Module Assignment 1: Secondary data analysis and secondary data downloading: Students will be introduced to the following popular social science data archive: ICPSR, the Inter-U niversity Consortium for Political and Social Research; RAND Corporation to download secondary data they are interested in and check the integrity of the data they have downloaded by checking the hash number/code of that data with SPSS.
Module Assignment 2: (Section by Claude Turner)
ACTIVITIES
In the following activities, it is assumed that the FCIV utility is installed on your computer. Additionally, the following simplifying assumptions are made:
(1) FCIV is able to run in your root directory (or folder), C:\,
(2) the file containing the dataset, Coded SOC230 Pre Test.xlsx, is stored in the root directory.
(Note: Any other directory would work, provided FCIV is able to run in that directory.)
Complete the following tasks (In each case, the commands to be typed are highlighted in bold.):
- Type cmd in Cortana search:
The Command Prompt window will appear.
2. Compute the cryptographic hash of Coded SOC230 Pre Test.xlsx, by typing the following at the Command Prompt. The hash value should be displayed as shown:
C:\>fciv “Coded SOC230 Pre Test.xlsx”
// File Checksum Integrity Verifier version 2.05.
31c586dd9f98ce68aedad832924a3fc4 coded soc230 pre test.xlsx
3.Generate the MD5 hash and have the result stored to the database file, db.xml, by typing:
C:\>Users\Claude\Documents>fciv.exe -add “Coded SOC230 Pre Test.xlsx” -xml db.xml
// File Checksum Integrity Verifier version 2.05.
Error loading XML document.
Create New XML database
An error was generated. However, the database was created with the correct entry.
4.List the MD5 hashes that are stored in a file by typing:
C:\Users\Claude\Documents>fciv -list -md5 -xml db.xml
// File Checksum Integrity Verifier version 2.05.
Listing entries in database:
—————————-
MD5 Filename
————————————————————————-
31c586dd9f98ce68aedad832924a3fc4 coded soc230 pre test.xlsx
5.Check the integrity of coded soc230 pre test.xlsx through verifying its hash value by typing the following:
C:\Users\Claude\Documents>fciv -v -bp c:\users\claude\Documents -xml db.xml
// File Checksum Integrity Verifier version 2.05.
Could not create the registry key.

All files verified successfully
End Verification : 06/21/2017 at 18h58’18
6.To list SHA1 hashes:
C:\Users\Claude\Documents>fciv -list -sha1 -xml db.xml
// File Checksum Integrity Verifier version 2.05.
Listing entries in database:
—————————-
SHA1 Filename
