我想帮你分解你正在看的东西。
如果你拿你的base64字符串：
+ / / 3J + skZ6UtW +
然后将其解码为十六进制：
30 81 9F 30 0D 06 09 2A 86 48 86 F7 0D 01 01 01
05 00 03 81 8D 00 30 81 89 02 81 81 00 AA 18 AB
A4 3B 50 DE EF 38 59 8F AF 87 D2 AB 63 4E 45 71
C1 30 A9 BC A7 B8 78 26 74 14 FA AB 8B 47 1B D8

A7 41 9B 30 90 F2 47 87 BD 4F 4E 19 67 02 03 01
00 01
所以问题是：这是什么？那实际上是ASN.1编码的DER变体。ASN.1是一个可怕的怪物，但价值实际上是这样的：
30 81 9F ;30=SEQUENCE (0x9F = 159 bytes)
| 30 0D ;30=SEQUENCE (0x0D = 13 bytes)

| | 02 03 ;02=INTEGER (0x03 = 3 bytes) - the exponent

所以编码在十六进制中有两个重要的数字：
指数：（65537 几乎每个人普遍使用65,537作为主要指数）
模数：00 AA 18 AB A4 3B 50 DE EF 38 59 8F AF 87 D2 AB 63 4E 45 71 C1 30 A9 BC A7 B8 78 26 74 14 FA AB 8B 47 1B D8 96 5F 5C 9F C3 81 84 85 EA F5 29 C2 62 46 F3 05 50 64 A8 DE 19 C8 C3 38 BE 54 96 CB AE B0 59 DC 0B 35 81 43 B4 4A 35 44 9E B2 64 11 31 21 A4 55 BD 7F DE 3F AC 91 9E 94 B5 6F B9 BB 4F 65 1C DB 23 EA D4 39 D6 CD 52 3E B0 81 91 E7 5B 35 FD 13 A7 41 9B 30 90 F2 47 87 BD 4F 4E 19 67
或者，在十进制中，你的模数是：
119,445,732,379,544,598,056,145,200,053,932,732,877,863,846,799,652,384,989,588,303,737,527,328,743,970,559,883,211,146,487,286,317,168,142,202,446,955,508,902,936,035,124,709,397,221,178,664,495,721,428,029,984,726,868,375,359,168,203,283,442,617,134,197,706,515,425,366,188,396,513,684,446,494,070,223,079,865,755,643,116,690,165,578,452,542,158,755,074,958,452,695,530,623,055,205,290,232,290,667,934,914,919
3. 什么叫CA注册会计师,孩子在加拿大多伦多考取了这个牌照(证书),请老师们解释一下详细答案,谢谢啦!
你说的是CPA吧？certified public accountant,中文是注册会计师。这个是会计师执照。
4. 中国网银USBKey数字安全证书管理工具改了密码再次登录就都不对了
实在不行就持身份证和法人身份证到中行网点进行usbkey密码重置。
望采纳！
5. caof是全钙的符号吗
氢氧化钙，溶度积是5.2*10-6要加不用，因为反应物中氧化钙也为固体。打沉淀符号的前提是反映在液体或溶液之间进行的，所以这个反应中产物是沉淀也不加沉淀符号。同样，如果反应物里面有气体的话，即使生成物中有气体也不用打气体符号
6. 英语：CA是什么全称
一般指证书颁发的机构
Certification Authority
7. 开机不要启动中行网银USBKey数字安全证书管理工具
1、中行网银USBKey数字安全证书管理工具有什么用...BOC OF CHINA 3、是不是浏览器的...建议还是使ie浏览器进行支付交易，另外应该下载网银客户端安装好网银驱动
8. Ofca是什么标志
OFCA认证是香港电讯管理局对香港地区通信产品认证计划的简称。香港电信管理局规定，凡经过测试并符合相关技术规格的电信设备并获该局授予证书后，方可在香港出售和使用。从今年2月起，香港生产力促进局（HKPC）正式成为香港电讯管理局（OFCA）授权的认证机构，并代表香港电信管理局对在本港使用或销售的电信设备提供认证服务。
9. 签名证书与自签名证书的区别
签名证书：由权威颁发机构颁发给服务器或者个人用于证明自己身份的东西，默认客户端都是信任的。主要目的是用来加密和保证数据的完整性和不可抵赖性
自签名证书：由服务器自己颁发给自己，用于证明自己身份的东西，非权威颁发机构发布，默认客户端都是不信任的，主要目的是用来加密和保证数据的完整性和不可抵赖性,与签名证书相同.
详细具体解释见下面英文。
When you're building an ecommerce site one of the first things you'll need to set up is a security certificate so that your server data will be secure. When you set this up, you have the option of creating a self-signed cerficate or creating a certificate approved by a certificate authority.
Similarities Between Signed and Self-Signed Certificates
Whether you get your certificate signed by a certificate authority or sign it yourself, there is one thing that is exactly the same on both:
Both certificates will generate a site that cannot be read by third-parties. The data sent over an https connection or SSL, will be encrypted regardless of whether the certificate is signed or self-signed.
In other words, both types of certificates will encrypt the data to create a secure website.
Then Why Pay a Certificate Authority?
A certificate authority tells your customers that this server information has been verified by a trusted source. The most commonly used Certificate Authority is Verisign. Depending upon which CA is used, the domain is verified and a certificate is issued. Verisign and other more trusted CAs will verify the existence of the business in question and the ownership of the domain to provide a bit more security that the site in question is legitimate.
The problem with using a self-signed certificate is that nearly every Web browser checks that an https connection is signed by a recognized CA. If the connection is self-signed, this will be flagged as potentially risky and error messages will pop up encouraging your customers to not trust the site.
When Can You Use a Self-Signed Certificate?
Since they provide the same protection, you can use a self-signed cerificate anywhere you would use a signed certificate. But some places work better than others.
Self-signed certificates are great for testing servers. If you're creating a website that you need to test over an https connection, you don't have to pay for a signed certificate for that testing site. You just need to tell your testers that their browser may pop warning messages.
You can also use self-signed certificates for situations that require privacy, but people might not be as concerned about. For example:
Username and password forms
Collecting personal (non-financial) information
On forms where the only users are people who know and trust you
What it comes down to is trust. When you use a self-signed certificate, you are saying to your customers "trust me - I am who I say I am." When you use a certificate signed by a CA, you are saying, "Trust me - Verisign agrees I am who I say I am."
If You're Doing Ecommerce You Need a Signed Certificate
While it is possible your customers will forgive you a self-signed certificate if all they use it for is to login to your website. But if you're asking them to input their credit card or Paypal information, then you really need a signed certificate. Most people trust the signed certificates and won't do business over an HTTPS server without one. So if you're trying to sell something on your website, invest in that certificate. It's just a cost of doing business.
