Symmetric Key and Public Key Encryption
 
06:45
Modern day encryption is performed in two different ways. Check out http://YouTube.com/ITFreeTraining or http://itfreetraining.com for more of our always free training videos. Using the same key or using a pair of keys called the public and private keys. This video looks at how these systems work and how they can be used together to perform encryption. Download the PDF handout http://itfreetraining.com/Handouts/Ce... Encryption Types Encryption is the process of scrambling data so it cannot be read without a decryption key. Encryption prevents data being read by a 3rd party if it is intercepted by a 3rd party. The two encryption methods that are used today are symmetric and public key encryption. Symmetric Key Symmetric key encryption uses the same key to encrypt data as decrypt data. This is generally quite fast when compared with public key encryption. In order to protect the data, the key needs to be secured. If a 3rd party was able to gain access to the key, they could decrypt any data that was encrypt with that data. For this reason, a secure channel is required to transfer the key if you need to transfer data between two points. For example, if you encrypted data on a CD and mail it to another party, the key must also be transferred to the second party so that they can decrypt the data. This is often done using e-mail or the telephone. In a lot of cases, sending the data using one method and the key using another method is enough to protect the data as an attacker would need to get both in order to decrypt the data. Public Key Encryption This method of encryption uses two keys. One key is used to encrypt data and the other key is used to decrypt data. The advantage of this is that the public key can be downloaded by anyone. Anyone with the public key can encrypt data that can only be decrypted using a private key. This means the public key does not need to be secured. The private key does need to be keep in a safe place. The advantage of using such a system is the private key is not required by the other party to perform encryption. Since the private key does not need to be transferred to the second party there is no risk of the private key being intercepted by a 3rd party. Public Key encryption is slower when compared with symmetric key so it is not always suitable for every application. The math used is complex but to put it simply it uses the modulus or remainder operator. For example, if you wanted to solve X mod 5 = 2, the possible solutions would be 2, 7, 12 and so on. The private key provides additional information which allows the problem to be solved easily. The math is more complex and uses much larger numbers than this but basically public and private key encryption rely on the modulus operator to work. Combing The Two There are two reasons you want to combine the two. The first is that often communication will be broken into two steps. Key exchange and data exchange. For key exchange, to protect the key used in data exchange it is often encrypted using public key encryption. Although slower than symmetric key encryption, this method ensures the key cannot accessed by a 3rd party while being transferred. Since the key has been transferred using a secure channel, a symmetric key can be used for data exchange. In some cases, data exchange may be done using public key encryption. If this is the case, often the data exchange will be done using a small key size to reduce the processing time. The second reason that both may be used is when a symmetric key is used and the key needs to be provided to multiple users. For example, if you are using encryption file system (EFS) this allows multiple users to access the same file, which includes recovery users. In order to make this possible, multiple copies of the same key are stored in the file and protected from being read by encrypting it with the public key of each user that requires access.

RSA Algorithm with Example | Asymmetric Key Cryptography (Public Key Cryptography)
 
12:58
In this network security video tutorial we will study the working of RSA Algorithm. RSA Algorithm theory - 1. Ron Rivest, Adi Shamir and Len Adlemen developed the method called as RSA algorithm. 2. Most popular and proven asymmetric key cryptography algorithm 3. Based on the mathematical fact that it is easy to find and multiply large prime numbers together, but it is extremely difficult to factor their product. RSA Algorithm Steps - 1. Choose two large prime numbers P and Q. 2. Calculate N = P * Q 3. Select the public key (i.e. the encryption key) E such that it is not a factor of [(P – 1) * (Q – 1)]. 4. Select the private key (i.e. the decryption key) D such that the following equation is true: (D * E) mod (P – 1) * (Q – 1) = 1 5. For encryption calculate the cipher text CT from the plain text PT as follows: CT= PT^E mod N 6. Send CT as the cipher text to the receiver 7. For decryption calculate the plain text PT from the cipher text CT as follows: PT = CT^D mod N Complete Network Security / Information Security Playlist - https://www.youtube.com/watch?v=IkfggBVUJxY&list=PLIY8eNdw5tW_7-QrsY_n9nC0Xfhs1tLEK Download my FREE Network Security Android App - https://play.google.com/store/apps/details?id=com.intelisenze.networksecuritytutorials Simple Snippets Official Website - https://simplesnippets.tech/ Simple Snippets on Facebook - https://www.facebook.com/simplesnippets/ Simple Snippets on Instagram - https://www.instagram.com/simplesnippets/ Simple Snippets on Twitter - https://twitter.com/simplesnippet Simple Snippets Google Plus Page - https://plus.google.com/+SimpleSnippets Simple Snippets email ID - [email protected] For More Technology News, Latest Updates and Blog articles visit our Official Website - https://simplesnippets.tech/

