Now there are many of the company's website is HTTPS encryption, not long ago, my site has just been wosign detected a loophole, https://wosign.ssllabs.com/, this is the detection of the Web site. What is the impact of this vulnerability,Baidu is a loophole in the key words to be good.First, the vulnerability650) this.width=650; "Src=" Http://s1.51cto.com/wyfs02/M02/87/F0/wKioL1fknwaAZ3VgAAA66RXacdo940.png-wh_500x0-wm_3 -wmp_4-s_1126777209.png "title=" 1.png "alt=" Wkiol1fknwaaz3vgaaa66rxacdo940
Post an informed answer:
There is also a service that tests whether the Web site is affected: Test your server for Heartbleed (cve-2014-0160) (now long 503)
According to the description on the page, this OpenSSL implementation vulnerability can obtain the sensitive memory data on the host in the handshake phase, even including the SSL certificate private key! The loophole appeared in 2012 and was only recently repaired yesterday (April 7, 2014). To

OpenSSL symmetric encryption algorithm commands
1. symmetric encryption algorithm Overview
The openssl Encryption Algorithm Library provides a wide range of symmetric encryption algorithms. We can use the symmetric encryption algorithm commands provided by openssl, or call the APIS provided by openssl.

To generate a certificate in OpenSSL, follow these steps:1. generate an RSA private key file and generate a certificate application for this private key file.First, you must enter a password to encrypt the RSA private key file and ask the user to confirm the password. Then, the user is required to enter the user's information for the certificate application file, such as the country, region, city, and name of the user (the remaining information is opt
I. Introduction of OpenSSL
OpenSSL is currently the most popular SSL cipher library tool that provides a common, robust, and fully functional suite of tools to support the implementation of the SSL/TLS protocol.Official website: https://www.openssl.org/source/ component cipher algorithm library key and certificate encapsulation management function SSL Communication API Interface use establish RSA, DH, DSA k
Transferred from: http://netsecurity.51cto.com/art/201301/378513.htm1. IntroductionOpenSSL is a powerful cryptographic toolkit. Many of us already use OpenSSL to create RSA private keys or certificate signing requests (CSRs). But have you ever known that you can use OpenSSL to test your computer's speed? Or can you use it to encrypt a file or a message? This article will show you a few easy-to-learn tips on

OpenSSL is a hot spot in the dark. At first, several small business machines of the company's rds were notified to fix the OpenSSL vulnerability. These machines were all independent small businesses and were stopped, after finding a simple document, upgrade it to OK (some are nginx, some are resin ). After the service is restarted, OK.
The company's main business also has a general portal machine (two machi

3. Another purpose of Security Authentication Encryption is to serve as a personal identity, and the user's key can be used as the identity for security authentication. SSL uses public key encryption technology (RSA) as the encrypted communication protocol between the client and the server when transmitting confidential data.
