Using Unsniff Network Analyzer to Analyze SSL / TLS
Whitepaper – SSL / TLS Analysis using Unsniff Network Analyzer Whitepaper : Using Unsniff Network Analyzer to analyze SSL / TLS A number of applications today use SSL and TLS as a security layer. Unsniff allows authorized users to analyze these applications by decrypting the SSL/TLS streams in real time. This is done without interrupting the SSL streams in any way. Unsniff can also strip out the SSL/TLS layer completely and analyze the application protocols as if the security layer never existed. For example: If you are working with a secure web server, you can analyze the HTTPS protocol, including the ability to reconstruct complete web pages. References : RFC2246 (TLS 1.0), RFC2459 (X.509v3), PKCS Standards (RSA Website) Feature overview Working with PDUs and Streams Decrypting SSL/TLS Analyzing upper layer protocols Howto : Analyzing a secure Microsoft IIS web server Howto : Analyzing a secure Apache web server Howto : Analyzing protocols tunneled via stunnel FAQ 1/12 © Unleash Networks, All rights reserved Whitepaper – SSL / TLS Analysis using Unsniff Network Analyzer Feature Overview Unsniff shows SSL/TLS records as separate entities in the PDU sheet irrespective of SSL records how they were carried at the link layer. Stream Monitor entire SSL / TLS sessions in real time via the Streams sheet. analysis Provided you have the servers private key material you can decrypt SSL / TLS Decryption sessions in real time. Most of the popular ciphers are supported. Advanced Unsniff supports SSL / TLS features such as session reuse and cipher renegotiation. Decryption SSL/TLS only acts as a transport layer for higher layer protocols. Ultimately we are interested in the analysis of higher layer protocols such as HTTP, LDAP etc. -

Difference Between Perl and Python Key Difference
Difference Between Perl and Python www.differencebetween.com Key Difference - Perl vs Python A computer program provides instructions for a computer to perform tasks. A set of instructions is known as a computer program. A computer program is developed using a programming language. High-level languages are understandable by programmers but not understandable by the computer. Therefore, those programs are converted to machine-understandable format. Perl and Python are two high-level programming languages. Perl has features such as built-in regular expressions, file scanning and report generation. Python provides support for common programming methodologies such as data structures, algorithms etc. The key difference between Perl and Python is that Perl emphasizes support for common application-oriented tasks while Python emphasizes support for common programming methodologies. What is Perl? Perl is general purpose high-level programing language. It was designed by Larry Wall. Perl stands for Practical Extraction and Reporting Language. It is open source and is useful for text manipulation. Perl runs on various platforms such as Windows, Mac, Linux etc. It is a multi-paradigm language that supports mainly procedural programming and object-oriented programming. Procedure Programming helps to divide the program into functions. Object Oriented programming helps to model a software or a program using objects. Perl is an interpreted language. Therefore, each line is read one after the other by the interpreter. High-level language programs are understandable by the programmer, but they are not understandable by the machine. Therefore, the instructions should be converted into the machine-understandable format. Programming languages such as C and C++ converts the source code to machine language using a compiler.