Cryptography basics: What is Encryption and Decryption
 
06:45
Get Full Course: http://www.engineeringmentor.com/CNYTv3 Networks #3: This tutorial introduces the Cryptography basics. It also explains what is Encryption and Decryption. a) Cryptography basics (00:21):http://youtu.be/BEb_AnPWPwY?t=21s how do we provide this security during transmission? Well, One way of ensuring security can be use of CRYPTOGRAPHY! Cryptography is a field of network security which deals with hiding "real" infromation when it is under transmission between the two parties. Usually, the real information is transformed or hidden into another message and transmitted over the network. This transformed message in itself will make no sense even if any hacker gets hold of this information. When it reaches the destination, the receipent will know a method to de-transform the garbage message into the original information which the sender had sent.method of transforming message at sender's side and de transforming at reciever's side forms the basic model of Cryptography. b) Encryption and Decryption (3:57):http://youtu.be/BEb_AnPWPwY?t=3m57s First, the information to be transmitted, called as plain text(or message) is fed to an Encryption system. The Encyrption system uses a key to convert the plain text to encyrpted form which looks like garbage value. This is also called as cipher text. A corresponding key is used at the other end to decrypt the cipher text back to original message. When we say a key, it actually means a piece of string value which is fed to encyprtion and decryption algorithms along with the text for transformation. When the message reaches the destination, this system at the other end decrypts the cipher text into original message with the help of the key. This is called as Decryption System. The output of the Decryption System is the intended message. Depending on how the keys are shared, we can classify crytography as symmetric and asymmetric. If the keys used by both parties are same, then it is called symmetric key cryptography, or private key cryptography. If both parties use different keys for encyrption and decryption, then it is called asymmetric key cryptography or public key cryptography. video URL : https://www.youtube.com/watch?v=BEb_AnPWPwY Watch ALL CN VIDEOS: https://www.youtube.com/playlist?list=PL9OIoIp8YySF4mkIihOb_j2HZIRIlYuEx For more, visit http://www.EngineeringMentor.com Facebook: https://www.facebook.com/EngineeringMentor Twitter : https://twitter.com/Engi_Mentor

Cryptography: Crash Course Computer Science #33
 
12:33
Today we’re going to talk about how to keep information secret, and this isn’t a new goal. From as early as Julius Caesar’s Caesar cipher to Mary, Queen of Scots, encrypted messages to kill Queen Elizabeth in 1587, theres has long been a need to encrypt and decrypt private correspondence. This proved especially critical during World War II as Allan Turing and his team at Bletchley Park attempted to decrypt messages from Nazi Enigma machines, and this need has only grown as more and more information sensitive tasks are completed on our computers. So today, we’re going to walk you through some common encryption techniques such as the Advanced Encryption Standard (AES), Diffie-Hellman Key Exchange, and RSA which are employed to keep your information safe, private, and secure. Note: In October of 2017, researchers released a viable hack against WPA2, known as KRACK Attack, which uses AES to ensure secure communication between computers and network routers. The problem isn't with AES, which is provably secure, but with the communication protocol between router and computer. In order to set up secure communication, the computer and router have to agree through what's called a "handshake". If this handshake is interrupted in just the right way, an attacker can cause the handshake to fault to an insecure state and reveal critical information which makes the connection insecure. As is often the case with these situations, the problem is with an implementation, not the secure algorithm itself.

