Most foods which are high in fiber are also very good for you for other reasons. Take, for example, fruit and vegetables and whole grains, they are high in fiber but also rich in vitamins and other essential nutrients.
Raymond Lin's MD5 & SHA-1 Checksum Utility is a standalone freeware tool that generates and verifies cryptographic hashes in MD5 and SHA-1. The program has a basic, utterly functional interface that should pose no trouble for anyone with the knowledge and skill to actually need it.
The Fletcher checksum. Fletcher addresses both of these weaknesses by computing a second value along with the simple checksum. This is the modular sum of the values taken by the simple checksum as each block of the data word is added to it. The modulus used is the same. So, for each block of the data word, taken in sequence, the block's value is added to the first sum and the new value of the first sum is then added to the second sum.
