PHP:set_error_handler ……need more

Saturday, September 29th, 2007

本来想自己写个 处理的 logger 结果发现通过 set_error_handler 没办法捕获到 fatal & parse 唉,真愁人呐。

.net 上也没有找到办法,后来反到是在 zend.com 上找到了解决 catch fatal 的办法就是在 auto_prepend_file 和 auto_append_file 上做手脚。

prepend 的文件里面有一个 string 里面是个 page 的 包括一个 script 可以把错误信息发送到 的一个 api 上。

而在 append 的文件里通过 ob_get_contents() 来把那个 string 给去掉,如果能去掉就说明程序中间的执行流程正确,无错,如果有 fatal 则没有办法到达 append 文件这步,所以会显示那个 页面。

方法还可以,但是因为每个 都要 prepend & append 可能效率会不行,和 Xuanyan 讨论了一小会暂时还是没有什么好办法来捕获 fatal & parse

XCache & XDebug on road

Friday, September 28th, 2007

终于配置上 XCache 和 XDebug 了,可惜的是 --bridge 一直没搞好,只有双击运行 JavaBridge 后才行,唉,要是能内置到 里就好了。

继续研究 &

如果说之前在 UUSee 是向上研究,既“抽象”、“架构”的话,那么来 IMobile 之后研究方向则是向下,研究底层,研究以前没注意到的更细节的地方了。

Good days, good luck.

redhad下的openssl(安装和卸载)

Friday, September 21st, 2007

转至: http://.csdn.net/baitianhai/archive/2004/10/27/155461.aspx

最近在鼓捣 ,想自己以源代码方式安装软件,不想用rpm方式安装。

首先从httpd开始,先卸载在安装倒是比较容易,不过后来像添加功能,发现编译的时候需要用的安装目录,本人比较愚笨,一顿好找也没有找到,于是就想把也以源代码方式安装。先卸载,此时出现问题,系统好多东西依赖于的库,我查了好多资料也没找到什么办法,于是我最后一狠心,用rpm -e –nodeps给卸载了,然后手动安装了,然后重新启动,这下坏了,好多服务都起不来了,smb,ssh等等,图形模式也起不来了,我欲哭无泪。

因为我是在虚拟机上安装的,smb起不来了,我只能重新安装系统了。这次安装我大多数东西都没选择,一路安装完毕,结果在文本方式发现vi编辑没有颜色了,哎,也不知道是少装了那个东西弄得(各位谁知道麻烦告诉告诉我一下),只能按照猜测重新安装了又添加了一些东西。不过幸运的vi高亮显示功能又有了,遗憾的是具体是那个软件我还是不清楚。有了上次的教训我不敢轻易卸掉系统原来的了,我从网上搜索到了一篇安装的英文文章,地址在 http://www.devside.net//// 我按照上面说的安装了zlib,。步骤简介如下(怕以后忘了)

安装zlib

Home : http://www.gzip.org/zlib/

Package( source) : http://www.gzip.org/zlib/

Our Configuration

Install to : /usr/local

Module types : dynamically and staticly loaded modules, *.so and *.a

Build Instructions

zlib library files are placed into /usr/local/lib and zlib header files are placed into /usr/local/include, by default.

Build static libraries

…/zlib-1.2.1]# ./configure

…/zlib-1.2.1]# make test

…/zlib-1.2.1]# make install

Build shared libraries

…/zlib-1.2.1]# make clean

…/zlib-1.2.1]# ./configure –shared

…/zlib-1.2.1]# make test

…/zlib-1.2.1]# make install

…/zlib-1.2.1]# cp zutil.h /usr/local/include

…/zlib-1.2.1]# cp zutil.c /usr/local/include

/usr/local/lib should now contain…

libz.a

libz.so -> libz.so.1.2.1

libz.so.1 -> libz.so.1.2.1

libz.so.1.2.1

/usr/local/include should now contain…

zconf.h

zlib.h

zutil.h

[Optional] Instructions for non-standard placement of zlib

Create the directory that will contain zlib

…/zlib-1.2.1]# mkdir /usr/local/zlib

Follow the given procedure above, except

…/zlib-1.2.1]# ./configure –prefix=/usr/local/zlib

Update the Run-Time Linker

/etc/ld.so. will need to be updated with the new zlib shared lib: libz.so.1.2.1

For standard zlib installation…

Add /usr/local/lib to /etc/ld.so.conf, if specified path is not present

/etc]# ldconfig

If zlib was installed with a prefix…

Add /usr/local/zlib/lib to /etc/ld.so.conf

/etc]# ldconfig

安装

Download

Home : http://www..org/

Package(source) : -0.9.7d.tar.gz

Our Configuration

install to : /usr/local/

module types : dynamically and staticly loaded modules, *.so *.a

Build Instructions

…/-0.9.7d]# ./config

–prefix=/usr/local/

[default location]

