Re: [Pharo-users] SHA256 hashing with secret key..

to me it shows that the package crypto should be improved. So publish a new version with the helper methods once you get the right way of making it work. We are all newbies in a domain or another one and I want a system for newbies (with documentation, nice comment, API, testsâ¦.).

Pharo on Ubuntu ARM

by Marc Hanisch

Hello, I'm running Ubuntu ARM (armhf) on my Toshiba AC100. With the help of apt-get I've installed the squeak-vm and the squeak-image, which both run fine. Now I've downloaded the Pharo-image, but could not find the cog-vm for ARM. Running the Pharo-image with the squeak-vm just gives me a segmentation fault: -1550458048 [] in ByteSymbol>? /usr/bin/squeak: line 277: 4603 Segmentation fault (core dumped) $VM I don't know if it is in general possible to run the image with the squeak-vm. Does an ARM-build for the cog-vm exists? Thanks in advance, Marc

CogVM version

by Francois Stephany

I've downloaded the Cog-mac.zip from: http://www.pharo-project.org/pharo-download/unstable-2-0 How can I find out the version/revision number? It would be cool to have the number in the file name.

You need an HMAC signed SHA256 secret. https://en.wikipedia.org/wiki/HMAC https://en.wikipedia.org/wiki/SHA-2 First step is to get the correct SHA256 part then the second step is to make it the correct HMAC Does that help?

When set to TRUE, outputs raw binary data. FALSE outputs lowercase hexits. so, i think i need to use the apiSecret as the key for encryption.. -- ---- peace, sergio photographer, journalist, visionary http://www.ThoseOptimizeGuys.com http://www.CodingForHire.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101
