To do so, you must first download the appropriate ''checksum file'' from the same Sourceforge folder as your chosen ISO image. A checksum file will have the same name as the ISO image that it is to be used with; the only difference is that it will end in either ''-sha1.sum''' or '''-sha256.sum'''. For example, the appropriate checksum file for the ''manjaro-xfce-0.8.1-x86_64.iso'' file (64 bit Manjaro release 0.8.1 with the XFCE desktop) will be manjaro-xfce-0.8.1-x86_64'''-sha1.sum''', and/or manjaro-xfce-0.8.1-x86_64'''-sha256.sum'''. | To do so, you must first download the appropriate ''checksum file'' from the same Sourceforge folder as your chosen ISO image.

The 'sha' part of the checksum file name stands for '''S'''ecure '''H'''ash '''A'''lgorithm, which is used to generate a particular code unique to the downloaded ISO image; sha1 and sha256 are different versions of this algorithm that you can use to do this. While sha1 is the most widely used version, sha256 is a later and more secure version. Which you decide to use is entirely your choice. However, if you are unsure, then it is recommended to use sha256. | The 'sha' part of the checksum file name stands for '''S'''ecure '''H'''ash '''A'''lgorithm, which is used to generate a particular code unique to the downloaded ISO image; sha1 and sha256 are different versions of this algorithm that you can use to do this.