shared

[in addition to the usual static libraries, create shared libraries]

zlib-dynamic

[like "zlib", but has load the zlib library dynamically when needed]

…/-0.9.7d]# ./config -t

[display guess on system made by ./config]

…/-0.9.7d]# make

…/-0.9.7d]# make test

…/-0.9.7d]# make install

Update the Run-time Linker

ld.so. will need to be updated with the location of the new shared libs: libcrypto.so.0.9.7 and libssl.so.0.9.7

Sometimes it is sufficient to just add these two files to /lib, but we recommend you follow these instructions instead.

Edit /etc/ld.so.conf

Add /usr/local//lib to the bottom.

…]# ldconfig

Update the PATH

Edit /root/.bash_profile

Add /usr/local//bin to the PATH variable.

Re-login

Testing

…]# version

Should display 0.9.7d 17 Mar 2004

If an older version is shown, your system contains a previously installed .

Repeate the steps in Update the PATH, except place the specified location at the start of the PATH variable.

[the older , on most systems, is located under /usr/bin]

[the command 'which ' should display the path of the that your system is using]

/usr/local//bin]# ./ version should display the correct version.

但是我最后没有得到想要的结果,系统原来的还是没能卸载掉,我该怎么做那?我继续搜索资料,哈,幸运的我找了,在一个国内论坛上是这么说的

cd /usr/local//lib

ln -s libcrypto.so.0.9.7 libcrypto.so.2

ln -s libssl.so.0.9.7 libssl.so.2

//最后要刷新系统的动态连接库配置

echo /usr/local//lib >> /etc/ld.so.conf

ldconfig -v

这下子我豁然开朗,原来依赖的那2个文件是个软链接啊,我把它修改为我现在真正的库文件不是就行了吗?于是一顿忙碌后,我终于执行了 rpm -e -nodeps ,然后重新启动系统,一路运行下去,全是绿灯。一时间感觉自己好幸福啊

为了这个问题我查了国内的几个比较大的/网站都没找到资料,不过从这里http://bbs.netbuddy.org//737.还是找到了(国外的E文大概意思能看懂,但是查找起来还是没找到,也不知道这方面好点的网站),

OpenSSL相关命令(for Linux)详细介绍

Friday, September 21st, 2007

转至: http://.ixpub.net/8400463

加密算法:

对称加密算法:

DES、IDEA、RC2、RC4、AES、Skipjack ……

非对称加密算法:

RSA、DSA、DiffieHellman、PKCS、PGP ……

单向的HASH算法属于报文摘要算法,虽然有些也出自库。
命令操作:

1、生成普通私钥:
[weigw@TEST src]$ genrsa -out privatekey.key 1024

Generating RSA private key, 1024 bit long modulus ….++++++ …….++++++ e is 65537 (0×10001)

2、生成带加密口令的密钥:

[weigw@TEST src]$ genrsa -des3 -out privatekey.key 1024

Generating RSA private key, 1024 bit long modulus …………++++++ …………………++++++ e is 65537 (0×10001) Enter pass phrase for privatekey.key: Verifying - Enter pass phrase for privatekey.key:

在生成带加密口令的密钥时需要自己去输入密码。对于为密钥加密现在提供了一下几种算法:
-des encrypt the generated key with DES in cbc mode

-des3 encrypt the generated key with DES in ede cbc mode (168 bit key)

-aes128, -aes192, -aes256 encrypt PEM output with cbc aes

去除密钥的口令:
[weigw@TEST src]$ rsa -in privatekey.key -out

privatekey.key Enter pass phrase for privatekey.key: writing RSA key

通过生成的私钥去生成证书:

[weigw@TEST src]$ req -new -x509 -key privatekey.key -out cacert.crt -days 1095

You are about to be asked to enter information that will be incorporated into your certificate request.

