OpenSSL证书认证过程
OpenSSL证书认证过程游戏服务端这块,之前是很少⽤SSL的,毕竟游戏⾥的数据没有什么保密的必要,登录、充值也是传输签名,不涉及密码什么的。
不过这⼏年,HTTPS普及得⽐较快,H5游戏发展迅速。
H5游戏是基于web的,和后端通信⼀般⾛websocket,加不加SSL其实对于游戏影响不⼤。
但是不少平台都要求加SSL的,⼀是⽤户通过浏览器玩游戏时,地址栏⾥有个锁头体验还是好点,⼆是丧⼼病狂的⿊产会劫持链接加上⼴告,想象⼀下在玩游戏时,右下⾓弹个⼴告是啥体验。
虽说⽤上SSL,不过并不⼀定就要⾃⼰实现SSL,⽐如⽤Nginx做⼀层代理,在Nginx处理SSL,在游戏服务器处理逻辑。
不过最近有时间,还是研究下SSL。
这⾥不涉及如何⽤OpenSSL实现⼀个SSL链接,⽹上的例⼦已经太多。
⽽是研究下证书的认证,即浏览器地址栏⾥的这个锁头是怎么来的?它怎么判断当前连接是安全?这⾥以OpenSSL为例,简单说下SSL的的建⽴过程。
普通的socket通过accept/connect来建⽴连接,然后⽤SSL_set_fd把socket和OpenSSL关联起来,接着调⽤SSL_do_handshake来进⾏SSL握⼿,握⼿成功后,就可以通过SSL_read/SSL_write来进⾏加密的数据通信。
那证书的认证在哪⾥处理?证书认证属于SSL握⼿(SSL_do_handshake)的⼀部分,SSL连接分为⼆种:1. 单向认证客户端认证服务端,服务端不认证客户端,这时服务端需要⼀个证书,客户端不需要。
⽹站的HTTPS认证通常属于这⼀类,即⽹站的内容是公开的,它并不在意谁来访问这些内容,因此⽆需校验客户端。
但对客户端⽽⾔,它要保证所访问的⽹站是正确的⽹站,⽽不是被劫持修改、假冒的钓鱼⽹站,因此需要校验服务端。
2. 双向认证客户端认证服务端,服务端也需要认证客户端,这时候服务端和客户端都需要有证书。

at and what they need to practice more. Remember, “use it or lose it”! Even if you learn something well, you will forget it unless you use it. “Practice makes perfect.” Good learners will keep practicing what they have learned, and they are not afraid of making mistakes. Alexander Graham Bell did not invent the telephone overnight. He succeeded by trying many times and learning
Creating an interest in what they learn
it is also easier for you to pay attention to it for a long time. Good learners often connect what they need to learn with something interesting. For example, if they need to learn English and they like music or sports, they can listen to English songs or watch sports programs in English. This way they will not get bored.

Never install the product in wet locations or during lightning storms. Never touch uninsulated communication wires or terminals.• All wiring that connects to this equipment must meet applicable local and national building codes and network wiring standards for communication cable.• iPatch upgrade modules use infrared sensing technology and should be installed where they are not exposed to direct sunlight or other infrared sources.Save these instructions.OverviewTo prepare panels for use with an iPatch System, you must perform the following steps: Step 1 – Mount a panel bus for the rack.Step 2 – Install an iPatch manager to supervise the rack. Step 3 – Connect each panel to the panel bus. Step 4 – Program the order of the panels in the rack.Step 1 – Mount the Panel BusA panel bus must be installed on each rack where you plan to iPatch install panels. The panel bus allows the iPatch Manager and iPatch panels to communicate. Also, the iPatch Manager supplies power to the iPatch panels through the panel bus.The panel bus must be installed to the left on the rack (viewed from the front). The preferred location is the back corner of the rack’s left rail. The area where the panel bus will be mounted must be free of protrusions, such as threaded inserts, nuts, and bolts.To mount the panel bus on a rack other than a 7-foot (2.1m) rack or on a rack with a hole pattern other than the universal hole pattern, contact your local account representative.For instructions to install the panel bus for the rack, see the SYSTIMAX ®iPatch System Panel Manager Guide (860442573). 860536390Issue 3, November 2012 Step 2 – Install the iPatch ManagerAn iPatch manager must be installed on each rack where you plan to install panels. The iPatch manager supervises the iPatch panels in the rack and communicates with the iPatch System.CommScope recommends mounting the panel manager in the 34th 1U slot up from the bottom of the rack so that the top of the unit is about 65 inches (1.6m) above the floor. For instructions to install and configure the panel manager, see the SYSTIMAX iPatch System Panel Manager Guide (860442573)Step 3 – Connect Panels to the Panel BusTo connect each panel to the panel bus, perform the following steps:1. Position a cable retainer on the panel bus jumperas shown (Figure 1) and remove the adhesivebacking from the cable retainer.Figure 1.2. Connect the panel bus jumper to the nearestconnector on the panel bus, folding the jumperas shown (Figure 2). Press the cable retaineragainst the rack.Note: The connector is keyed. The polarized tabon the jumper connector fits into theopening in the header connector on thepanel bus.Important: For 48-port panels, connect bothpanel bus jumpers.Figure 2.Step 4 – Program the Order of PanelsTo complete the installation, restore power to the panel manager for the rack and program the order of the panels. For instructions, see the SYSTIMAX iPatch System Panel Manager Guide (860442573).Page 3 of 3。

