The hash() function defaults to use MD5 so I'm not sure why you'd be
getting different values from openssl. I just tested things and I don't
get different values from openssl.
To test, I created a test.txt file containing "This is a test of the MD5
hash". I then ran the following code on OpenBD:
<cffile action="read" file="#ExpandPath('test.txt')#" variable="foo" />
<cfset fooHash = Hash(foo) />
<cfoutput>#fooHash#</cfoutput>
This output:
31C30AF062B9CEF1647ECB4A2CB1F9DA
I then checked using Linux's md5sum command against test.txt, which output:
31c30af062b9cef1647ecb4a2cb1f9da test.txt
I then checked using openssl md5 test.txt which output:
MD5(test.txt)= 31c30af062b9cef1647ecb4a2cb1f9da
So at least in my testing, other than the output from OpenBD being all
upper case, the MD5 values are the same.
Are you sure there isn't something else in the mix throwing things off?
Do you have code you can share?
