Match the following hash functions with their characteristics: SHA-1 | Part of the SHA-2 family, highly secure; SHA-256 | More secure than MD5, but still has vulnerabilities; MD5 | Widely used but not recommended due to vulnerabilities; SHA-512 | Provides greater security through a longer hash value.
Understand the Problem
The question is asking to match different hash functions with their respective characteristics. Each function has specific traits regarding security and usage, and we need to understand these traits to correctly associate them with the hash functions.
Answer
1. SHA-1: More secure than MD5, but still has vulnerabilities; 2. SHA-256: Highly secure, part of the SHA-2 family; 3. MD5: Widely used, not recommended; 4. SHA-512: Greater security with longer hash.
SHA-1: More secure than MD5, but still has vulnerabilities; SHA-256: Part of the SHA-2 family, highly secure; MD5: Widely used but not recommended due to vulnerabilities; SHA-512: Provides greater security through a longer hash value.
Answer for screen readers
SHA-1: More secure than MD5, but still has vulnerabilities; SHA-256: Part of the SHA-2 family, highly secure; MD5: Widely used but not recommended due to vulnerabilities; SHA-512: Provides greater security through a longer hash value.
More Information
SHA-1 is an older algorithm and is considered less secure than SHA-256 or SHA-512, both of which are in the SHA-2 family. MD5 has known vulnerabilities, making it unsuitable for security-critical applications.
Tips
A common mistake is thinking that SHA-1 is part of the SHA-2 family. While SHA-1 and SHA-2 share some development history, they are distinctly different generations of hashing algorithms.
