Hi Germán and Paul,
I apologize too. I missed the request for Paul to be added. Paul I have added you as a developer on Cryptography.
Germán would you like to be an admin on the group?
Please let me know if you need anything else.
Ron Teitelbaum Cryptography Team Leader

accessing
crypt(3) through FFI.
Hi Paul:
Sorry the delayed response, but I miss this mail in the Crypto list.
Having tried the Blowfish implementation, I think is very good and you
should
publish all the stuff (including Bcrypt) in the squeaksource Cryptography project. Unfortunately I'm only a developer and can't grant permits to you but I think that soon the administrators will do.
In the maintime if you can send me the latest .mcz of the Blowfish to continue playing with it I will appreciate.
Cheers and very good job.
Germán.

Hi -
I've made a working implementation of the Blowfish algorithm in Pharo, a partially broken implementation of Bcrypt in Pharo, and a reliable way to access the linux crypt library using FFI in Pharo on linux.
At the moment it takes about 25 seconds to hash a password using my Bcrypt implementation in Pharo, which is about 50x too long. So I'm going to try to get a FFI version put together or just use SHA512 from the linux crypt library. I have learned a lot but don't expect to fix the improper hashing as I don't think the fix would cause a massive speed up. I think the hashing error is probably an off-by-one error in
an
array index in the BCrypt class.
Ruby, Python, Lisp, PHP all access a C or Java library for bcrypt which probably should have told me something.
I could either make a SqueakSource repository for all this or put it in the Cryptography package. Or I can email anyone the mcz files off list that would like them.
Let me know how to proceed when you get a chance.
Thanks
