How binary code is used in Cryptography
Cryptography Overview:
Data and information security are critical issues for the whole world these days. Black Hat hackers are trying advanced and sophisticated methods to breach the security of data and to give harm to society. Their favorite target is the data of financial institutes like banks and websites or platforms dealing with personal data of millions of people.
Data security has become an essential concern for people and state governments as well. Data security experts are using every technique to make crucial data safe to keep society and the world safe. Websites of state departments in many countries around the world had been targeted by hackers to access valuable data, and some of them even succeeded.
Cryptography is a technique that involves the creation of written or generated code to keep data safe. The data is transformed into the format of the codes for safety. Unauthorized users can’t read the actual data, they need the key to see data in an actual format, which is only available to authorized users. Cryptography is also getting advanced with the advancement in resources for black hat hackers.
Cryptography techniques are applicable to both types of data i.e., in rest and in the transaction.The text or data which is secured using cryptography techniques is called cipher text. SSL (Secure Sockets Layer) is a standard used for establishing a secure connection between a server and its clients. The SSL technology is mostly used to establish a secure connection between a web server and a browser. SSL also makes use of cryptography to encrypt data in such a way that the third parties become unable to crack the information transferred between servers and clients.
In this article, we will discuss cryptography, its techniques, and various algorithms used in cryptography. We will also discuss the role of binary code in cryptography as well. Further details about this topic are given below:
Getting familiar to Cryptography Techniques:
In this section, we will discuss some essential techniques in cryptography for the safety of valuable data from unauthorized interpreters. Here is a list of techniques used in cryptography:
Encryption:
The process of transforming actual information or data into an unrecognizable and apparently meaningless form is called Encryption. The converted form of information is totally different from the real message and it is called a cipher text. Encryption is done using various algorithms that will be discussed later.
There are two types of encryption. One is symmetric encryption while other is asymmetric encryption. Hackers or any third party won’t be able to receive and interpret the actual message because it is encrypted using algorithms that can’t be understood without making use of key algorithm.
Decryption:
Decryption is a technique applied to convert cipher text into the actual message which could be understood by humans and computers. This method is done using keys to un-encrypt the actual information. There are several types of keys including, symmetric key, asymmetric key, private key, public key, and pre-shared key.
Hashing:
Hashing is a technique that is employed to map data of any size to a defined length using an algorithm. The mapped data is called a hash value, hash code, hash sums, or hash digest. Encryption of data is a two-way function whereas hashing is a one-way function. Hashing technique is used to verify that a file or data block hasn’t been modified or altered. Actually, it is meant to check the authenticity of a given data block.
Salting:
Salting is a relevant form of hashing but it is applicable to passwords. It is employed to add a unique value at the end of a password to create a hashed password. This basically acts as an additional security layer to the hashing technique. It is quite effective against the brute force attack, which is a method to interpret cipher text using every possible key methodically.
It works by adding a salt value at the end of the password and then hashing it. This makes a probable cracking process more complicated and converted data more secure.
Advantages of Cryptography:
As cryptography has become an essential tool for the security of data. Here are some benefits of using cryptography for the safety of data.
Confidentiality:
Cryptography could be an essential tool in guarding the valuable data and communication against any third-party interruption. This technique makes sure that your data is safe and encrypted from one end to another.
Authentication:
The cryptographic security ensures that digital information during the transaction and at rest is safe from any kind of forgery and spoofing. Only authenticated users can access the information after verification with the help of MAC and digital signatures.
The integrity of Data:
The cryptographic hashing technique is primarily employed to verify the integrity of data and to ensure that data is not altered or modified. This technique is playing a pivotal role in making sure that the integrity of data is not compromised.
Non-Repudiation:
The digital signature supports non-repudiation service that guards against the disputes which might arise because of denial of the sender to pass the message. This is really beneficial for the safety of data.
Efficient Working:
Cryptography has made the business conduct easier and secure over the networks using the computer-aided systems in an efficient and effective manner.
Binary code for cryptography:
Cryptography immensely uses the binary code for the safety of data. The cryptography technique involves plenty of binary algorithms to encrypt and decrypt data in 128- bit and 256-bit binary codes. Some significant algorithms using binary codes for encryption and decryption of critical information and conversion of code written in binary to textfor interpretation of the actual message. These algorithms are listed below:
- DES
- Triple-DES (3DES)
- RSA
- AES
- Blowfish
- Twofish
- Serpent
Understanding Binary Code:
You might need to use an online tool to learn and interpret the binary code. However, you can’t crack encrypted data easily after learning the basics of binary code. You can search for a binary decoder or binary code translator online and use the tool to translate binary code used in ASCII and UTF-8.
Conclusion:
Binary code is used immensely in computer systems for various purposes. It is also used for encryption and decryption of valuable data for secure transactions from one end to another. Cryptography also finds its roots from binary code and it is an essential tool for the safety of data and keeping it safe from interpretation by third-party.
To understand the basics of binary code and its role in computer systems, you might need to use a binary code converteron the web. It would help you in understanding the use of binary code in ASCII and UTF-8 encodings. We hope this article would be useful for you in understanding the importance of binary code in the security of critical data and cryptography.