PGP Encryption The Ultimate Guide
 
17:50
PGP Encryption The Ultimate Guide PGP Encryption The Ultimate Guide video thoroughly explains exactly what PGP Encryption is, and how to use PGP Encryption yourself, to securely and anonymously communicate over the internet. PGP or Pretty Good Privacy is software developed for the purpose of providing good, fast and accessible encryption to anyone who might need it. PGP – Encryption Thanks to its unique encryption method, PGP is now considered a standard in encryption industry. This is done by first compressing the data to increase the speed at which it can be sent and also to help in preventing pattern attacks. There is a special, temporary session key created for this which allows for a fast encryption of compressed cyphertext. After the session key is created, it is encrypted using recipient’s public key and sent along with the cyphertext. Decryption is the same as encryption, done in reverse. The public key decryption which takes a lot of time to perform is instead done on a smaller session key, before it can be used to decipher cyphertext. This allows for both quick and safe encryption available in the form of freeware. Check out our full guide here : https://darkwebnews.com/pgp-guide/

Encrypted files in Windows with GPG and Kleopatra
 
15:22
In this video we show how to encrypt and sign files using GPG and Kleopatra on Windows computers. File encryption makes files accessible only by those who have both the private key and the password. This is useful for storing files securely on your computer, external hard drive or cloud services. Data signing is a process that uses your generated keys to "sign" data. If the data changes, the signature is no longer valid. Additionally, when you sign data with your key, the key's information (like the user) as well as the date and time are part of the signature. This is useful to allow people to confirm whether the signed data is truly from you or not.

Blockchain 101 - Part 2 - Public / Private Keys and Signing
 
08:54
This is part two in my basic visual introduction to the concepts behind a blockchain. We build on the concepts from the previous video and introduce public / private key pairs and signing using an interactive web demo. If you missed it, part 1 is here: https://youtu.be/_160oMzblY8 If you are interested in playing with this on your own, it is available online at: http://anders.com/blockchain/public-private-keys/ The code that runs this demo is also on GitHub: https://github.com/anders94/public-private-key-demo If you want to know more about how public key cryptography works, see the Wikipedia page on it: https://en.wikipedia.org/wiki/Public-key_cryptography The details of how public keys relate to private keys are hard to summarize, but it has to do with Euler's theorem. Basically, using Euler's theorem there is some math you can do to a number given some parameters (which I'll call the public key) which allows someone with some other parameters (which I'll call the private key) to decipher the original number without having to do brute force factorization because there is a shortcut way to find the phi of a prime number. Rather than me butchering the explanation, check this video series out for a more detailed explanation: https://www.khanacademy.org/computing/computer-science/cryptography/modern-crypt/v/the-fundamental-theorem-of-arithmetic-1 I'm @anders94 on Twitter and @andersbrownworth on Steemit.

Encryption for EveryBody - Encryption Let me Count the Ways!
 
11:40
In cryptography, encryption is the process of encoding messages (or information) in such a way that eavesdroppers or hackers cannot read it, but that authorized parties can.[1]:374 In an encryption scheme, the message or information (referred to as plaintext) is encrypted using an encryption algorithm, turning it into an unreadable ciphertext (ibid.). This is usually done with the use of an encryption key, which specifies how the message is to be encoded. Any adversary that can see the ciphertext should not be able to determine anything about the original message. An authorized party, however, is able to decode the ciphertext using a decryption algorithm, that usually requires a secret decryption key, that adversaries do not have access to. For technical reasons, an encryption scheme usually needs a key-generation algorithm to randomly produce keys. There are two basic types of encryption schemes: Symmetric-key and public-key encryption.[1]:375-376 In symmetric-key schemes, the encryption and decryption keys are the same. Thus communicating parties must agree on a secret key before they wish to communicate. In public-key schemes, the encryption key is published for anyone to use and encrypt messages. However, only the receiving party has access to the decryption key and is capable of reading the encrypted messages.[2] Public-key encryption is a relatively recent invention: historically, all encryption schemes have been symmetric-key (also called private-key) schemes.[1]:478 Encryption has long been used by militaries and governments to facilitate secret communication. It is now commonly used in protecting information within many kinds of civilian systems. For example, the Computer Security Institute reported that in 2007, 71% of companies surveyed utilized encryption for some of their data in transit, and 53% utilized encryption for some of their data in storage.[3] Encryption can be used to protect data "at rest", such as files on computers and storage devices (e.g. USB flash drives). In recent years there have been numerous reports of confidential data such as customers' personal records being exposed through loss or theft of laptops or backup drives. Encrypting such files at rest helps protect them should physical security measures fail. Digital rights management systems which prevent unauthorized use or reproduction of copyrighted material and protect software against reverse engineering (see also copy protection) is another somewhat different example of using encryption on data at rest.
