Linux Intro: Signing and verifying data using GPG
 
08:31
In this video we will be using GPG to sign and verify data. Signing is used as a secure way to check whether data has been modified from the time of signing. We sign the data with our private key. Other users can verify the data and signature by using your public key. We are using Ubuntu Linux with the default install of GPG. Private keys were already generated.

Create Your Own Self Signed X509 Certificate
 
07:30
In this WiBisode Kevin will show how you can create signing certs for creating digital signatures! This is most often used to "lock" documents in a particular state, and then verified by the consuming application. The point of digital signatures is to create an application "trust" between two entities. When the consumer receives the document, it can validate the signature against the public key and feel confident that the document was "signed" by a trusted private key. #WiBisode #SelfSignedCertificate #SelfSigned #Certificate #OpenSSL #WiBitNet

How To Generate A Password Hash With Salt Via the Command OpenSSL On Linux For security reasons, you may want to store passwords in hashed form. This guards against the possibility that someone who gains unauthorized access to the database can retrieve the passwords of every user in the system. Hashing performs a one-way transformation on a password, turning the password into another String, called the hashed password. 🌸 Support channel & make donation : https://www.paypal.me/aminenina/5 🌸 Subscribe for more videos : Youtube: https://www.youtube.com/user/aminosninatos 🌸 Follow me On Social Media Facebook : https://www.facebook.com/aminosninatos/ *********************************************************************** 🌸 How To Convert Public Private Putty's ppk Keys To OpenSSH Keys On Ubuntu Linux https://youtu.be/3aApOFQL44o 🌸 How To Use GPG Private Public Keys To Encrypt And Encrypt Files On Ubuntu Linux https://youtu.be/I-4dcpTDWys 🌸 How To Encrypt And Decrypt Files Using Private Public Keys With OpenSSL On Ubuntu Linux https://youtu.be/g9XN1-bANKU 🌸 How To Encrypt And Decrypt Files Using OpenSSL On Ubuntu Linux https://youtu.be/YU1AI62khIY 🌸 How To Use MD5SUM To Verify Data Integrity On Ubuntu Linux https://youtu.be/V1fgjXRFB2k 🌸 How To Generate Random Password From The Command Line On Ubuntu Linux https://youtu.be/TQ4QMJWVd8U 🌸 Linux How To Crack And Recover A Password Protected Zip File https://youtu.be/C9a6BPxUN_4 🌸 Password cracking with John the Ripper on Linux https://youtu.be/KK2bNgX1mRA 🌸 Linux : HowTo Encrypt And Decrypt Files With A Password using GPG https://youtu.be/a91v1bz_ZU4 🌸 How To Secure Copy Files In Linux Using SCP Command https://youtu.be/3Y8pVDhc3RQ 🌸 How To Sync And Backup Files In Linux Using Rsync Command https://youtu.be/aIMbg7vG6Rg ***********************************************************************

How To Find out The Real Type Of a File Without an Extension using File Signatures
 
05:17
How To Find out The Real Type Of a File Without an Extension using File Signatures. Many, though certainly not all, files begin with a series of fixed values that identify the type of file that they are. "Naturally, there is no definitive list of what files have what signatures." A great example is the .EXE file. All .EXE files begin with two bytes: 4D, 5A. That's the hex value. Similarly, many other file types have these so called "signatures" as well. Our goal will be to examine the first few bytes of a file using a hex editor and then use what we find there to see if we can determine the file format. 🌸 Support channel & make donation : https://www.paypal.me/aminenina/5 🌸 Subscribe for more videos : Youtube: https://www.youtube.com/user/aminosni... 🌸 Follow me On Social Media Facebook : https://www.facebook.com/aminosninatos/ *********************************************************************** 🌸 Introduction To Packers What They Are Used For And How To Use Them https://youtu.be/GWYW66Y9z0c 🌸 How To Reverse Engineer A File Archiver Example WinRAR This Tutorial Is For Educational Purpose Only https://youtu.be/XgXLYjmmyZA 🌸 How To Find Out The True Creation Date Or the Timestamp Of A Windows Application https://youtu.be/XgXLYjmmyZA 🌸 How To Use a Hex Editor To Analyze A Bit Shifted File https://youtu.be/jrmn-jkszH0 🌸 How To Find out The Real Type Of a File Without an Extension using File Signatures https://youtu.be/OXTexpjVGJc 🌸 How to make the Simplest and Smallest Computer Virus in the World https://youtu.be/r8Jcq-ycS74 🌸 Reverse Engineering an Application and Bypass the Password Protection https://youtu.be/VuigVtcryas 🌸 How To Use Notepad++ As A Hex Editor https://youtu.be/_f1PDl1TynE 🌸 BGINFO - display relevant information about a Windows computer https://youtu.be/71Wn8BHDT_Y 🌸 How to Recover Deleted Files Using Recuva https://youtu.be/Iye-r52o3Fk 🌸 Hide your message inside an Image https://youtu.be/ulVgYUxnFkI ***********************************************************************

