To compute the SHA256 cryptographic hash or checksum – sha256sum test.iso Now, understand it with the help of an example. SHA256 basically outputs a value which is 256 bits long. sha256sum command-line utility is mainly used to check and compute SHA256 message digest. We would cover sha256sum command-line utility here. In Ubuntu, there are numerous command-line utilities available to verify checksum. In other words, we can say if the checksum matches then there the no errors in the stored data.Ĭhecksum is basically used to detect errors in the stored data, which could have crept in while storing or transmitting the data. If the recalculated checksum and the checksum we calculated for the first time matches.
Later, if we want to check whether the data is still valid or not, we need to recalculate the checksum for the stored data again. For that, we need to first know the checksum of the data and store it. With the help of a checksum we can identify whether the data we have stored in the memory is still valid or not. In this article, we would cover how to verify checksum in Ubuntu.
