSA-Springboot+Python整合

碼雲搜索：青鋒會有驚喜哦哦。

通過python生成的公鑰私鑰格式PKCS1 。

生成pem格式如下：

私鑰頭（-----BEGIN RSA PRIVATE KEY-----）

私鑰尾（-----END RSA PRIVATE KEY-----）

我需要將此私鑰轉換為DER編碼的PKCS8未加密格式，以便與java伺服器代碼一起使用，特別是PKCS8EncodedKeySpec。我已經試過使用rsa和pkcs8命令的OpenSSL，如果有更簡單的辦法，沒有特別需要使用openssl。

RSA私鑰格式PKCS1和PKCS8相互轉換

RSA公鑰格式PKCS1和PKCS8相互轉換

以下轉換基於openssl命令的操作；

-----BEGIN PUBLIC KEY-----

/7/FnMag1IelSfdronPBDxazp6

NUmQZITsYK6CsEl/ewIDAQAB

-----END PUBLIC KEY-----

可以看到和上面4，5的結果是一致的；

最後一點：
iOS上用的是pkcs8格式的公鑰
openssl用的是pkcs1格式的公鑰
知道私鑰以後是可以導出公鑰的，所以私鑰一定要保證安全
知道公鑰不可以導出私鑰

解決方案針對是window電腦。

配置：SystemRoot/ System32 環境變數。

1、郵件我的電腦-選擇下【屬性】。

2、選擇高級系統設置

3、選擇【高級】-【環境變數】

4、雙擊打開path，進行編輯

5、接著我們在這名字後面加【；System32】就可以了。

❼ python 中 crypto 的aes加密怎麼使用

在剛開始知道這個模塊的時候，連基本的Crypto模塊的安裝都花了很多很多時間來搞，也不知道什麼情況反正是折騰很久了才安裝起的，記得是包安裝起來了，但使用的時候始終提示找不到Crypto.Cipher模塊。然後怎麼解決的呢？
一、把我的python換成了64位的，本來電腦就是64位的也不知道之前是啥情況安裝成32位的了。（O(∩_∩)O哈哈~）
二、安裝了VCForPython27.msi
三、在cmd中執行：
pip install pycrypto -i http://mirrors.aliyun.com/pypi/simple/1

經過上邊兒的幾個步驟，我是能夠成功執行
from Crypto.Cipher import AES1

現在上一個實例代碼：
# !/usr/bin/env python
# coding: utf-8
'''

'''

from Crypto.Cipher import AES
from binascii import b2a_hex, a2b_hex

class MyCrypt():
def __init__(self, key):
self.key = key
self.mode = AES.MODE_CBC

def myencrypt(self, text):
length = 16
count = len(text)
print count
if count < length:
add = length - count
text= text + ('\0' * add)

elif count > length:
add = (length -(count % length))
text= text + ('\0' * add)

# print len(text)
cryptor = AES.new(self.key, self.mode, b'0000000000000000')
self.ciphertext = cryptor.encrypt(text)
return b2a_hex(self.ciphertext)

def mydecrypt(self, text):
cryptor = AES.new(self.key, self.mode, b'0000000000000000')
plain_text = cryptor.decrypt(a2b_hex(text))
return plain_text.rstrip('\0')

if __name__ == '__main__':
mycrypt = MyCrypt('abcdefghjklmnopq')
e = mycrypt.myencrypt('hello,world!')
d = mycrypt.mydecrypt(e)
print e
print d
0414243

在cmd中執行結果：

❽ python mysqldb 安裝問題

mysqldb只有python2.5版的，2.6的需要額外的東東，我也記不清了，不過有人把2.6對應的東東弄成一個exe了，直接運行就裝上了，也不需要額外配置啥的，你留個郵箱啥的，我給你傳過去吧。

import MySQldb?
還是MySQLdb?
l要大寫L.
另外:_mysql.pyd是在python安裝目錄\Lib\site-packages下的

❾ 怎麼解決.dll沒有被指定在windows上運行

解決.dll沒有被指定在windows上運行的方法如下：

1、網路搜索.dll前面的名稱，並點擊任意下載鏈接進入下載頁面。
