I Had to install python in order to execute quip-apps in order to success.

Is there a way to use the Crypto.signWithCertificate() method using SHA-512?  We need to be able to sign a string using SHA-512, not any of the lower algorithms.

Several of the other Crypto methods support SHA-512, but the documentation (https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_classes_restful_crypto.htm) does not list 512, nor will it work when we tried it in our code:

Blob signedSecret = Crypto.signWithCertificate('SHA-512', blobSecret, certificateName);

Suggestions?
 

Hi All,
I got the following error verying the third step of the module:
"There was an unhandled exception. Please reference ID: PCUJKDWS. Error: Faraday::Error::ResourceNotFound. Message: NOT_FOUND: The requested resource does not exist".
I'm using a Development Environement with Lightning enabled; I got it by the particular form provided for Trailhead Lightning modules.
Let me know if you need more information.

Davide,
Thanks
