pythoncrypt模块安装_python 中 crypto 的aes加密怎么使用

❶ cryptography python怎么安装

windows 版本：
http://www.voidspace.org.uk/python/moles.shtml#pycrypto
软件名：pycrypto-2.0.1.win32-py2.×
2.6版为exe文件，2.5版解压到 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版本安装需要 python setup.py build 和 python setup.py install

❷ 如何在virtualenv虚拟环境中安装mysql-python

接触过virtualenv后，想在这个虚拟环境中安装独立的开发环境。在安装MySQLdb时遇到错误
pc 09:09:30
File "/home/pc/work/VENV/py3/local/lib/python2.7/site-packages/setuptools/sandbox.py", line 50, in run_setup

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

在国内的网上找了好长时间也没有找到办法，大多数是讲如何安装mysql-python的。先说一下解决过程吧
我是在ubuntu14上安装有virtualenv,在全局环境中安装了mysql-server,安装命令
sudo apt-get install mysql-server

后续过程都是在虚拟环境中进行的。我的是py3
开始找到要想使用mysql需要安装libmysqlclient-dev
安装过后在安装mysql-python还是出错

Storing debug log for failure in /home/pc/.pip/pip.log
看到如果没有安装python-dev，需要安装这个就开始安装
sudo apt-get install python-dev
此时在安装mysql-python就可以了，所以安装步骤是
1 安装python-dev
sudo apt-get install python-dev

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

3 安装mysql-python
pip install mysql-python

最后进行验证
(py3)pc@pc-virtual-machine:~/work/VENV/py3/bin$ python
Python 2.7.6 (default, Jun 22 2015, 18:00:18)

>>> import MySQLdb

如果导入没有问题就说明导入成功了。

❸ perl怎么安装Crypt：SSLeay模块

由于要使用到https登录，所以要安装Crypt::SSLeay,

一、linux下安装

在Ubuntu的源里有libcrypt-ssleay-perl模块的，直接

$sudo apt-get install libcrypt-ssleay-perl

就OK，开始不知道，还要下载来自己安装，浪费时间，在此感谢CU上的dajun。

二、在win下安装

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 计算机丢失CRYPT32.dll，怎么重新安装

楼主你好，你可以重新下载一个crypt32dll.dll文件，然后按如下步骤操作：
一、解压后直接拷贝该文件到系统目录里：
1、Windows 95/98/Me系统，复制到C:WindowsSystem目录下。
2、Windows NT/2000系统，复制到C:WINNTSystem32目录下。
3、Windows XP/WIN7/Vista系统，复制到C:WindowsSystem32目录下。
4、如果您的系统是64位的请将文件复制到C:WindowsSysWOW64目录
二、打开"开始-运行-输入regsvr32 crypt32dll.dll"，回车即可解决。
已上传并提供下载连接，可根据需要下载。

