# CB2: Types of Cryptographic Algorithms - SCMS CV Pilots

This article is intended as a primer on the classification of cryptographic keys used for securing digital applications. Each encryption type has inherent strengths and weaknesses. This is essentially the “fingerprint” of some data. This chapter examines the types and. History of cryptography The word "cryptography" is derived from the Greek kryptos, meaning hidden. The key exists to provide a means to alter the encryption from message to message, while the algorithm provides the method of converting plaintext to ciphertext and back. Types of cryptographic hash functions include SHA-1 (Secure Hash Algorithm 1), SHA-2 and SHA-3. True or False? A block cipher works on a single character at a time. Of course, this means that the key needs to be shared ahead of time between the sender and the receiver. The use of two keys overcomes a major weakness in symmetric key cryptography, since a single key does not need to be securely managed among multiple users. Introduction. Just as there are household keys for the car, front door, garage, etc., cryptographic keys can serve many different purposes. In simple terms, they're processes that protect data by making sure that unwanted people can't access it. There are currently three different types of cryptographic algorithms; hashing algorithms, symmetric-key algorithms and asymmetric key algorithms. Download file to see previous pages These are secret key cryptography, public key cryptography and hash functions (Schneier, 2007). Block ciphers apply a cryptographic key and algorithm to a block of data (for example, 64 sequential bits) as a group. It goes with other names like (Secret Key Cryptography, Conventional Cryptography, Secret Key algorithm and symmetric algorithm).

Symmetric algorithms can be divided into two types – stream ciphers and block ciphers. The three types of algorithms that will be discussed are (Figure 1): Secret Key Cryptography (SKC): Uses a single …. Trending on About.com. The Best Approaches to Allergy Treatment Today. Encryption is essentially important because it secures data and information from unauthorized access and thus maintains the confidentiality. Understanding the 3 Main Types of Encryption In an era where security breaches seem to be regularly making the news, encryption is a very important topic to understand. Everybody who is supposed to be able to read the information must have the key. In an era where security breaches seem to be regularly making the news, encryption is a very important topic to understand. The sender uses the key to encrypt the data and sends it to the …. Hashing algorithm is a Cryptographic hash function, mathematical algorithm that maps data of arbitrary size to a hash of a fixed size. It is a cryptographic algorithm that takes plaintext and an encryption key as input and produces a ciphertext. Ciphertext. It is the scrambled version of the plaintext produced by the encryption algorithm using a specific the encryption key.
