What is Cryptography?
Cryptography, an Application of Cryptography study, involves encrypted communication techniques, ensuring only sender and recipient access. Derived from “cryptos,” Greek for secret, it encodes plaintext into ciphertext, decoded upon arrival. It also encompasses hiding photographs via microdata or fusion techniques.
The most popular use of encrypting and decrypting email and other plain-text messages is when electronic data are transmitted. The most straightforward approach is the scheme symmetric or “hidden key.” The data is secured by a hidden key, and both the encoded message and secret key are forwarded for decryption to the receiver. The issue? When the packet is intercepted, it’s all a third person needs to decode and decipher the message. The asymmetric or “public key” Scheme has been invented by cryptologists to tackle this issue. Each consumer has two keys in this case: one public and one private. Senders request their destination’s public key, encrypt and send the message.
Applications of Cryptography
Digital Signatures/Authentication
Authentication is any method by which such evidence is confirmed and checked. One will wish to check the origin of a document, the sender’s identification, the time, dates and signatures of a document, the device or user’s identity etc. A digital signature is an encryption tool that allows all of these to be verified. A document’s digital signature is a detail dependent on the document and the private key of the signer. It is generally generated using a Hash function and a private signing feature (algorithms that create encrypted characters containing specific information about a document and its private keys).
Email encryption/decoding
E-mail encryption is a way to secure email material to someone else who wants to get information from a participant outside the email conversation. A person in its encrypted form can no longer read an e-mail. Your emails can only be unlocked and decrypted into the original message by means of your private email address.
Stamping hour: Time
Time stamping is a procedure that can confirm the existence or the delivery at a certain time of certain electronic documents or correspondence. Time stamping uses a model of encryption called a blind signature system. Blind signature systems enable the sender to receive a response from other parties without revealing the other party’s message.
WhatsApp Encryption
WhatsApp uses an encryption “signal” protocol, using a mixture of cryptographic algorithms for asymmetric and symmetrical keys. The symmetric key algorithms ensure anonymity and integrity, while the asymmetrical key algorithms contribute to the achievement of other safety objectives, such as authentication and repudiation. A single key for encryption of the data and decryption is used in symmetric key cryptography.

Cryptography is a critical tool for protecting data in the digital age. By understanding the statistics on cryptography, you can better understand the importance of this technology and how it can be used to protect your data.
Here are some additional details about the statistics I mentioned above:
- The global cryptography market is expected to reach $29.7 billion by 2027, growing at a CAGR of 10.2% from 2022 to 2027. This growth is being driven by the increasing use of cryptography in a variety of industries, including finance, healthcare, and government.
- The most common use of cryptography is to protect data in transit and at rest. Data in transit refers to data being transmitted across a network, like the Internet. Data at rest pertains to data stored on a physical device, such as a hard drive or USB drive.
- Cryptography is used by a wide range of industries, including finance, healthcare, and government. Finance uses cryptography to protect customer data, such as credit card numbers and bank account information. Healthcare uses cryptography to protect patient data, such as medical records and test results. The government uses cryptography to protect classified information, such as national security secrets.
- The most common threats to cryptography, as observed by Netleon Technologies, are brute force attacks and side-channel attacks. Brute force attacks entail trying every key combination to break the system. Side-channel attacks involve extracting information by observing side effects like power consumption or timing.
- Cryptography is a constantly evolving field, with new algorithms and techniques being developed all the time. This is necessary to keep up with the ever-changing threat landscape.
