I have a list of files with corresponding SHA256 hash values that I need to download and verify. After looking at the documentation for aria2c, I found that you can specify a hash value for the download so that aria2c can verify the integrity. The problem I'm having is how to specify the hash values within an input file. My input file is as follows:
https://esgf.ceda.ac.uk/thredds/fileServer/esg_cmip6/CMIP6/HighResMIP/CMCC/CMCC-CM2-VHR4/highresSST-future/r1i1p1f1/Amon/hur/gn/v20190725/hur_Amon_CMCC-CM2-VHR4_highresSST-future_r1i1p1f1_gn_201501-201501.nc
checksum=sha-256=86242dbe5cec36208eb1a47c3bdcad439071f4c954e99e9a1950be6e4f6f3015

checksum=sha-256=db74f6b30acc5691cf11e5b69c943f27856fe1f6e8f252b4061febf2deadd6cb
and I invoke aria2c like:
aria2c --http-user='' --http-passwd='' -i test.txt
But I'm getting the following error:
Exception caught
Exception: [AbstractOptionHandler.cc:69] errorCode=28 We encountered a problem while processing the option '--checksum'.
-> [OptionHandlerImpl.cc:395] errorCode=1 Unrecognized checksum
I have tried to do download a single file with checksum verification and it works:
aria2c --http-user='' --http-passwd='' https://esgf.ceda.ac.uk/thredds/fileServer/esg_cmip6/CMIP6/HighResMIP/CMCC/CMCC-CM2-VHR4/highresSST-future/r1i1p1f1/Amon/hur/gn/v20190725/hur_Amon_CMCC-CM2-VHR4_highresSST-future_r1i1p1f1_gn_201503-201503.nc -V --checksum=sha-256=db74f6b30acc5691cf11e5b69c943f27856fe1f6e8f252b4061febf2deadd6cd
Where did I go wrong?
Note: You'll need a username and password to download these files.
