Hi! I want to transfer RSA encrypted Data from a linux application to a .net webservice. I'm encrypting data with the method RSA_public_encrypt with RSA_PCKS1_OAEP_PADDING.
On the .net side i get the error: ---------------- System.Security.Cryptography.CryptographicException: Padding is invalid and cannot be removed. at System.Security.Cryptography.RijndaelManagedTransform.DecryptData(Byte[] inputBuffer, Int32 inputOffset, Int32 inputCount, Byte[]& outputBuffer, Int32 outputOffset, PaddingMode paddingMode, Boolean fLast) at System.Security.Cryptography.RijndaelManagedTransform.TransformFinalBlock(Byte[] inputBuffer, Int32 inputOffset, Int32 inputCount) at System.Security.Cryptography.CryptoStream.Read(Byte[] buffer, Int32 offset, Int32 count) ---------------- If i change the padding parameter to RSA_PKCS1_PADDING it get the different error: ---------------- System.Security.Cryptography.CryptographicException: Error occurred while decoding OAEP padding. at System.Security.Cryptography.Utils._DecryptPKWin2KEnh(SafeKeyHandle hPubKey, Byte[] key, Boolean fOAEP, Int32& hr) at System.Security.Cryptography.RSACryptoServiceProvider.Decrypt(Byte[] rgb, Boolean fOAEP) ---------------- So OAEP padding seem to be more correct. Does anybody know if i have to padd the buffer by using RSA_padding_add_PKCS1_OAEP() before giving the buffer to the encryption function or what can be wrong here? Any help is welcome... Bernd
