Unix crypt() function in smalltalk/pharo

Question

I want to encode passwords for UNIX accounts using the crypt function. I'm using pharo 1.0. I tried to install the crypto package from squeakmap, but it gaves me an error and the package seem to get partially installed (categories without class).

How can I get my password crypted? I'm willing to invoke external code, if it is required (and there's a package in SqueakMap that makes the trick in pharo).

Thanks.

Answer 1

Look if you have a category System-Digital Signatures in your image, with a class SecureHashAlgorithm. You can then hash your password as follows:

(SecureHashAlgorithm new hashMessage: 'my password') asString

Answer 2

In Pharo check the category: System-Hashing.

There you have MD5 and SHA.

Classes: SHA1, MD5NonPrimitive, MD5.

Those classes were extracted from the crypto package from squeaksource, and make them work in Pharo. Then MD5 and SHA were integrated in the core.

Cheers

Answer 3

There is the PasswordHashingFFI package in the Cryptography repository that uses FFI to access the crypt(3) library on linux.

Its here:

http://www.squeaksource.com/Cryptography.html

Use is like

CryptLinuxFFI sha256:'1234'

OSProcess can be used to call any external program. Have a look at http://book.pharo-project.org/book/PharoTools/OSProcess/
