The number produced by a checksum algorithm. See also Checksum algorithm . A checksum algorithm is a signature algorithm that does not attempt to provide cryptographic protection against inversion. See also Signature algorithm . Corrupted Data is said to be corrupted if it has been modified without the user's authorization or approval.
Corruption is a subtle concept that can only be measured relative to a user's intent.
If a file is transferred across a phone line and a digit of a number is accidentally altered, the file is then corrupt. However, if the user were to enter the editor and make exactly the same change, the file would not be corrupt. A strong 16-bit CRC algorithm. A strong 32-bit CRC algorithm. A cryptographic hash algorithm is like a much wider, more powerful checksum.