Empowering X.509 Certificate Management with Python
 
31:07
Marlon Dutra https://2016.pycon-au.org/schedule/68/view_talk Today, more than ever before, security is part of the fabric of the internet, with most websites defaulting to https over the historically used default of unsecured http. Whenever you see a URL starting with https:// (https:), your browser is sending the HTTP (or Spdy) traffic through a Transport Layer Security (TLS) tunnel. Part of establishing this secure tunnel involves your browser validating an X.509 certificate provided by the website you're viewing. This allows you to be sure that the server on the other end is who it says it is before you send some potentially sensitive information like your username and password. This is just one example of how these technologies can be used, but there are many more. In distributed systems that communicate sensitive information, like user data, it is imperative to have a mutual authentication mechanism, where the client is confident it is talking to the right service, as well as the service being confident it is talking to the right client. Beyond strong authentication, it is usually desirable to have some authorization logic, to prevent clients from having unrestricted access to all services. Since any TCP communication can be tunneled through TLS, and TLS supports such mutual authentication through X.509 certificates, they are the perfect set of tools for the job. The problem to solve then becomes how you manage all of these certificates. Crafting simple certificates with the openssl command line is a bit tricky but doable. However, modern certificates support a variety of advanced features and it is quite complicated to take full advantage of them through the command line, especially in a programmatic way. This is where Python can be a powerful tool. Through the use of certain libraries, you can inject valuable information into your certificates that can be used for many purposes, such as establishing a robust authorization model for a service. In this session we'll explore some of the ways you can leverage X.509 certificate features to better protect your systems and data. We'll give specific examples of how to use Python for the programmatic management of complex certificates as well as talking about how the largest website on the Internet, Facebook, handles hundreds of thousands of such certificates in its internal infrastructure, using these same approaches. By the end of this talk, you will understand how to craft your own elaborate certificates with Python and how to use them to secure communications between networked services.

Using MD5/SHA256 Hashes to Verify File Integrity
 
07:45
Windows PowerShell command: Get-FileHash [-Algorithm MD5] .\filename Remove the bracket if you want to use MD5 instead of the default SHA256. Make sure you are either navigated to your desired file’s directory using the “cd” command or you input the full path to the file. A full path looks like “C:\Program Files\Mozilla\firefox.exe” and a ‘current directory’ file has to have the “.\” appended to the filename. In the years that I have spent downloading files from the internet, I have learned that it is important to check the integrity of major files. The common user does not know and understand hashing, but this isn't your Grandma's house.

TPM2.0 practical usage Using a firmware TPM 2.0 on an embedded device
 
14:21
by Davide Guerri At: FOSDEM 2017 Nowadays Trusted Platform Module is present in most computers, and it ismaking its way into embedded platforms as well. In this talk I will explainhow to use the (firmware)TPM2.0 available on the Minnowboard MAX/Turbot (seealso https://fb.me/MinnowBoardMax and https://fb.me/MinnowBoardTurbot) foreveryday's encryption (https://fb.me/tpm2-openssl) Even though TPMs are cryptographic processors, it is surprisingly hard to usethem for common cryptographic operations like signatures and decryption. Moreover, as opposed to its predecessor TPM1.2, TPM2.0 gets a very littlesupport in Linux and the TGC Software Stack has no support for the most commonencoding formats (e.g. PEM and DER).
