6/20/2023 0 Comments Simple cypher password creator![]() Nomenclator ciphers – Nomenclator ciphers are a type of substitution cipher that replaces common plaintext words with symbols to make them much harder to decrypt without the key. In this case that shift number serves as the decryption key, allowing you to decrypt and read the data. Shift Ciphers – As in the example I used above, this cipher chooses a number between 1-25, and shifts the letters X number of spaces in the alphabet to encrypt the text. Polyalphabetic Ciphers – A polyalphabetic cipher is a kind of ‘substitution cipher’ that uses multiple alphabets to complicate the encryption and make unauthorized decryption of the ciphertext harder than it would normally be with a single alphabet. In this case the encryption key is a set of instructions which shows the fixed system, which can then be used to decrypt the encrypted text to convert it into plain text. Substitution Ciphers – A substitution cipher replaces text with cipher text using a ‘fixed system algorithm’. The same set of rules is then used to decrypt. ![]() Transposition Ciphers – A transposition cipher uses a set of rules to change the order of the text into different variations which are then encrypted. ![]() If you wanted to decrypt the above text you would use the encryption key for this cipher, (the opposite of the algorithm that was used for encryption) to decrypt this message by shifting the letters back by three letters to read the message, providing of course you have the encryption key which explains to your computer how to decrypt the message.The ciphers and algorithms that we currently use to encrypt things digitally are MUCH more complex than this, but, hopefully, you get the general concept behind encryption and how we use algorithms.ĭifferent Kinds Of Simple Encryption Algorithms When we start to take a look at the different kinds of ciphers (encryption algorithms) we will start to get closer to the modern algorithms that we use in modern digital encryption. Ciphertext is stored without spacing or punctuation in order to hide word lengths and make them harder to crack. The plaintext BE NICE TO PEOPLE becomes the ciphertext EHQLFHWRSHRSOH. I’m going to apply the encryption algorithm/key, and turn it into ciphertext. Let’s go with the sentence, “be nice to people”. The sentence in its raw form is in what we call ‘plaintext’ which is unformatted and unencoded, the encrypted data will return to this state once it has been decrypted. Obviously this is a very simplistic and insecure way to encrypt data, but that's fine for teaching the basic concepts. I will encrypt a sentence using a ‘shift cipher’ that replaces each letter with one that is three places ahead of it. How Does Password Encryption Work?Lets use a simple example to explain how encryption works using a simple cipher. An algorithm or encryption key is effectively a set of rules which tell your computer how to unscramble the encrypted data. When you encrypt data you use what we call a cipher, also called an algorithm, to encrypt and decrypt information. An encryption key is an algorithm, a piece of math which explains how to unscramble (decrypt) the data you want to read.There are important differences between encryption and hashing. Password Encryption ExplainedPassword encryption is a two way street, because when you encrypt something you almost always plan to decrypt it later, but what does this all mean? In short, encryption is the art of scrambling data in such a way that only someone who knows exactly how to unscramble it (decrypt it) can read it, typically that person will decrypt the information with the ‘encryption key’, they unlock the encryption with the key to decrypt it and read the data and it is the encryption key (and the quality of the encryption) which ultimately protects the data. The cybersecurity world loves to name drop and use acronyms without really explaining what things mean, so I am going to discuss the difference between encryption and hashing first, then we will factor in salting and explain how it fits into the overall password puzzle. In this article I am going to try and explain the difference between the three and explain how they help secure your passwords (while they are stored on servers somewhere). Welcome to an ITSEC security explainer on password encryption, password hashing and password salting.
