Use RSASSA-PSS with CryptoAPI RRS feed

  • Question

  • Hi, i am trying to verify a signature created with a from an extern application with RSASSA-PSS. Is it possible to use the functions of CryptoAPI, like CryptVerifySignature, or even CryptSignMessage with this signing method? I didn't see any otpions related to it for these functions.

     Thanks for your time

  • I don't think the PSS padding scheme is supported by the original CryptoAPI (it's too new), but it is available in CNG's BCryptVerifySignature function .
