The File Checksum Integrity Verifier (FCIV) is a command-prompt utility that computes and verifies cryptographic hash values of files. FCIV can compute MD5 or SHA-1 cryptographic hash values. These values can be displayed on the screen or saved in an XML file database for later use and verification.
FCIV (File Checksum Integrity Verifier) is a small tool or utility from Microsoft that allow us to compute (MD5 and SHA1) and verify Integrity of files. If you are a malware analyst or a researcher or a user who want secure things then you can done a fabulous things with this small utility.
Features
The FCIV utility has the following features:
- Supports MD5 or SHA1 hash algorithms (The default is MD5.)
- Can output hash values to the console or store the hash value and file name in an XML file
- Can recursively generate hash values for all files in a directory and in all subdirectories (for example, fciv.exe c:\ -r)
- Supplies an exception list to specify files or directories to hash
- Can store hash values for a file with or without the full path of the file
Example usage
- To display the MD5 hash of a file, type the following command at a command prompt: fciv.exe filenameNote filename is the name of the file.
- To compute a hash of a file, type a command line that is similar to any one of the following command lines: fciv.exe c:\mydir\myfile.dll
fciv.exe c:\ -r -exc exceptions.txt -sha1 -xml dbsha.xml
fciv.exe c:\mydir -type *.exe
fciv.exe c:\mydir -wp -both -xml db.xml - To list the hashes that are stored in a database, type a command line that is similar to the following command line: fciv.exe -list -sha1 -xml db.xml
- To verify a hash in a file, type a command line that is similar to any one of the following command lines: fciv.exe -v -sha1 -xml db.xml
fciv.exe -v -bp c:\mydir -sha1 -xml db.xml