❺ 如何为mac python安装pycrypto

解决方案一：安装Vs2008（实测）
完全的无脑流，安装完问题直接解决。
解决方案二：安装Vs2010（未测试）
上次在电脑上装个Vs2010并不能像 vs2008那样直接解决问题，从网上找到如下解决方案，不知是否可行。
打开“<python安装目录>\Lib\distutils\msvc9compiler.py”
找到 toolskey = “VS%0.f0COMNTOOLS” % version，直接修改为 toolskey = ”VS100COMNTOOLS”
解决方案三：安装MinGW（实测）
1、下载安装MinGW，下载地址为：http://sourceforge.net/projects/mingw/files/latest/download?source=files
2、在MinGW的安装目录下找到bin文件夹，找到mingw32-make.exe，复制一份更名为make.exe
3、把MinGW的路径添加到环境变量path中，比如我把MinGW安装到D:\MinGW\中，就把D:\MinGW\bin添加到path中；
4、在<python安装目录>\distutils增加文件distutils.cfg，在文件里输入
[build]
compiler=mingw32
保存；
5、执行原先的模块安装，发现还是报错，报错内容为：error: command ’gcc’ failed: No such file or directory 解决方案是将D:\MinGW\lib再添加到PATH中。
6、如果安装过程中出现 error: Could not find ‘openssl.exe’ 则直接到http://pypi.python.org/pypi/pyOpenSSL/0.13 下载安装即可。
再次执行时安装模块时，发现如下错误：
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 以后不再接受-mno-cygwin为了解决这个问题需要修改<python安装目录>\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))
修改为：
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))
讲了三个解决方案，安装visualstudio太庞大的，没有试，于是就尝试第三种方法。其中openssl.exe的错误没有碰到，应该是已经有了，而distutils.cfg文件的目录在python2.7下面有点不一样，在Python27\Lib\distutils下面。一直到最后个修改项，最终错误是：
error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘PyInt_AsUnsignedLongLongMask’
没有解决。
中间有个警告，在cygwin中使用dos style的path，设置path CYGWIN=nodosfilewarning 来规避
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
这个命令尝试也不行。
在这个url：http://stackoverflow.com/questions/1687283/why-cant-i-just-install-the-pycrypto，国际友人介绍用PyPM来安装，由于要另外安装工具，没有尝试：
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/
后来在这里http://lili-xiang.iteye.com/blog/1796640，看到有预编译好的版本用来安装，在地址http://www.voidspace.org.uk/downloads/pycrypto26/pycrypto-2.6.win-amd64-py3.2.exe下载PyCrypto 2.6 for Python 3.2 64bit，随后安装成功，可以在Komodo IDE 7中使用了。测试代码是这里的：http://ddkangfu.blog.51cto.com/311989/484801
但是例子的代码是跑不起来的，因为aes加密中，cbc模式下是还有个iv参数的，修改成这样
#!/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
才可以正常运行，如果使用ECB模式，就不用最后一个iv参数的。这里使用加密源data作为iv参数是没有意思的，正式使用的时候肯定会另外定义的字符串，记得iv长度要是16位的倍数。代码里还要注意obj2，不能重复使用第一个obj，在加密过程中obj已经改变了，如果不充生成obj2，是无法解密成功的。

❻ “青锋爱分享”Springboot+Python之RSA加解密方案(RSA深入)二

本篇文章要结合上一节文章一起看。

青锋爱分享-RSA-Springboot+Python整合

码云搜索：青锋会有惊喜哦哦。

通过python生成的公钥私钥格式PKCS1 。

生成pem格式如下：

私钥头（-----BEGIN RSA PRIVATE KEY-----）

私钥尾（-----END RSA PRIVATE KEY-----）

我需要将此私钥转换为DER编码的PKCS8未加密格式，以便与java服务器代码一起使用，特别是PKCS8EncodedKeySpec。我已经试过使用rsa和pkcs8命令的OpenSSL，如果有更简单的办法，没有特别需要使用openssl。

RSA私钥格式PKCS1和PKCS8相互转换

RSA公钥格式PKCS1和PKCS8相互转换

以下转换基于openssl命令的操作；

执行：openssl genrsa -out private.pem 1024

iOS上用的是pkcs8格式的公钥
openssl用的是pkcs1格式的公钥
知道私钥以后是可以导出公钥的，所以私钥一定要保证安全
知道公钥不可以导出私钥

解决方案针对是window电脑。

配置：SystemRoot/ System32 环境变量。

1、邮件我的电脑-选择下【属性】。

2、选择高级系统设置

3、选择【高级】-【环境变量】

4、双击打开path，进行编辑

5、接着我们在这名字后面加【；System32】就可以了。

❼ python 中 crypto 的aes加密怎么使用

在刚开始知道这个模块的时候，连基本的Crypto模块的安装都花了很多很多时间来搞，也不知道什么情况反正是折腾很久了才安装起的，记得是包安装起来了，但使用的时候始终提示找不到Crypto.Cipher模块。然后怎么解决的呢？
一、把我的python换成了64位的，本来电脑就是64位的也不知道之前是啥情况安装成32位的了。（O(∩_∩)O哈哈~）
二、安装了VCForPython27.msi
三、在cmd中执行：
pip install pycrypto -i http://mirrors.aliyun.com/pypi/simple/1

经过上边儿的几个步骤，我是能够成功执行
from Crypto.Cipher import AES1

现在上一个实例代码：
# !/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中执行结果：

❽ python mysqldb 安装问题

mysqldb只有python2.5版的，2.6的需要额外的东东，我也记不清了，不过有人把2.6对应的东东弄成一个exe了，直接运行就装上了，也不需要额外配置啥的，你留个邮箱啥的，我给你传过去吧。

import MySQldb?
还是MySQLdb?
l要大写L.
另外:_mysql.pyd是在python安装目录\Lib\site-packages下的

❾ 怎么解决.dll没有被指定在windows上运行

解决.dll没有被指定在windows上运行的方法如下：

1、网络搜索.dll前面的名称，并点击任意下载链接进入下载页面。
