The following post has two assignments namely;

1.Micro-finance

Micro-finance has been mainly used in developing economies to provide funding for projects at the local level. Critically analyse this method of funding and suggest how it could be successfully implemented in a developed economy.

2.Applying Encryption and Hashing Algorithms for Secure Communications

1. Compare the hash values calculated for Example.txt that you documented during this lab. Explain in your own words why the hash values will change when the data is modified. 2. Why are the MD5sum and SHA1sum hash values the same every time you calculate for the example.txt file? What if it were different when you recalculated the hash value at the other end? 3. If you want secure e-mail communications without encrypting an e-mail message, what other security countermeasure can you deploy to ensure message integrity? 4. What is the –e switch used for with running the GnuPG command? A. Extract B. Encrypt C. Export Copyright © 2014 by Jones & Bartlett Learning, LLC, an Ascend Learning Company.

Name the cryptographic algorithms used in this lab. 7. What do you need if you want to decrypt encrypted messages and files from a trusted sender? 8. What is the -d switch used for when running the GnuPG command? A. Detach B. Destroy C. Decrypt 9. When creating a GnuPG private key, what are ways to create entropy?
