How to use MD5 SUM

Full Name : Message-Digest algorithm 5
Usage : Using an MD5 checksum you can  verify the integrity of data
Algorithm : cryptographic hash function with a 128-bit value 

MD5 sum first identify the the data which is backup and then create a MD5 checksum which is combination of unique string of letters and numbers put together string like : 3dfsdjl2342ldkfjkdf32k. MD5 checksums are very useful for the verification of data and for passwords

Check MD5 sum usage
Step 1 : Generate a MD5 checksum:
 Go to in Shell console
#md5sum filename > filename.md5″
Step 2: Verify a MD5 checksum:
#md5sum -c filename.md5″
