Recommendation for password encryption?
by Mariano Martinez Peck Sept. 30, 2022

Sept. 30, 2022

Hi guys. Some time ago I asked about the best way to encrypt a password. Some of the recommendations I got was: 1) Generally for passwords you do not write a decrypt method for security purposes (eg you do not want people to be able to reverse engineer the encrypted password easily) 2) put a little salt 3) There is http://www.squeaksource.com/Cryptography/PasswordHashingFFI 4) I should not decrypt password but instead I should compare both encrypted versions to see if they are equal. My scenario is the following. I need to store database passwords in text files. So I don't want to let them as plain text. And while I understand 4), I think it's a different scenario than mine. I know that some database driver may allow you to directly send the encrypted password. But still...I have another similar scenario in which I have to store a password and then send it (unencrypted)...so I kind of really need a bi-directional encryption. Now..I would try to avoid having an external library + FFI. Any ideas what is the best thing I can do? And how could I solve 1) if I want bidirectional like in my case? Thanks in advance, -- Mariano http://marianopeck.wordpress.com

Progress Report -> Refactoring Project - ( February 8 - 12 )
by Evelyn Cusi Lopez Feb. 24, 2021

Feb. 24, 2021

Hi all Last week I did these tasks: - Add preview to select variables when running the generate accessors command (Fix issue #5270 <https://github.com/pharo-project/pharo/issues/5270>). - Separate the link between views and refactorings (setUp and pushDown method refactoring). - Add generic previews and remove specific previews of PushUp and PushDown refactoring (https://github.com/pharo-project/pharo/pull/8553) - I started the modification to make refactorings only in some packages, add a searcher for classes and methods in packages (these have reference to the package internally), I still have to finish implementing this part so that it is updated correctly when there are changes, deletions and additions. Fix issues #8513 <https://github.com/pharo-project/pharo/issues/8513>, #6366 <https://github.com/pharo-project/pharo/issues/6366>. - Improve "Move method to class side" Refactoring, the new version catch broken references (method senders and direct access to instVar) and fix them ( https://github.com/pharo-project/pharo/compare/Pharo9.0...Lin777:NewMoveToC…) for instance: Before refactoring: *RBTransformationRuleTestData* >> rewriteUsing: searchReplacer rewriteRule := searchReplacer. self resetResult. After refactoring: *RBTransformationRuleTestData* >> rewriteUsing: searchReplacer ^ self class rewriteUsing: searchReplace. *RBTransformationRuleTestData* *class* >> rewriteUsing: searchReplacer | aRBTransformationRuleTestData | aRBTransformationRuleTestData := self new. aRBTransformationRuleTestData rewriteRule: searchReplacer. aRBTransformationRuleTestData resetResult'). ----------------------------------------------------------------------- Tasks for this week: - Improve extract setUp refactoring. - Finish to rename methods in specific packages (Fix issues #8513 <https://github.com/pharo-project/pharo/issues/8513>, #6366 <https://github.com/pharo-project/pharo/issues/6366>.) - Improve messages when exists a Warnings or Expections in refactorings. - Fix move to component refactoring issue ( #8499 <https://github.com/pharo-project/pharo/issues/8499>) - Fix extract method issue (#5855 <https://github.com/pharo-project/pharo/issues/5855>) - Check if it is better to change the behavior of the "Remove method" command, using a refactoring instead of a strategy Cheers, Evelyn

by StÃ©phane Ducasse Feb. 18, 2021

Feb. 18, 2021

Hello happy Pharoers Today we could access our building where the M1 machine is and Pablo packaged it so that you can test the first version. Pablo wrote a little blog post for you. https://thepharo.dev/2021/02/16/first-apple-m1-pharo-version/ Let us since we do not have the M1 at hand and waiting to be able to make it accessible from our build farmâ¦ but we are not responsible for it and we were waitingâ¦. But the crew was fixing other VM glitches. So we will be ready soon to focus on the Jit version.
