我想幫你分解你正在看的東西。
如果你拿你的base64字元串：
+ / / 3J + skZ6UtW +
然後將其解碼為十六進制：
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
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 02 03 01
00 01
所以問題是：這是什麼？那實際上是ASN.1編碼的DER變體。ASN.1是一個可怕的怪物，但價值實際上是這樣的：
30 81 9F ;30=SEQUENCE (0x9F = 159 bytes)
| 30 0D ;30=SEQUENCE (0x0D = 13 bytes)
| | 06 09 ;06=OBJECT_IDENTIFIER (0x09 = 9 bytes)
| | 2A 86 48 86 ;Hex encoding of 1.2.840.113549.1.1

| | 05 00 ;05=NULL (0 bytes)
| 03 81 8D 00 ;03=BIT STRING (0x8d = 141 bytes)
| | 30 81 89 ;30=SEQUENCE (0x89 = 137 bytes)
| | | 02 81 81 ;02=INTEGER (0x81 = 129 bytes) the molus

| | | 35 FD 13 A7 41 9B 30 90 F2 47 87 BD 4F 4E 19 67
| | 02 03 ;02=INTEGER (0x03 = 3 bytes) - the exponent
| | | 01 00 01 ;hex for 65537
所以編碼在十六進制中有兩個重要的數字：
指數：（65537 幾乎每個人普遍使用65,537作為主要指數）
模數：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，在十進制中，你的模數是：
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. 什麼叫CA注冊會計師,孩子在加拿大多倫多考取了這個牌照(證書),請老師們解釋一下詳細答案,謝謝啦!
你說的是CPA吧？certified public accountant,中文是注冊會計師。這個是會計師執照。
4. 中國網銀USBKey數字安全證書管理工具改了密碼再次登錄就都不對了
實在不行就持身份證和法人身份證到中行網點進行usbkey密碼重置。
望採納！
5. caof是全鈣的符號嗎
氫氧化鈣，溶度積是5.2*10-6要加不用，因為反應物中氧化鈣也為固體。打沉澱符號的前提是反映在液體或溶液之間進行的，所以這個反應中產物是沉澱也不加沉澱符號。同樣，如果反應物裡面有氣體的話，即使生成物中有氣體也不用打氣體符號
6. 英語：CA是什麼全稱
一般指證書頒發的機構
Certification Authority
7. 開機不要啟動中行網銀USBKey數字安全證書管理工具
1、中行網銀USBKey數字安全證書管理工具有什麼用...BOC OF CHINA 3、是不是瀏覽器的...建議還是使ie瀏覽器進行支付交易，另外應該下載網銀客戶端安裝好網銀驅動
8. Ofca是什麼標志
OFCA認證是香港電訊管理局對香港地區通信產品認證計劃的簡稱。香港電信管理局規定，凡經過測試並符合相關技術規格的電信設備並獲該局授予證書後，方可在香港出售和使用。從今年2月起，香港生產力促進局（HKPC）正式成為香港電訊管理局（OFCA）授權的認證機構，並代表香港電信管理局對在本港使用或銷售的電信設備提供認證服務。
9. 簽名證書與自簽名證書的區別
簽名證書：由權威頒發機構頒發給伺服器或者個人用於證明自己身份的東西，默認客戶端都是信任的。主要目的是用來加密和保證數據的完整性和不可抵賴性
自簽名證書：由伺服器自己頒發給自己，用於證明自己身份的東西，非權威頒發機構發布，默認客戶端都是不信任的，主要目的是用來加密和保證數據的完整性和不可抵賴性,與簽名證書相同.
詳細具體解釋見下面英文。
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.
