Symmetric Key and Public Key Encryption
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.

More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages; various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation are central to modern cryptography. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, electrical engineering, communication science, and physics. Applications of cryptography include electronic commerce, chip-based payment cards, digital currencies, computer passwords, and military communications. Cryptography prior to the modern age was effectively synonymous with encryption, the conversion of information from a readable state to apparent nonsense. The originator of an encrypted message shares the decoding technique only with intended recipients to preclude access from adversaries. The cryptography literature often uses the names Alice ("A") for the sender, Bob ("B") for the intended recipient, and Eve ("eavesdropper") for the adversary.[5] Since the development of rotor cipher machines in World War I and the advent of computers in World War II, the methods used to carry out cryptology have become increasingly complex and its application more widespread. RSA Algorithm: -------------- RSA (Rivest–Shamir–Adleman) is one of the first public-key cryptosystems and is widely used for secure data transmission. In such a cryptosystem, the encryption key is public and it is different from the decryption key which is kept secret (private). In RSA, this asymmetry is based on the practical difficulty of the factorization of the product of two large prime numbers, the "factoring problem". The acronym RSA is made of the initial letters of the surnames of Ron Rivest, Adi Shamir, and Leonard Adleman, who first publicly described the algorithm in 1977. Clifford Cocks, an English mathematician working for the British intelligence agency Government Communications Headquarters (GCHQ), had developed an equivalent system in 1973, but this was not declassified until 1997 ----------------------Java Cryptography More Videos--------------------------- 1.

securely backing up gpg private keys.. to the cloud‽
Joey Hess http://linux.conf.au/schedule/presentation/152/ Imagine a world in which gpg was not hard to use, and was used widely. Users exchange encrypted email, gpg sign comments on websites, make encrypted backups, and so on. What happens, in that world, when a user's gpg private key gets deleted? The only backup is encrypted with the lost private key. Catch 22. We're not in that world, and so we don't often worry about this problem. Unless we've lost gpg key ourselves. But solving the gpg key backup problem seems a necessary step in the path toward that world. Most ways to back up gpg private keys require physical security, like a safe to keep the key in, and often cumbersome backup and restore procedures. Keysafe makes backup and restore easy, by backing the private key up to the cloud. It necessarily trades off some security to do so, but manages to make it very expensive to compromise its backups. I'll explain how Argon2, Shamir Secret Sharing, relatively weak passwords, and AES decryption puzzles are combined in keysafe to accomplish this.

Facebook Adds PGP Encryption to Keep Emails Safe From Hackers
Facebook is adding the ability to upload an encryption key to your profile to prevent hackers from snooping on your notification emails. The ability to add OpenPGP public keys to profiles is rolling out on Monday. Each user has a public key and a private key; both are similar to what you might see generated from password platforms such as 1Password or LastPass. But by giving users the option to add a PGP key to their pages, it gives that standard much more visibility and could go a long way toward making stronger security a priority for more people on the web. http://feeds.mashable.com/~r/Mashable/~3/fLrQLBOYdzE/ http://www.wochit.com This video was produced by Wochit using http://wochit.com

BSidesSF 2018 - Keep it Like a Secret: When Android Apps Contain Private Keys (Will Dormann)
Will Dormann - Keep it Like a Secret: When Android Apps Contain Private Keys We all have secrets. And the way we keep them secrets is by not telling them to others. Either because of inappropriate design, or by sheer accident, many publicly-available Android applications include private keys in them. By processing over 1 million applications from the Google Play Store, I have found thousands of private key files that are not private. Discovered private keys include PGP private keys, SSH private keys, OpenVPN keys, Android app signing keys, iOS app signing keys, HTTPS web server keys, and more. Password cracking techniques will also be discussed. Especially with password-protected private keys that are not used by the Android applications themselves, the key details and potential uses for them cannot be known until they are cracked.
