File Checksum Verifier is a program used to create and verify file checksums

«File Checksum Verifier» is a multifunctional tool for generating checksums (MD4 / MD5 / SHA1 / SHA256 / SHA384 / SHA512 / Tiger / Haval / RIPE-MD)

The checksum is a number obtained according to a special algorithm to ensure data integrity.

The sending computer calculates their checksum and appends it to the data packet. The computer receiving the data also calculates the checksum, but from the received data, and checks whether the sum obtained by it matches the sum received with the data packet. If not, it means that the data has been distorted.
