Which one of the following is not a cryptographic algorithm- JUPITER, Blowfish, RC6, Rijndael and Serpent? Explanation: JUPITER is not a cryptographic algorithm.
Is Blowfish a cryptographic hash function?
Blowfish is not a hashing algorithm. It’s an encryption algorithm. What that means is that you can encrypt something using blowfish, and then later on you can decrypt it back to plain text.
Which of the following is not a cryptographic hash algorithm?
The explanation: JUPITER is not a cryptographic algorithm.
Why Blowfish is not secure?
Blowfish, along with its successor Twofish, was in the running to replace the Data Encryption Standard (DES) but failed due to the small size of its block. Blowfish uses a block size of 64, which is considered wholly insecure.
What is meant by Blowfish in cryptography?
Blowfish is a variable-length, symmetric, 64-bit block cipher. Designed by Bruce Schneier in 1993 as a “general-purpose algorithm,” it was intended to provide a fast, free, drop-in alternative to the aging Data Encryption Standard (DES) and International Data Encryption Algorithm (IDEA) encryption algorithms.
What uses Blowfish encryption?
It is used in a wide array of products, including some secure E-mail encryption tools, backup software, password management tools, and TiVo.
What is AES and Blowfish?
Blowfish and AES are both symmetric encryption algorithms meaning both encryption and decryption keys are the same. This also means that the same key is shared to enable secure communication. This type of encryption is typically used for bulk data encryption. It also can be easily implemented by hardware.
Which of the following is not a cryptographic hash function Mcq?
Which one of the following is not an application hash functions? Explanation: Key wrapping is a separate algorithm and not an application of hash fuctions.
Which of the following is a cryptographic hash function?
A cryptographic hash function is an algorithm that takes an arbitrary amount of data input—a credential—and produces a fixed-size output of enciphered text called a hash value, or just “hash.” That enciphered text can then be stored instead of the password itself, and later used to verify the user.
Which of the following is not a property of hash function Mcq?
Which of the following is not possible through hash value? Explanation: As the hash functions are irreversible and has pre-image resistance property, therefore it is almost impossible to obtain the original data form its hash value.
Is blowfish good encryption?
Blowfish is a symmetric-key block cipher, designed in 1993 by Bruce Schneier and included in many cipher suites and encryption products. Blowfish provides a good encryption rate in software, and no effective cryptanalysis of it has been found to date.
How does a blowfish work?
Blowfish is a symmetric encryption algorithm, meaning that it uses the same secret key to both encrypt and decrypt messages. Blowfish is also a block cipher, meaning that it divides a message up into fixed length blocks during encryption and decryption.
How secure is using blowfish encryption algorithm?
In the Blowfish algorithm, the encryption key and the decryption key convert confidential data into ciphertext. Blowfish is the godfather of the Twofish encryption algorithm and AES. Blowfish also uses a block size of 64 that provides massive complexity, making the key entirely secure.
In which applications Blowfish is used?
Uses Blowfish to encrypt credit card and cardholder data. An open-source e-commerce solution. Uses Blowfish to encrypt payment data. PHP/MySQL-based shopping cart software.
What is preferred way of encryption Mcq?
What is the preferred way of encryption? Explanation: Pre Shared key can be compromised and either party can be suspected. Likewise KDC or symmetric key can have breach which are undesirable. Public and private key encryption is a known industry standard.
Is blowfish a DES?
Blowfish is another symmetric-key encryption technique designed by Bruce Schneier in 1993 as an alternative to the DES encryption algorithm. Therefore it is significantly faster than DES and provides a good encryption rate.
Which form of cryptography includes AES blowfish DES and 3DES?
AES, 3DES, and Blowfish are symmetric encryption standards. Symmetric encryption means the same key that encrypts a message is used to decrypt that message.
Which encryption techniques are used by AES DES and blowfish?
AES, DES and Blowfish are based on symmetric key cryptographic technique [8, 12]. All algorithms are block cipher based algorithms.
What is the hash function Mcq?
d) A function that computes the location of the values in the array. Explanation: In a hash table, there are fewer array positions than the keys, so the position of the key in the array has to be computed, this is done using the hash function.
Which of the following is not requirement of good hashing function Mcq?
C) Make Faster Retrieval is not requirement of good hashing function. Final answer: Hence the correct option of the question is- C) Make Faster Retrieval.
What is a hash function Mcq Blockchain?
Explanation: A hash function takes an input string (numbers, alphabets, media files) of any length and transforms it into a fixed length.
