Hi Bouncy Castle C# Devs, First of all I would like to thank you for doing such a great job with Bouncy Castle library.
I need to code following openssl-sign-instruction in C# with BouncyCastle: openssl dgst -sha256 -binary -out "signaturefile".sig -sigopt rsa_padding_mode:pss -sigopt rsa_pss_saltlen:-1 -sign "privatekey".pem "file2sign" There is a Java solution in: https://stackoverflow.com/questions/53728536/how-to-sign-with-rsassa-pss-in-java-correctly Security.addProvider(new BouncyCastleProvider()); Signature signatureSHA256Java = Signature.getInstance("SHA256withRSA/PSS"); signatureSHA256Java.*setParameter*(new *PSSParameterSpec*("SHA-256", "MGF1", MGF1ParameterSpec.SHA256, 32, 1)); signatureSHA256Java.initSign(KeyManagerHelper.getPrivateKeyFromKeyStore("privatekey")); signatureSHA256Java.update(byteArray); byte[] signSHA256Java = signatureSHA256Java.sign(); // after that I compare the Java-sign-bytearry with the openssl one System.out.println("signSHA256Java == signSHA256Openssl:\n" + Arrays.equals(signSHA256Java, signSHA256Openssl)); However when I checked your C# code it seems that *PSSParameterSpec and Signature.setParameter are* still not yet implemented, although you have placeholders in the code -e.g. // try // { // signature.setParameter(sigParams.getParameterSpec(PSSParameterSpec.class)); // } I wonder if there is a newer version that has this implemented or there is some other way how to implement above openSSL command ( openssl dgst -sha256 -binary -out "signaturefile".sig -sigopt rsa_padding_mode:pss -sigopt rsa_pss_saltlen:-1 -sign "privatekey".pem "file2sign" ) with BouncyCastle? Many Thanks Mickey P.S. I am using bccrypto-csharp-1.8.6 (the latest version I found on your site)
