Situation



I'm on FreeBSD 11.2 without GUI. I'm brand new to BSD systems.



Suppose we have a SHA512SUM file generated on FreeBSD with:



sha512 encrypt-file-aes256 decrypt-file-aes256 > SHA512SUM


It looks different from the Linux format, which from Linux can be generated using --tag switch:



SHA512 (encrypt-file-aes256) = 9170caaa45303d2e5f04c21732500980f3b06fc361018f953127506b56d3f2f46c95efdc291e160dd80e39b5304f327d83fe72c625ab5f31660db9c99dbfd017
SHA512 (decrypt-file-aes256) = 893693eec618542b0b95051952f9258824fe7004c360f8e6056a51638592510a704e27b707b9176febca655b7df581c9a6e2220b6511e8426c1501f6b2dd48a9


Question



How do I check this file? There is no --check option in the man page.



Progress



So far, I am only able to manually test a single file with hard-coding the hash sum:



sha512 -c "9170caaa45303d2e5f04c21732500980f3b06fc361018f953127506b56d3f2f46c95efdc291e160dd80e39b5304f327d83fe72c625ab5f31660db9c99dbfd017" encrypt-file-aes256 && echo $?


Scripting-wise, I don't yet see a way of checking the whole SHA512SUM file automatically.



Note, that it may contain many more files than the two as in my case.

          You can use the shasum (man page) tool, which has a -c option to check against a checksum file and is a front-end to the several checksum algorithms including SHA-512.



          In your case, this command should be enough to check both files:



          $ shasum -a 512 -c SHA512SUM


          If you use a truncated checksum (such as SHA-512/256) you might need to select the algorithm explicitly through the -a option. But it should not be necessary.



          Note, that you have to use the standard (Linux) format of SHA512SUM file in order for the check to succeed, otherwise you'd get a confusing error:



           no properly formatted sha1 checksum lines found

This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods. Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of ...
