different results between julia 1.10 vs osx builtin

[jonalm]

consider the following (on mac M2)

> echo "asdpfginpqvwen" >> foo
> md5 foo
MD5 (foo) = 610d6da0969779be0e9c6c1386218660

Now opening julia 1.10 and MD5 v0.2.2, I get

julia> using MD5
julia> bytes2hex(md5("foo"))
"acbd18db4cc2f85cedef654fccc4a4d8"

How come these results are different?

In your first code block, you run the command md5 foo which reads the content of the file "foo" and runs the MD5 hash of its contents. In addition, I believe the echo command also adds a newline character to the end of the input. On my machine the hash seems to match your expected output:

julia> bytes2hex(md5("asdpfginpqvwen\n"))
"610d6da0969779be0e9c6c1386218660"

In the second code block, you use julia to run the MD5 hash of the string "foo". In order to run the hash on the contents, you would want something like:

open("foo") do f
     bytes2hex(md5(f))
end

Many thanks @BonelessPi!
