  • Generate digital signature using VBA

    - by tputkonen
    I have text cells of arbitrary length in Excel's column A. Using a private key, I want to generate digital signature for data in column A into the cell in column B. I'm looking for a macro implementation for the digital signature algorithm - I don't think one ships with Excel, but is there an addon available?

  • Custom warning in Xcode

    - by maximumnamelength
    I'm working on an API library and I'd like to add a few warnings that would appear when another developers builds the app if an optional apikey is not included. It should be buildable w/o the key (since it's optional) so I can't just add a syntax error to force a build error. I know Xcode supports TODO and FIXME but those aren't really highlighted anywhere major. Any other thoughts on how to approach this?
