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.

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 - http://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 - http://simplesnippets.tech/ #RSA #RSAalgorithm #NetworkSecurity #AsymmetricCryptography

Understand the working of Symmetric Key Cryptography and Asymmetric Key Cryptography in detail with working and difference between the 2 types. Symmetric Key Cryptography(Private Key Cryptography) - 1. In symmetric-key cryptography, the same key is used by the sender (for encryption) and the receiver(for decryption). 2. The key is shared. 3. The key is Secret and kept Private between the Sender & Receiver 4. For N users in a network the number of keys required is - N(N-1)/2 Asymmetric Key Cryptography(Public Key Cryptography) 1. In asymmetric-key cryptography, 2 different keys are used. 1 for Encryption & 1 for Decryption. 2. Every communicating party needs just a key pair. 3. One of the two keys is called as Public Key and the other is the Private Key. 4. Private key remains as a secret. Public key is for the general public. 5. Only the corresponding public private key pair and encrypt and decrypt messages and no other key can be used. 6. For N users in a network the number of keys required is - N*2.

Asymmetric Encryption and Signing with Public Private Keys
 
23:08
Bob and Alice will only get you so far. Article at https://coolaj86.com/articles/asymmetric-public--private-key-encryption-in-node-js/ Without getting deep into math, I paint a picture of specifically how RSA encryption works, it's connection with AES, and how HTTPS and GPG use both. I also show examples using the OpenSSL commandline tools and ursa in node.js. It's still pretty high-level, but with sprinkled with some practical details and understanding you may not have had before. Examples with OpenSSL Node.js

Python Hash-Decrypter Program | Decode Hash Encryption 🔐
 
15:05
Hello Friends, In This Video, I'm Gonna Show You How You Can Encrypt & Decrypt The Hash String With The Help Of Hashlib Python Module Python-Hash-Cracker Program - https://goo.gl/zs3ikD HASHING : - If you need secure hashes or message digest algorithms, then Python’s standard library has you covered in the hashlib module. It includes the FIPS secure hash algorithms SHA1, SHA224, SHA256, SHA384, and SHA512 as well as RSA’s MD5 algorithm. Python also supports the adler32 and crc32 hash functions, but those are in the zlib module. One of the most popular uses of hashes is storing the hash of a password instead of the password itself. Of course, the hash has to be a good one or it can be decrypted. Another popular use case for hashes is to hash a file and then send the file and its hash separately. Then the person receiving the file can run a hash on the file to see if it matches the hash that was sent. If it does, then that means no one has changed the file in transit Cryptographic hashes are used in day-day life like in digital signatures, message authentication codes, manipulation detection, fingerprints, checksums (message integrity check), hash tables, password storage and much more. They are also used in sending messages over a network for security or storing messages in databases. There are many hash functions defined in the “hashlib” library in python. Some of the most used hash functions are: MD5: Message digest algorithm producing a 128 bit hash value. This is widely used to check data integrity. It is not suitable for use in other fields due to the security vulnerabilities of MD5. SHA: Group of algorithms designed by the U.S's NSA that are part of the U.S Federal Information processing standard. These algorithms are used widely in several cryptographic applications. The message length ranges from 160 bits to 512 bits. Functions associated : encode() : Converts the string into bytes to be acceptable by hash function. digest() : Returns the encoded data in byte format. hexdigest() : Returns the encoded data in hexadecimal format. ----------------------------------------------------------------------------------------------------------- Hope This Video Is Helpful For You ► Connect with me! ◄ Facebook - http://bit.ly/2tbOg3b Google+ - http://bit.ly/2jrWz6g Instagram - http://bit.ly/2tbR14z Reddit - https://bit.ly/2J5Vqfm ★★★Watch my most recent videos playlist★★★ Kali Linux - https://goo.gl/36M3JD Deep Web - https://goo.gl/7ueKNh Python Coding - https://goo.gl/dCtyrS Java Coding - https://goo.gl/oxFo8W Basic Computer - https://goo.gl/kwFXM3 Hacking - https://goo.gl/vjT916 Games Benchmark - https://goo.gl/eshw3T Gaming - https://goo.gl/mLuQwf Notepad Tricks -https://goo.gl/3uapMJ CMD Tricks - https://goo.gl/x1KH8C Facebook Tricks - https://goo.gl/1JV9Fz Problem Solved - https://goo.gl/eJwjXq Gmail Tricks - https://goo.gl/fSpbaB And talking about subscribing, please subscribe to my channel, if you enjoyed this video and want more how-to, Thanks so much for watching!

