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″
