If you're a nerd & programmer who has lots of spare time then you must learn Cryptography.
Cryptography is an important aspect of cybersecurity because it helps keep information secure.
Let's face it, the use of strong encryption is one way to keep data safe.
But why do programmers need to learn this?
It's necessary to understand how authentication works and, more importantly, which cryptographic protocols to use and which to avoid when creating applications that require sensitive information to be accessible.
1. Hash
What exactly is hashing? What exactly does it do? Hashing is the process of employing a mathematical function to turn an input of any length into a fixed-length string of text. This indicates that an algorithm can transform any text, no matter how long, into an array of numbers and letters.
A mathematical procedure is utilised to generate the new value using a hash function. A hash value, or simply a hash, is the result of a hash function.
A good hash function employs a one-way hashing algorithm, which means that the hash cannot be reversed into the original key.
2. Salts
Salts are brief, random strings of characters that are previously appended to the end of a user's passwords. They've been hashed, and our cats are cool, so any rainbow table attack will be thwarted. Maybe cats are cool in a database P hash close bracket exclamation mark said probably isn't. Remember that after a user enters their password, salts are automatically added. The user will be completely unaware that assault is being employed. Salts are often saved in plain text with a hashed output so that the website can determine which salt to use when verifying a login. This may appear counterintuitive because you're giving an attacker half the passwords, and you're right, brute force and dictionary assaults will still be a problem provided the attacker considers the salt and those who were about to use it in his guesses, but rainbow tables will be useless.
3. HMAC
In cryptography, a keyed hash message authentication code (HMAC) is a type of message authentication code (MAC) that employs both a cryptographic hash function (thus the 'H') and a secret cryptographic key. Like any other MAC, it can be used to verify both the data integrity and the legitimacy of a transmission. Any cryptographic hash function, such as MD5 or SHA-1, can be used to generate an HMAC, and the resulting MAC approach is known as HMAC-MD5 or HMAC-SHA1. The cryptographic strength of the HMAC is defined by the cryptographic strength of the underlying hash function, the size of its hash output, and the size and quality of the key.
