Question

hashing password with bcrypt in coldfusion


Hello

    I am trying to hash a password with bcrypt algorithm (try to match password with an off the shell software), but I keep getting error, it works for algorithms "SHA-1", "SHA-256" etc...<cfset hashpw = #hash(password_from_form, "SHA-1")#>, <cfset hashpw = #hash(password_from_form, "SHA-256")#>

   but  <cfset hashpw = #hash(password_from_form, "BCrypt")> don't work,  got error : The BCrypt is not supported by the security Provider you have chosen.

   Is there no bcrypt algorithm in coldfusion hash function ?

   Have been working on it over a week but without luck.

   btw, I am using dreamweaver 8.

    thank you so much in advance.

    I realize I'm responding to this post 5 years after it was made, but I just want to share that CF2021 has added a bcrypt function. Even if it may be too late for the folks who participated on this thread in the past I share it because this post is one of the first results that comes up in google search on coldfusion and bcrypt. Here's a link to the new docs:

      Coldfusion doesn't support bcrypt in the hash function. You will have to use a java version and integrate it.

      You can do something like this : http://www.aliaspooryorik.com/blog/index.cfm/e/posts.details/post/using-bcrypt-in-coldfusion-10-370

      This is for CF10 / 11 but there are various similar ways and post online about this depending on the version of Coldfusion you use. Let me google that for you

      sorry I was out for a few days.

      thank you so much for the info. I am using dreamweaver 8 but in the process of converting it to cf11.

      The code is kind of complicated for me, but I will digest it slowly, I will let you know what happens.

      thanks again.
