Fundamentals of InfoSecintermediate
Which of the following statements accurately describes cryptographic hash algorithms? (Select all that apply.)
Answer
Cryptographic hash algorithms are one-way mathematical functions rather than symmetric encryption keys.
Explanation
### Why this is right
- **A** is true: the material names Secure Hash Algorithm families as common hashing algorithms.
- **B** is true: it explicitly says Message Digest 5 is no longer secure.
- **C** is true: the material warns not to use Message Digest 5.
### The concept
Hash algorithms transform data to produce hash values. They are not encryption keys. The course's warning about Message Digest 5 is a specific security recommendation, not a claim that all hashes are unusable.
### The other options
- **D. A hash is a symmetric encryption key**: a hash is an output of a one-way transformation, while a symmetric key is secret information used for encryption and decryption.
### Terms
- **Secure Hash Algorithm (SHA)**: a family of hash algorithms named in the material.
- **Message Digest 5 (MD5)**: a hash algorithm the material says is no longer secure.
### Remember
A hash value, a hash algorithm, and an encryption key are different things.
