    • How to Check and Verify Mac SHA1 Checksum?
      • SHA1 value is commonly used to test whether the file is damaged or missing after distribution. Under normal circumstances, SHA1 authentication can check if the file is still the original one after transmission. If the SHA1 value can match with the one that provided by the distributor, then the file was not damaged or tampered. Here are the detail steps of how to verify Mac SHA1 checksum.
      • 1. Run terminal from Utilities and then type in syntax as well as the following syntex to check wanted files: shasum /path/to/file . For example, if you want to check the value of the "downloadfiles.dmg" on your desktop, then you can just input as follow: shasum ~/Desktop/downloadfiles.dmg.
      • 2. Then the test results will be similar to the following pic shows. The longest hexadecimal string is the SHA1 value of the file you've check.
      • Tips: If the file path is comparatively complex, then do not forget to take use of the drag characteristics of Mac OS X. After you enter "shasum ", you can directly drag and drop the test file into the terminal window. Then you will find that the patch of it will be automatically filled. The Shasum command can default detect SHA1 value.
    • Examples of Mac SHA1 Checksum Test
      • A classic example of this task is to directly download the upgrade package file from Apple official website and verify the SHA1 value of this downloaded file. The proper SHA1 value will be shown at the bottom of each downloaded upgrade package as wll as the pic shows below. The string can allow users to quickly check the completeness of the downloaded files.
    •  
      • Another common instance of SHA1 verification is to test whether the documents transmitted by P2P are complete and correct. And check if they were tampered in half-way of the transmission. One only need consult the file provider's website or inquiries to obtain the correct SHA1 value, and then compare it with their own test SHA1 value. If the two values ​​are the same, then the file is complete.
      • Ok. The above are all about Mac SHA1 checksum. If you want to get more tips and tricks on Mac, then you can just turn to our resource center to find more helpful skills.
