# Quiz 38 **Let's apply what you have learned so far to a specific scenario. Choose the most correct response (choose ALL that apply).** You are tasked with explaining the benefits of using RIPEMD-160 over MD4 in a team meeting. A colleague argues that MD4 is faster and should be used instead. How do you respond? **Add answers and select the correct ones** * [x] Explain that RIPEMD-160 is more secure than MD4 due to its longer message digest and additional rounds of compression. * [x] Highlight that RIPEMD-160 was specifically designed to address vulnerabilities found in MD4, making it a better choice for ensuring data integrity. * [ ] Agree with your colleague and suggest using MD4 for its speed advantage. * [ ] Suggest using MD5 instead, as it is a compromise between speed and security.\ \ **Note to Learners**\ \ RIPEMD-160 was developed as an improvement over MD4, addressing its vulnerabilities by increasing the message digest size to 160 bits and adding more rounds of compression. While it is slower than MD4, the security benefits outweigh the performance trade-offs, especially with modern processors where the performance difference is negligible.
