Hi,


Please let me know how to use crypto calls such as CryptSignMessage that are used in windows in xcode.


Best Regards,

Alas, I don't know what 

CryptSignMessage
does; you will have to ask your question in terms of the behaviour you want. Is it a low-level signing operation? Or a high-level CMS operation?

ps I moved the thread over to Core OS > Security, which is a great home for questions like this.

Share and Enjoy

According to the Windows documentation, CryptSignMessage hashes a blob of data, signs the resulting hash, and then returns a blob containing both the hash and the original message in PKCS#7 ASN.1 format.


So I think CMS is probably the right equivalent.
