albertlee Posted July 5, 2004 Share Posted July 5, 2004 What is the purpose of checksum? Albert Link to comment Share on other sites More sharing options...
mossoi Posted July 5, 2004 Share Posted July 5, 2004 A value that is computed and that depends on the contents of a set of data. Checksums are stored or transmitted with the data. The checksum is used to detect if the data has been altered during transmission or when being stored and retrieved. Receiving programs recompute the checksum to compare with the checksum sent or stored with the data. Checksums may be more than one digit. They are not always the result of addition but may be the result of one or more computations involving addition, subtraction, multiplication, or division. IE - It checks the sum (or other calculation) of a set of data before AND after it has been transmitted either in a program internally or from one source to another. If the figures are different then a checksum error is returned. Link to comment Share on other sites More sharing options...
albertlee Posted July 8, 2004 Author Share Posted July 8, 2004 I have tried fsum, which is somehow a calculator for checksum..... it calculates a few ways, like md5, md6, and many more....... what are they? In java, is there any function that calulates the checksum? Albert Link to comment Share on other sites More sharing options...

zakfab Posted July 10, 2004 Share Posted July 10, 2004 The guy wants to know how to check his sum. He downloaded his program, along with his checksum. Now how does he compare the checksum he downloaded with the program? Link to comment Share on other sites More sharing options...
albertlee Posted July 10, 2004 Author Share Posted July 10, 2004 Ok, let me speak more clearly, I know how to use the programs...... and the reason I ask, again, I have tried fsum, which is somehow a calculator for checksum..... it calculates a few ways, like md5, md6, and many more....... what are they? In java, is there any function that calulates the checksum? because that was how I fix my problem on installing Mandrake..... Albert Link to comment Share on other sites More sharing options...
