1. UnixMD5技巧
有很多情况下我们需要通过最简单的办法来使用一小段程序运算出Unix的密码MD5后的字符串出来。这个Tips将我们所知道的各种简单办法列出来,希望对大家有所帮助。
1.1. PHP
<?php $MyPassword = "pass"; echo crypt($MyPassword); ?>
1.2. Perl
perl -e 'print crypt("passwd","\$1\$randstr\$"),"\n"'
1.3. Python
pw=pass python -c "import crypt;print crypt.crypt('"$pw"','py')"
1.4. C++

这个只是for FreeBSD 5。使用下面的命令进行编译后运行:
c++ -o maildb -O -pipe maildb.cpp -lcrypt
