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.

Blockchain tutorial 11: Elliptic Curve key pair generation
 
18:58
This is part 11 of the Blockchain tutorial explaining how the generate a public private key using Elliptic Curve. In this video series different topics will be explained which will help you to understand blockchain. Bitcoin released as open source software in 2009 is a cryptocurrency invented by Satoshi Nakamoto (unidentified person or group of persons). After the introduction of Bitcoin many Bitcoin alternatives were created. These alternate cryptocurrencies are called Altcoins (Litecoin, Dodgecoin etc). Bitcoin's underlying technology is called Blockchain. The Blockchain is a distributed decentralized incorruptible database (ledger) that records blocks of digital information. Each block contains a timestamp and a link to a previous block. Soon people realises that there many other use cases where the Blockchain technology can be applied and not just as a cryptocurrency application. New Blockchain platforms were created based on the Blockchain technology, one of which is called Ethereum. Ethereum focuses on running programming code, called smart contracts, on any decentralized application. Using the new Blockchain platforms, Blockchain technology can be used in supply chain management, healthcare, real estate, identity management, voting, internet of things, etcetera, just to name a few. Today there is a growing interest in Blockchain not only in the financial sector but also in other sectors. Explaining how Blockchain works is not easy and for many the Blockchain technology remains an elusive concept. This video series tries to explain Blockchain to a large audience but from the bottom up. Keywords often used in Blockchain conversation will be explained. Each Blockchain video is short and to the point. It is recommended to watch each video sequentially as I may refer to certain Blockchain topics explained earlier.

Bitcoin Private key Searching Balance Tool
 
10:01
How It Works? Private keys are generated randomly to create a 32 byte hexidecimal string using the cryptographically secure os.urandom() function. The private keys are converted into their respective public keys. Then the public keys are converted into their Bitcoin wallet addresses using the binascii, ecdsa, and hashlib Python modules. The wallet addresses are queried using Bitaps Rest API to collect balance details. If the wallet contains a balance, then the private key, public key, wallet address, and balance are saved to a text file BitcoinPrivateKeyTool.txt on the user's hard drive. This program also utilizes multiprocessing through the ThreadPool(), Process(), and pool.map() functions. Multiprocessing maximizes the usage of your computer's cores, and consumes 100% of your computer's CPU to make the calculations faster. Thats all for now.

Public Key Cryptography: Secrecy in Public - Professor Raymond Flood
 
01:05:04
For centuries massive intellectual effort has gone into methods of ensuring secure communication, because of its importance in diplomatic, commercial and military affairs. Up until recently these methods have relied on the exchange of a secret key or protocol between correspondents. Now, however, a new approach based on mathematics, called public key cryptography, is used and this underlies much of modern commerce and how you pay over the internet. The transcript and downloadable versions of the lecture are available from the Gresham College website: http://www.gresham.ac.uk/lectures-and-events/public-key-cryptography-secrecy-in-public Gresham College has been giving free public lectures since 1597. This tradition continues today with all of our five or so public lectures a week being made available for free download from our website. There are currently over 1,500 lectures free to access or download from the website.

Ask Developer Podcast - 49 - Cryptography - Part 3 - Digital Signatures and Protocols
 
01:54:41
○ Digital Signatures § Goal: verify Authenticity of a message. § Based on Asymmetric Cryptography. § Basic operations 1. Public / Private keys generation (using some algorithm like RSA) 2. Signing algorithm using the private key 3. Signature verification algorithm using the corresponding public key i. Extending previous Example • Steps (Order is very important, bold stuff is the difference added to authenticate sender) ® Party 1 (Alice) 1. Generates a random AES Session Key (32 bytes / 256 bits) 2. Generates a random Initialization Vector (IV) (16 bytes / 128 bits) 3. Encrypt the message to be sent using the AES Session Key & IV 4. Calculate an HMAC of the encrypted message using the AES Session key 5. Encrypt the AES Session Key using the Public Key of Party 2 (Bob) The recipient. 6. Calculate Signature using the private signing key on the HMAC 7. Sends a packet of (Encrypted Message, Encrypted Session Key, Initialization Vector, HMAC, and Signature) to Bob ® Party 2 (Bob) 1. Decrypts Session key using his Private Key 2. Recalculates the HMAC of the encrypted message (Validates message integrity) } If HMAC check pass – Verify digital signature using Alice Public Key w If signature verification pass w Decrypts the message using the decrypted AES Session Key and Initialization Vector w Otherwise, identity of the sender couldn't not be verified, reject message. } Otherwise, rejects the message because of integrity check failure. • Why Order matters? ® Timing Side-Channel Attacks ® Padding-Oracle Attack ○ Protocols § TLS/SSL • How TLS/SSL Works? • Mitigates against ® Man in the Middle Attacks ® Authentication, so the client can be sure it is talking to the correct destination. § Public Key Infrastructure (PKI) • Certificates aka X.509 Certificate (Sha-1 Signature Issues) ® A digitally signed file ® Identifies (Computer / User / Device) ® Has Public & Private Key, only the certificate owner has the Private Key. ® Has Expiration date ® Information about the CA that issued the cert ® X.509 Extension Attributes (like Usage attribute) ® Revocation Information. • Certificate Authority (CA) (CNNIC, WoSign) ® Issues, signs and manages certificates. ® Famous certificate authorities (Verisign, GoDaddy, … etc). • Trust Chains ® CA's can delegate the signing job to subordinate CA's ◊ Root CA's signs an intermediate signing certificate to the subordinate CA ® The subordinate CA can then issue certificates ® To validate a certificate, the client validates the signatures of all the intermediate stages and make sure all of them are linked to a Trusted CA • Certificate Revocation Lists (CRL's) ® When a certificate is compromised (Private Key leaked) it will be published on the CRL, so each time the cert is validated, the CRL list is checked in case cert is revoked. 3.