ABAPRSA加密
ABAPRSA加密最近出现⼀些SAP ABAP RSA加密的需求,这⾥搬运⼀篇⽂章,⽤于学习参考。
原⽂标题:最近我偶然在SAP社区发现了很多关于RSA加密的未解答的问题。
在这⾥我将尝试提供⼀些例⼦,说明如何在ABAP中使⽤公钥/私钥加密。
所有的间接问题,如证书、信任、撤销和密钥⽣成,在本⽂中不会涉及。
密钥将⽤openssl⽣成。
例⼦1 – ⽤⾃⼰的ABAP RSA实现RSA加密是⾮常简单的。
只需要整数算术--主要是模幂运算。
唯⼀的问题是,所涉及的整数⽐ABAP和⼤多数其他语⾔默认能处理的长。
幸运的是,这个问题被Harry Boeck⽤Z04_BIGINTX类解决了,可以(出⾊的⼯作)。
备注:评论区提到另⼀个解决⽅案。
⽣成RSA key创建⼀个⼯作⽬录,并进⼊,mkdir -p /tmp/rsacd /tmp/rsa⽣成2048位RSA密钥。
/tmp/rsa > openssl genrsa -out rsa.key 2048Generating RSA private key, 2048 bit long modulus (2 primes) .....................................................................+++++.......+++++e is 65537 (0x010001)⽤纯⽂本输出公钥和私钥。
我们只需要模数(modulus)、公钥指数(publicExponent)和私钥指数(privateExponent)。

北斗短报文语音模块BDYY系列串口通信协议用法举例
北斗短报文语音模块BDYY系列串口通信协议用法举例(北京太和宝业科技有限公司)2014年12月25日针对BDYY系列北斗短报文语音模块串口通信协议,现以300 bit压缩率、短卡容量为78个字节、一次最多发送4条短信数据量的模块为例,解读如下:一、发送例1,BDYY传出一条语音数据内容为:30 30 B2 F1 E4 D3 35 D0 4F 53 24 30 8A 02 3D 76 60 ED 20 2E FF FF(内容为:您好)(注意上面涂红色的30 30和涂蓝色的FF FF)北斗收发设备从串口读取该数据。
开头的连续两个30 ,一是说明这是300bit 压缩率的语音数据,二是说明这是一条语音短信的开始标记。
结尾的FF FF ,说明这是语音数据结束标记。
用户收发设备在收到该数据后,在软件处理上去掉短信开头的30 30 和结尾的FF FF 后,再将该短信发送出去。

Power Measurements on Pulsed Signals
3 Peak- and Mean Power Measurement
Modern spectrum analyzers display the frequency spectrum or the waveform of a signal in the time domain using a raster scan cathode ray tube (CRT) or a liquid crystal display (LCD). Characteristic for these displays is that the number of pixels in the level axis as well as in the frequency or time axis is limited. This leads to limited resolution for both level and frequency or time. To display the full amount of measurement data taken in a sweep, detectors are used to compress the data samples into the number of displayed pixels. For the measurement of peak power, the spectrum analyzer offers a peak detector. The peak detector will display the highest peak within the measurement interval. For the mean power measurement of amplitude modulated signals (like pulse modulation) the peak detector commonly used in spectrum analyzers is not appropriate, as the peak voltage is not related to the power of the signal. For power measurements the spectrum analyzers provides the sample detector or the RMS detector. The following figure gives an overview of the difference of the detector results on a symbolic graph:

2 Requirements
Modern radar applications use continuously changing pulse parameters. The pulse width and pulse repetition frequency is not constant and depends on the radar mode. Due to these changing parameters, the calculation of peak power from mean power as measured with a power meter is not possible anymore. This application note shows how the measurement of peak power and mean power on these changing signals can be made with modern spectrum analyzers. Additionally the measurement of mean power over a long time frame is explained. This is a very important measurement in the antenna field of radar transmitters for the protection against personal injury due to high power transmission, especially while the antenna is rotating.

Power Measurement on Pulsed Signals with Spectrum Analyzers
Application Note
This application note provides information about measurements on pulsed signals with a spectrum analyzer. Examples show the practical realisation of measurements like pulse width, peak power and mean power, and the limitations of spectrum analyzer measurements. A method for long time average power measurement is explained.

1 Overview
A spectrum analyzer is an important instrument for measurements on radar signals. Many of the different parameters of a radar signal, like carrier frequency, occupied spectrum, carrier ON/OFF ratio, pulse repetition frequency, rise-/fall-time, phase noise and peak power, can be directly measured with a spectrum analyzer. Testing for output power is one of the important measurements on radar transmitters. For output power on a pulsed signal such as radar there are several different types of power measurements. Average power is one of the common measurements usually made as mean power measurements with power meters. Another very important value is peak power. With the knowledge of the Pulse Repetition Frequency (PRF) and the pulse width, one can calculate the peak power from the measured mean power. This function is available in many power meters. This application note explains the use of the Rohde & Schwarz FSP spectrum analyzer family for the measurement of peak power and mean power on pulse modulated signals. The knowledge about pulse parameters of the radar is not necessary for this measurement. The recommended setups are supported by example measurements on a radar signal simulated by a signal generator.
