WebJan 18, 2024 · Cryptography uses hashing to confirm that a file is unchanged. The simple explanation is that the same hashing method is used on a file at each end of an Internet download. The file is hashed on the web server by the web administrator, and the hash result is published. A user downloads the file and applies the same hash method. WebThis is especially true of cryptographic hash functions, which may be used to detect many data corruption errors and verify overall data integrity; if the computed checksum for the …
A database saves user passwords in a manner similar to a rainbow table. When your password is entered, the checksum is generated and compared with the one on record with your username.
