Android Network Programming Series 1: JavaSecurity JSSE (SSL/TLS), javasecurityjsseAbstractTo:Java Security has been in Java for a long time and is a very important and independent forum. It contains many knowledge points, such as MD5 and DigitalSignature. Android is outside Java Seurity, extended an android. security Package, which provides the KeyChain.

The default Fabric1.0.2 example is not based on TLS, but the Balance-transfer and e2e_cli examples are based on TLS, and in order to make the connection more secure and generic, the research supports the implementation of log monitoring based on TLS. The example/events/block-listener.go example in the Fabric1.0.2 source code produces the process of listening to t

Can you introduce the problems found in the RC4 encryption algorithm recently? In this regard, what security risks do HTTPS network connections face? How should enterprises ensure that they are not attacked by this vulnerability? Michael Cobb:RC4 (Rivest password 4) was designed by Ron Rivest of RSA Security in 1987. Due to its speed and simplicity, this encryption algorithm has become the most widely used stream password. It is used in common protocols, including Wired Equivalent Security (WEP)

First, the roleHTTP communications that do not use SSL/TLS are non-encrypted traffic. All information is transmitted in plaintext, potentially three major risks.1, eavesdropping risk (eavesdropping): Third party can learn the content of the communication.2. Tamper risk (tampering): Third parties may modify the content of the communication.3. Impersonation risk (pretending): A third party may participate in the communication by impersonating another pe

toolsFiddler accesses traffic on the PC as a proxy on the mobile phone side. Then Wireshark can crawl the request on the PC, so as to use Wireshark to grab the phone's request.The second type: Wireshark+tcpdump toolsOf course, we can also use the Tcpdump tool to directly grab the phone's request data, generally saved as pcap file format, and then on the PC side with the Wireshark to analyze the Pcap file format. About tcpdump how to grab a package to generate PCAP files, you can search by yours

I. The handshake process of SSL/TLS In the SSL/TLS handshake process, the client and the server need to exchange parameters, the specific process is as follows: The client provides the various cipher suites that it supports (including cryptographic algorithms and hash functions) from which the server chooses itself and supports cipher Suiteand notifies the client that both will be used for this data transfe

Three Windows Server SSL/TLS security vulnerabilities and their remedy Not long ago, the simple use of SSL on Windows servers, or its successor TLS, were considered safe communication methods. But now the era has changed, and SSL and TLS have become corrupted. In the past few years, many serious security vulnerabilities that are worth your attention have been exp
