I am converting 20,000+ users from mybb to a new rails app.  
It appears that ruby m5 crypts different than php md5.

Is this possible? I thought the algorithm should be the same for any  
platform.

I expect it should be the same. Are you sure that mybb only does an  
MD5. I was looking at YABB a long time back, and I seem to recollect  
that it carries out 2 operations on the password. IIRC, it was Base64  
and MD5 or something like that.

Hope this helps.

Cheers,  
Mohit.

Yes that was it, they actually encrypt the password and salt 2x with  
md5. I don’t read php so it took me a while to figure out.  
Thanks
