Integritätsprüfwerte
Integritätsprüfwerte, often referred to as checksums or hash values, are small, fixed-size data strings derived from a larger block of digital data. Their primary purpose is to detect accidental alterations or corruption of data during transmission or storage. The process of generating an integritätsprüfwert involves applying a specific algorithm to the original data. This algorithm is designed to produce a unique output for a given input. If even a single bit of the original data is changed, the resulting integritätsprüfwert will be significantly different.
When data is sent or stored, its corresponding integritätsprüfwert is typically transmitted or stored alongside it.
