'''SFV''' is an [[acronym]] for ''simple file verification'', a [[checksum]] format using the [[CRC32]] algorithm to verify the integrity of files. [[CRC32]], and thus also SFV, is not an ideal format for [[Computer security|securely]] verifying data integrity, since the CRC32 format is vulnerable to intentional modification that cannot be detected. Other formats, such as [[SHA512]], are better suited for ensuring the authenticity of files.

[[MD5]] have also been used for this purpose, but it's not prone to the same attacks (after the discovery of an MD5 hash collision in August 2004, claimed to be found in only 1 hour on a low-gardegrade computing cluster).
