Fabric1.0.2 implementation of log monitoring based on TLS connection

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

RC4 attacks: Can RC4 encryption algorithms protect SSL/TLS?

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)

Overview of the operating mechanism of the SSL/TLS protocol (reprint plus personal understanding)

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

Android Black Tech series--wireshark and fiddler analysis of TLS protocol package data in Android (with case samples)

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