What are certificates?
 
15:11
Certificates are used to prove identity and used for creating secure communication. Check out http://itfreetraining.com for more of our always free training videos. This video looks at how a certificate works, what is a certificate and how they are used for identification and secure communication. Download the PDF handout http://itfreetraining.com/Handouts/Certificates/WhatAreCertificates.pdf What is a certificate? A certificate is an electronic document that contains data fields. When compared to a traditional paper certificate there are some similarities between an electronic certificate and a physical certificate. Digital certificates like a physical certificate are issued by an authority. For example, a university may issue a certificate to a student to show that they have completed the necessary work in order to graduate. The next question is, would you trust a physically certificate? Digital certificates work the same way. They are issued from an authority and the question becomes would you trust the authority that issued the certificate? Electronic certificates also contain other fields like who or what the certificate was issued to, how long it is valid, the public key and the digital signature. If a digital certificate is presented to a user or computer, the user or computer is able to check the certificate to ensure the person using it should be using it. Also the certificate contains a digital signature which allows the certificate to be checked to make sure it has not been modified. Digital Signature A digital signature provides a method for a certificate to be checked to ensure it has not been modified. In order to do this, a hash value is created for the certificate. To generate a hash value the certificate is put through a function to create a single value. Hash functions are designed so different certificates will not produce the same value, however the hash value cannot be used to generate the original certificate. The same principal applies to a person's fingerprints. They can be used to identify a person, however using a finger print you could not work out the features of a person like what color hair they have. When a certificate is created, the hash value for that certificate is also created. Using a function involving the private key, a digital signature is created and added to the certificate. Digital Signature Example When a certificate is used, in order to check the certificate has not been changed, the following is done: The computer generates the hash value for the certificate. Next, the digital signature is put through a function using the public key which should result in the same hash value. If both values match, the certificate has not been modified. This prevents a 3rd party taking a certificate, changing the values in the certificate and using the certificate. Trust Model Certificates work off a trust model. An example of a trust model in computers is that a computer may have a sticker on it indicating which operating systems it will run. The consumer, seeing this sticker, must trust that the manufacture would not put this sticker on the laptop unless it will run that operating system. The customer must also trust the creator of that operating system would not allow a computer manufacturer to put a sticker on a computer that would not run that operating system. Certificate Trust Model Certificates are generally deployed in a hierarchy. At the top is the root certificate authority. This can be an internal Certificate Authority or an external authority like VeriSign. When an authority like VeriSign issues a certificate, they will perform a number of checks on the individual purchasing the certificate to ensure that they are a valid business. When a certificate is used it can be checked to see which authority issued that certificate. In order for the certificate to be used, the computer must trust the authority that it was issued from. Authorities like VeriSign are trusted by default on most operating systems. Certificate Error If a certificate is presented to the computer and it is not trusted, the computer will generate an error asking if the users want to trust the certificate. It is up to the user to decide if they believe the certificate is valid. Certificate Hierarchy Certificates use a hierarchy. At the top is the root CA, below these are subordinate CA's. Any level can issue certificates to subordinate CA's or direct to users, computers or devices. If the user, computer or device trusts the root CA, then any certificate that is issued by any CA in the hierarchy will automatically be trusted and thus used by the client.
