When the user logs in, you use the same hashing function to generate a hashed version-and compare that to the hashed version you have in SQL . That makes it hard for hackers to get people's passwords by hacking your SQL server.

The hashing function appends the fixed string 258EAFA5-E914-47DA-95CA-C5AB0DC85B11 ( a GUID ) to the value from Sec-WebSocket-Key header ( which is not decoded from base64 ), applies the SHA-1 hashing function, and encodes the result using base64.

Internally, VirtualGL's interposer engine also maintains a map of windows to Pbuffers, matches visual attributes between the destination X display ( the " 2D X Server " ) and the 3D X Server, and performs a variety of other hashing functions to assure that the GLX redirection is seamless.

:The common python libraries should have built in hashing functions that you should be able to give a pointer to the file directly ( I'm not a python programmer so my terminology may be off ) and it will transparently handle this for you, without having to worry about memory issues.
26.
The attacker knows that the state behind the hashed key / message pair for the original message is identical to that of new message up to the final " & . " The attacker also knows the hash digest at this point, which means they know the internal state of the hashing function at that point.
27.
In order to sign this new message, typically the attacker would need to know the key the message was signed with, and generate a new signature by generating a new MAC . However, with a length extension attack, it is possible to feed the hash ( the signature given above ) into the state of the hashing function, and continue where the original request had left off, so long as you know the length of the original request.

A suitable password hashing function, such as bcrypt, is many orders of magnitude better than a naive function like simple MD5 or SHA . A user-selected eight-character password with numbers, mixed case, and symbols, with commonly selected passwords and other dictionary matches filtered out, reaches an estimated 30-bit strength, according to NIST . 2 30 is only one billion permutations and would be cracked in seconds if the hashing function is naive.

It is just a hashing function; there are at least three implementations linked to at the bottom of the article, and if you wanted it in another language I am betting you could just google " WHIRLPOOL HASH FUNCTION " and the language in question ( i . e . PHP or Javascript ) and probably end up with it, if it is easily available .-- 24.147.86.187 22 : 56, 31 August 2007 ( UTC)
