WebNov 18, 2024 · TLS (the proper name for what you're calling SSL) does provide end-to-end integrity guarantees; that is, the receiver can know that what they got is exactly what the sender sent. However, it is a point-to-point protocol; any message (recorder) is from a specific sender and to a specific receiver. WebCryptographic checksums help authenticate files and their integrity. These algorithms also make it possible to acknowledge receipt of a file's last processing status. Checksums are used for applications such as the following: File integrity preservation.
