Lacking sha1sum?

Posted on 11/12/2005, 5:36 am, by Colin Charles, under General.

So, I need my Fedora fix on x86. But I also wanted to verify disc 3 badly, seeing that I had to download it over many segments. Come OpenSSL to the rescue.

openssl dgst -sha1 FC4-i386-disc{1,2,3,4).iso

That magic command gave me the right sha1sum’s, to match with the SHA1SUM that is provided. man openssl and man dgst clearly helped!

    It appears to me that “openssl dgst -sha1” has a limit on the
    size of file it will work with.

    On Linux:
    -rw-r–r– 1 tdawson tdawson 2932811657 Sep 5 07:30 FC4-x86_64-DVD.iso
    [tdawson@tdawsond ~]$ openssl dgst -sha1 FC4-x86_64-DVD.iso
    FC4-x86_64-DVD.iso: File too large

    And on Solaris:

    -rw-r–r– 1 root sys 2932811657 Sep 4 21:03 FC4-x86_64-DVD.iso
    flo1cswstg # openssl dgst -sha1 FC4-x86_64-DVD.iso
    FC4-x86_64-DVD.iso: Value too large to be stored in data type
    flo1cswstg #