What you are about to enter is what is called a Distinguished Name or a DN. There are quite a few fields but you can leave some blank For some fields there will be a default value, If you enter ‘.’, the field will be left blank.

—–

Country Name (2 letter code) [GB]:CN

State or Province Name (full name) [Berkshire]:beijing

Locality Name (eg, city) [Newbury]:beijing

Organization Name (eg, company) [My Company Ltd]:wondersoft

Organizational Unit Name (eg, section) []:develop

Common Name (eg, your name or your ’s hostname) []:WeiGW

Email Address []:weigongwan@sina.com

在生成证书的时候需要按照提示输入一些个人信息。

通过私钥生成公钥:

[weigw@TEST src]$ rsa -in privatekey.key -pubout -out pubkey.key writing RSA key

格式转换:(证书、私钥、公钥)(PEM <—–>DER)

[weigw@TEST src]$ x509 -in cacert.crt -inform. PEM -out cacert.der -outform. DER

[weigw@TEST src]$

[weigw@TEST src]$ rsa -in privatekey.key -inform. PEM -out privatekey.der -outform. DER

writing RSA key

[weigw@TEST src]$ rsa -pubin -in pubkey.key -inform. PEM -pubout -out pubkey.der -outform. DER

writing RSA key

从DER格式转换成PEM格式一样,就是把inform的格式改成DERoutform的格式改成PEM即可。

下面是一个服务器和客户端认证的证书、私钥生成方法:(.crt、client.crt、ca.crt)

第一步: 生成私钥

[weigw@TEST bin]$ genrsa -out .key 1024

Generating RSA private key, 1024 bit long modulus .++++++ ..
………++++++ e is 65537 (0×10001)

[weigw@TEST bin]$ genrsa -out client.key 1024

Generating RSA private key, 1024 bit long modulus …++++++ ……
……….++++++ e is 65537 (0×10001)

[weigw@TEST bin]$ genrsa -out ca.key 1024

Generating RSA private key, 1024 bit long modulus …….
..++++++ ………++++++ e is 65537 (0×10001)

[weigw@TEST bin]$

第三步: 申请证书(为请求文件签名)

[weigw@TEST bin]$ ca -in .csr -out .crt -cert ca.crt -keyfile ca.key

[weigw@TEST bin]$ ca -in client.csr -out client.crt -cert ca.crt -keyfile ca.key

如果在这步出现错误信息:

[weigw@TEST bin]$ ca -in client.csr -out client.crt -cert ca.crt -keyfile ca.key

Using configuration from /usr/share//.cnf I am unable to access the ./demoCA/newcerts directory ./demoCA/newcerts: No such file or directory

[weigw@TEST bin]$

自己手动创建一个CA目录结构:
[weigw@TEST bin]$ mkdir ./demoCA
[weigw@TEST bin]$ mkdir demoCA/newcerts
创建个空文件:
[weigw@TEST bin]$ vi demoCA/index.txt
向文件中写入01:
[weigw@TEST bin]$ vi demoCA/serial

合并证书文件(crt)和私钥文件(key):

[weigw@TEST bin]$ cat client.crt client.key > client.pem [weigw@TEST bin]$ cat .crt .key > .pem

合并成pfx证书:

[weigw@TEST bin]$ pkcs12 -export -clcerts -in client.crt -inkey client.key -out client.p12

Enter Export Password:

Verifying - Enter Export Password:

[weigw@TEST bin]$ pkcs12 -export -clcerts -in .crt -inkey .key -out .p12
Enter Export Password:
Verifying - Enter Export Password:

文本化证书:

[weigw@TEST bin]$ pkcs12 -in client.p12 -out client.txt Enter Import Password:

MAC verified OK

Enter PEM pass phrase: Verifying - Enter PEM pass phrase:

[weigw@TEST bin]$ pkcs12 -in .p12 -out .txt

Enter Import Password:

MAC verified OK

Enter PEM pass phrase: Verifying - Enter PEM pass phrase:

屏幕模式显式:(证书、私钥、公钥)

[weigw@TEST bin]$ x509 -in client.crt -noout -text -modulus

[weigw@TEST bin]$ rsa -in .key -noout -text -modulus

[weigw@TEST bin]$ rsa -in .pub -noout -text -modulus

得到DH:

[weigw@TEST bin]$ dhparam -out dh1024.pem 1024
