加密算法與DNS服務搭建
-
一、 簡述常見加密算法及常見加密算法原理，最好使用圖例解說
常見加密算法：html
-
對稱加密：加密和解密使用同一個密鑰；
DES：Data Encryption Standard;
3DES：Triple DES;
AES：Advanced Encryption Standard; (128bits, 192bits, 256bits, 384bits)
Blowfish
Twofish
DEA
RC6
CAST5nginx
特性：
一、加密、解密使用同一個密鑰；
二、將原始數據分割成爲固定大小的塊，逐個進行加密；git
缺陷：
一、密鑰過多；
二、密鑰分發困難；web
-
公鑰加密：密鑰分爲公鑰與私鑰
公鑰：從私鑰中提取產生；可公開給全部人；pubkey
私鑰：經過工具建立，使用者本身留存，必須保證其私密性；secret key；
特色：用公鑰加密的數據，只能使用與之配對兒的私鑰解密；反之亦然；算法
用途：
數字簽名：主要在於讓接收方確認發送方的身份；
密鑰交換：發送方用對方公鑰加密一個對稱密鑰，併發送給對方；
數據加密數據庫
算法：RSA， DSA， ELGamal
DSS: Digital Signature Standard
DSA：Digital Signature Algorithmapache
-
單向加密：即提出數據指紋；只能加密，不能解密；
特性：定長輸出、雪崩效應；
功能：完整性；
算法：
md5：Message Digest 5, 128bits
sha1：Secure Hash Algorithm 1, 160bits
sha224, sha256, sha384, sha512 緩存 -
密鑰交換： IKE（Internet Key Exchange）
公鑰加密
DH（Deffie-Hellman）
A：p, g
B：p, g服務器A: x --> p^x%g ==> B A: (p^y%g)^x=p^yx%g B: y --> p^y%g ==> A B: (p^x%g)^y=p^xy%g

二、 搭建apache或者nginx並使用自簽證書實現https訪問，自簽名證書的域名自擬

CA主機上建立私有CAsession

into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.

If you enter '.', the field will be left blank.

三、簡述DNS服務器原理，並搭建主-輔服務器
-
DNS服務器原理：
DNS也就是Domain Name Service的縮寫，它的做用就是經過域名查找IP地址。DNS查詢的類型對DNS於客戶端來講是遞歸查詢，對於DNS服務器端來講，絕大多數是迭代查詢，在它的解析中，從名稱到IP的查詢叫作正向解析，而從IP到名稱的查詢叫作反向解析。若是DNS服務器至少解析了一個或一個以上的域叫作DNS主服務器或者DNS輔助服務器，若是不負責任何解析叫作DNS緩存服務器。現全球一共分佈了13臺DNS根服務器，名稱爲A至M。 -
域名解析過程：
- 客戶訪問時，查找本身的hosts文件，有則返回，無則查找DNS服務器。
2．DNS服務器查找中先從頂級域到二級域，分別獲取他們的IP地址，而後最終得到域名的IP地址，找到服務器。
- 客戶訪問時，查找本身的hosts文件，有則返回，無則查找DNS服務器。
- DNS區域數據庫文件：
資源記錄（resource record 簡稱rr）的類型有如下幾種：
SOA：起始受權記錄，只能有一個，必須放在第一條
NS：域名服務記錄，其中一個爲主，能夠有多個
A：IPV4地址記錄
AAAA：IPV6地址記錄
CNAME：別名記錄
PTR：反向解析記錄
MX：郵件交換器
搭建主-輔服務器
安裝軟件
[root@localhost ~]# yum -y install bind [root@localhost ~]# yum -y install bind-utils [root@localhost ~]# systemctl start named [root@localhost ~]# netstat -tunlp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 127.0.0.1:53 0.0.0.0:* LISTEN 9952/named tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 960/sshd tcp 0 0 127.0.0.1:953 0.0.0.0:* LISTEN 9952/named tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1099/master tcp6 0 0 ::1:53 :::* LISTEN 9952/named tcp6 0 0 :::22 :::* LISTEN 960/sshd tcp6 0 0 ::1:953 :::* LISTEN 9952/named tcp6 0 0 ::1:25 :::* LISTEN 1099/master udp 0 0 127.0.0.1:53 0.0.0.0:* 9952/named udp6 0 0 ::1:53 :::* 9952/named

修改DNS的named.conf的配置文件
view internal {
match-clients { 192.168.10.10; };
zone "." IN {
type hint;
file "named.ca";
};
include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";

view external {
match-clients { any; };
zone "." IN {
type hint;
file "named.ca";
};
include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";
};
