Is it just me or is the WIKI backward?
Code: Select all
rawdigest = love.data.hash( hashFunction, data )
It only seems to work for me if the arguments are reversed???
Code: Select all
rawdigest = love.data.hash( data, hashFunction )

As far as i can tell from the source, the wiki's order should be the one that works...

Code: Select all
rawdigest = love.data.hash('sha1', '')
for i = 1, #rawdigest do
io.write(string.format("%02x", rawdigest:byte(i)))
end
print()
works for me, printing da39a3ee5e6b4b0d3255bfef95601890afd80709 which is the SHA-1 hash of the empty string as explained in
https://en.wikipedia.org/wiki/SHA-1. So the wiki order is correct.
If I invert them I get this:
Code: Select all
Error: main.lua:1: Invalid hash function '', expected one of: 'md5', 'sha1', 'sha224', 'sha256', 'sha384', 'sha512'

As I expected - my bad.
I overwrote the function in a library.
