查看 找回 SecureCRT的密码

原文地址：http://blog.csdn.net/nickwong_/article/details/52373279

打开SecureCRT程序中的 Data\Settings\Config\Sessions目录，会看到所有的回话 对应一个ini文件 如 192.168.8.10.ini

PyCharm 新建一个py脚本 SecureCRTDecrypt.py

    padded = c1.decrypt(c2.decrypt(password.decode('hex'))[4:-4])
    p = ''
    while padded[:2] != '\x00\x00' :
        p += padded[:2]
        padded = padded[2:]
    return p.decode('UTF-16')

parser.add_argument('files', type=argparse.FileType('r'), nargs='+',
    help='session file(s)')

    print f.name
    print "ssh %s%s%s # %s"%(port(c), username(c), hostname(c), password(c))
