sha1(sha1($pass) confused. - inoo - 12-21-2013
Hello,
I have a question about 2 hash type distinguishing
It is hard to identify MySQL4.1/MySQL5(htype=300) and sha1(sha1($pass)) (htype=4500)
as reference;
http://www.palominodb.com/blog/2011/12/04/hashing-algorithm-mysql-password
I doubt that just two hashtype is the same(exact) hash except between Uppercased hash(300) and Lowercased hash(4500), as memtioned Example hashes pages
pls , explain me about difference of two hashtype..

That's simple, the -m 300 uses the binary digest from the first sha1() as input for the 2nd sha1() while -m 4500 uses the ascii hex representation of the first sha1().

Thanks for your reply.
All of MySQL v4.1/v5 applications use the binary digest sha1( <-- raw sha1($pass)), is right?
overall, I'd like to know that what kind of applications use 4500 hashtype( sha1( <--asciihex rep( sha1($pass)) ?
I appreciate for your great job!!!
