WebUnder this scenario, the hash value of the sever-side data is calculated and transferred to the client side where it is fed to CryptoMessage's new SignHash method. This method accepts a single argument, a CryptoBlob object populated with the hash value. Currently, only 20-byte values (SHA1) are supported as the input. WebNov 13, 2013 · Why does the RSACryptoServiceProvider.SignHash method only allow MD5 and SHA-1 to be used as hashing algorithms? 4. While I understand that the typical use case of asymmetric encryption is to encrypt with the public key and decrypt with the private key I believe that encrypting with the private key and decrypting with the public key is an equally …

If PSS isn't requiring that then that sounds like a bug with the PSS handler (though I'd have to dig in and double check). If you are signing data (which needs to be hashed first) then you should use SignData instead. It has no size restrictions. smart disability railroad
