makecert.exe option '-sky'? RRS feed

  • Question

  • I am not quite understand the option '-sky' of makecert.exe. it is described as to specify the type of subject key, which can be 'signature' or 'exchange'. so what do we mean by 'exchange'?

    Could anyone know tell me someting about this?

  • Hey Justin,

    Sorry for not clearing that up earlier. Here is an explanation of those two options:

    'signature'  (AT_SIGNATURE) - the certificate can only be used to sign a payload
    'exchange' (AT_KEYEXCHANGE) - the certifiacte can be used to sign AND/OR encrypt a payload

    There is some docs on these key specs in the cryptography platform sdk

    Hope this helps
