Seriously misleading description, now fixed

This fragment "(.. bcrypt computes..) a hash from a given input as follows: bcrypt(cost, salt, key, input)" suggested that the password is fed in input. But the intend in the original definition, and many implementations, is feeding password in key, with input a constant derived from "OrpheanBeholderScryDoubt" broken as three 64-bit blocks. Now fixed. Fgrieu (talk) 20:27, 26 June 2012 (UTC)[reply]

Popular password hashing bcrypt vs later obscure file encryption bcrypt

I bet 99% of people looking for bcrypt think of the password derivation function, not a pretty obscure program using an outdated cipher... JidGom (talk) (2011-03-30T04:58:28)

We had the same thought on the same day. Right - all the links to bcrypt on wikipedia were about the hash. And the hash is about more than the "crypt (Unix)" program. So I fixed it. ★NealMcB★ (talk) 15:35, 30 March 2011 (UTC)[reply]

Cryptographic hash function page

Why isn't this page listed in the Cryptographic hash function page and corresponding template? Dserodio (talk) 20:32, 20 August 2012 (UTC)[reply]

Technically it's not a hash, it's a Key derivation function.

Explain What Bcrypt Does, Not How It Is Implemented

The article lacks a clear statement about how Bcrypt is different from other hashing functions. What parts are essential to its functioning and how it may be used. I.e. something that would speak to the broader audience of people not versed in cryptography, users of cryptography, not cryptographers themselves. An explanation would be especially beneficial because most times I've seen it being used, it was used wrongly. The fact that it uses the hash, previously generated from input to produce the salt when verifying that the hash generated from another input matches the hash generated from the previous input - is very counter-intuitive and deserves special attention IMO. 79.176.130.107 (talk) 14:02, 9 October 2013 (UTC)[reply]

ExpandKey function is weird

what I can see: it takes an input, does lots of stuff, discards it and returns the input state.
