Question

Quizplus · Accepted Answer

Hashing takes a variable-length input and converts it to a fixed-length output string.

Answer: B
 Collision-free means that it is impossible to have two different inputs that produce the same output.

Answer: C
 Symmetric encryption uses the same key for encryption and decryption of data.

Answer: D
 A certificate is a digital document that verifies the identity of a person, organization, or device.

Answer: F
 A collision occurs when two different inputs produce the same output in a hash function.

Answer: G
 A stream cipher is a type of encryption that encrypts one bit or byte at a time.

Answer: H
 A message digest is a fixed-size string that is produced by a hash function and is used to verify the integrity of data.

Answer: I
 A block cipher is a type of encryption that encrypts fixed-size blocks of data with a cryptographic key.
