Subject: Fix the size of the hash array when checking sig hashes
X-Git-Url: https://git.sommitrealweird.co.uk/onak.git/commitdiff_plain/666b0d041ecf22f2b4936d3b04a98e5807f55877?ds=inline

Fix the size of the hash array when checking sig hashes

It was only 20 bytes - big enough for SHA1, but not when the larger
SHA2 hashes are available in nettle. This allows up to SHA512.
