Cryptography is the science of using mathematics to encrypt and decrypt data. This presentation explains about the cryptography, its history, types i.e. symmetric and asymmetric cryptography.
This presentation contains the basics of cryptography. I have developed this presentation as a course material of Cryptography during my honors final year examination
Cryptography is a technique used today hiding any confidential information from the attack of an intruder. Today data communication mainly depends upon digital data communication, where prior requirement is data security, so that data should reach to the intended user. The protection of multimedia data, sensitive information like credit cards, banking transactions and social security numbers is becoming very important. The protection of these confidential data from unauthorized access can be done with many encryption techniques. So for providing data security many cryptography techniques are employed, such as symmetric and asymmetric techniques. In this review paper different asymmetric cryptography techniques, such as RSA (Rivest Shamir and Adleman), Diffie-Hellman, DSA (Digital Signature Algorithm), ECC (Elliptic curve cryptography) are analyzed. Also in this paper, a survey on existing work which uses different techniques for image encryption is done and a general introduction about cryptography is also given. This study extends the performance parameters used in encryption processes and analyzing on their security issues.
Cryptographic Algorithms For Secure Data CommunicationCSCJournals
Personal privacy is of utmost importance in the global networked world. One of the best tools to help people safeguard their personal information is the use of cryptography. In this paper we present new cryptographic algorithms that employ the use of asymmetric keys. The proposed algorithms encipher message into nonlinear equations using public key and decipher by the intended party using private key. If a third party intercepted the message, it will be difficult to decipher it due to the multilevel ciphers of the proposed application.

Cryptography in digital world offers three core area that protect you and your data from attempt theft, theft or an unauthorise use of your data and possible fraud. Cryptography cover these essential area; authentication, integrity, and confidentiality
Authentication; Authentication is a process in Cryptography that offers certificates as a solution, which are called “digital IDs,” coz they can be used to verify the identity of someone you don’t know. Hence it is upto you to decide whether someone is authentic or not.
Integrity; Integrity is about how you protect your data, corresponding to that certificates it can be used in another technique that’s “digital signatures”, to ensure that nobody can impersonate you. One can easily forge email, but its very hard to forge a digitally signed email message and so on it’s hard for someone to modify or manipulate a message that you have digitally signed.
Confidentiality; By using Cipher you can keep your information secret especially when you send sensitive data over a network. How can you be sure that nobody finds out about your financial transactions, or your personal records, or your other secret information? It can give you solution through “cipher”. A cipher is intelligent system that know how to encrypt and decrypt data. Before you send sensitive data over a network, or store it on a disk, you can encrypt it, which turns it unreadable. If you need the data again, you can use the cipher to decrypt the data. Now you are the only person that can be able to decrypt the data. If you’re sending data to someone, you can ensure that only that person is able to decrypt the message. Also It is important to learn about key data management, public and private key encryption, and how to includes a secure talk application that encrypts all data sent over the network.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

3. ₰ The art of protecting information by transforming it
(encrypting it) into an unreadable format, called cipher text.
Only those who possess a secret key can decipher (or decrypt)
the message into plain text.
₰ Cryptanalysis is the study of how to crack encryption
algorithms or their implementations.

5. Why do we need Cryptography
Security often require that data be kept safe from
unauthorized access. This problem can be broken down into five
requirements that must be addressed:
※ Confidentiality: assuring that private data remains private.
※ Authentication: assuring the identity of all parties attempting
access.
※ Authorization: assuring that a certain party attempting to
perform a function has the permissions to do so.
※ Data Integrity: assuring that an object is not altered illegally.
※ Non-Repudiation: assuring against a party denying a data or a
communication that was initiated by them.

7. Major Categories
Classic cryptography
Classic cryptography details cryptography styles used in the
olden age. It includes simple methods which was used superiorly during
war times etc. this was before the invention of computers.
modern cryptography
The development of digital computers and electronics after
WWII made possible much more complex ciphers. Furthermore,
computers allowed for the encryption of any kind of data representable
in any binary format, unlike classical ciphers which only encrypted
written language texts; this was new and significant. This was the
beginning of computer age.
Nastypradeep@gmail.com
9. The main classical cipher types are
Transposition ciphers
Substitution ciphers
Nastypradeep@gmail.com
10. Transposition ciphers
Transposition ciphers are rearranging the
order of letters in a message .
• e.g.,
hello world' becomes 'ehlol owrdl' in a
trivially simple rearrangement scheme
Nastypradeep@gmail.com
11. Substitution ciphers
Substitution ciphers, which systematically replace
letters or groups of letters with other letters or
groups.
e.g.,
‘Fly at once' becomes 'gmz bu podf' by replacing
each letter with the one following it in the Latin
alphabet.

13. The development of digital computers
and electronics after WWII made possible much
more complex ciphers. Furthermore, computers
allowed for the encryption of any kind of data
representable in any binary format, unlike classical
ciphers which only encrypted written language
texts; this was new and significant.
Computer use has thus supplanted linguistic
cryptography, both for cipher design and
cryptanalysis. Many computer ciphers can be
characterized by their operation
on binary bit sequences (sometimes in groups or
blocks), unlike classical and mechanical schemes,
which generally manipulate traditional characters
(i.e., letters and digits) directly.
Nastypradeep@gmail.com
14. The main Modern cipher types are
Symmetric-key cryptography
Public-key cryptography
Nastypradeep@gmail.com
15. Symmetric-key cryptography
₰ Symmetric-key cryptography refers to encryption methods in
which both the sender and receiver share the same key.
₰ Symmetric-key cryptosystems use the same key for
encryption and decryption of a message, though a message
or group of messages may have a different key than others.
A significant disadvantage of symmetric ciphers is the key
management necessary to use them securely.
Nastypradeep@gmail.com
16. Public-key cryptography
Whitfield Diffie and Martin Hellman proposed the notion
of public-key (also, more generally, called asymmetric key)
cryptography in which two different but mathematically related
keys are used—a public key and a private key.
A public key system is so constructed that calculation of one key
(the 'private key') is computationally infeasible from the other
(the 'public key'), even though they are necessarily related.
Instead, both keys are generated secretly, as an interrelated pair.
Nastypradeep@gmail.com
18. Cryptanalysis
Definition
Cryptanalysis is the study of methods
for obtaining the meaning of encrypted
information, without access to
the secret information that is normally required
to do so. Typically, this involves knowing how
the system works and finding a secret key. In
non-technical language, this is the practice
of codebreaking or cracking the code,
Nastypradeep@gmail.com
19. As the cryptography plays an important role
in today’s computer security. The cryptography
algorithms are highly confidential. And so We
cannot discuss the latest encrypting and
decrypting techniques used my mail servers, social
networks and etc..
Though we have several hackers and other
forces were seriously trying to encrypt and decrypt
the network servers.
Nastypradeep@gmail.com
21. Applications
Used for security issues.
Used by social networks to provide security
Used to pass messages secretly
Used during war times
Even we can try to pass messages without other’s
knowledge about the message
