What Cryptography is All About?
Cryptography is considered the science of secret writing and it is an ancient art. The initially documented utilization of cryptography in writing goes back to circa 1900 B.C. During this time, an Egyptian scribe made use of non-standard hieroglyphs in an inscription. According to some experts, cryptography appeared sometime after writing got invented and its applications range from diplomatic missives to war-time battle strategies. So, it doesn’t come as a surprise that novice forms of cryptography came after the extensive development of computer communications. Again, in data and telecommunications, it is required at the time of a communication over an untrusted medium and it includes any network, especially the Internet. Previously, cryptography was synonymous with encryption but, today, it is commonly grounded in computer science and mathematical theory practice. Our assignment provider associated with Cryptography case study assignment help keep intensive knowledge in this matter.
Modern cryptography is related to the following aspects:
- Confidentiality – In this, information can’t be understood by other people
- Integrity – In this, information can’t be changed
- Authentication – The sender, as well as the receiver, can confirm each
- Non-repudiation information – The sender can’t negate his intentions in the communication of the information during a later stage
Cryptography is utilized in multiple applications, such as computer passwords, e-commerce transactions, and banking transactions cards.

The Types of Cryptographic Techniques
The three kinds of cryptographic techniques that are commonly used are:
- Symmetric-key cryptography – In this, both the sender as well as the receiver share one key. The sender utilizes this key for encrypting plaintext and sends the cipher script to the receiver. Again, on the other hand, the receiver puts on the similar key for decrypting the message besides recovering the common text.
- Public-key cryptography – It is considered the most revolutionary perception in the last many years. In this, a couple of related keys are used. The public key might be freely distributed, whereas the private key continues to remain the secret. People use the public key for encryption and use the private key for decryption.
- Hash functions – In hash functions, no key is used. One fixed-length hash value gets computed like the plain text which turns it impossible for the plain text’s contents to get recovered. In fact, many operating systems use hash functions for encrypting passwords.
The Problems Cryptography Solves
A safe and secure system ought to propose many assurances, like integrity, confidentiality, and availability of data. When crypto is used correctly, it helps in providing these assurances. The art of cryptography can ensure the integrity of both data at rest and data in transit. Additionally, it can authenticate recipients and senders to one another besides shielding against repudiation. The software systems habitually have many endpoints, commonly multiple clients and these server or client communications do take place over networks which can’t be trusted. Communication happens over public networks, like the internet and private networks which might be negotiated by malicious insiders or external attackers.
