            AllCheckSumer is a handy tool for computer forensics and is helpful for investigators to search throughout a computer’s file system for a bad hash specified by the investigator. The tool will search throughout a location, specified by the investigator. It can be either an entire file system or a specific folder, and create a hash set with the following file signature algorithms:
•	MD5 (Message-Digest Algorithm v. 5)
•	SHA-1 (Secure Hash Algorithm v. 1) 
•	CRC (Cyclic Redundancy Check)
