'''Simple file verification''' ('''SFV''') is a file format for storing [[CRC32]] [[checksum]]s of files to verify the integrity of files. SFV is used to verify that a file has not been [[data corruption|corrupted]], but it does not otherwise verify the file's [[Information security#Authenticity|authenticity]]. The {{mono|<code>.sfv}}</code> [[file extension]] is usually used for SFV files.<ref name="stealthisbook"/>
