Re: [openssl-users] RSA sign using SHA256 with mgf1 padding

Hi, I have written a sample few years ago that performs PSS signature using SHA256 like what you need. You can get it from https://www.idrix.fr/Root/Samples/openssl_pss_signature.c It uses the maximum salt length. You should check that the server expects this as well. Cheers, -- Mounir IDRASSI L

[openssl-users] RSA sign using SHA256 with mgf1 padding

Hello, I'm running an application which runs an authentication session with a server. The server provides some random data, and my application needs to sign it with its private key, and send back the signature. The server which knows the public key verifies the signature, and it good then the cl

[openssl-users] RSA sign message

Hi, I need to RSA sign a message using SHA256 as hash and PKCS1 v1.5 as padding. I am however confused about the *type* parameter of RSA_sign function [0] What is the value that I should use for *type* in my particular case? Thanks, Gabriel [0] https://www.openssl.org/docs/manmaster/crypto

RSA sign

dear all i have a client server client application the server should created an encrypted shared key and some data and make digest of both of them (data and encrypted shared key) as an input to SHA1 then the server should sign the output of the hash with function SignDigest() which include function

RSA sign/verify padding modes

Hi All I'm trying to use RSA_private_encrypt/RSA_public_decrypt for low level access to sign/verify operations. The documentation for these functions state that RSA_PKCS1_PADDING and RSA_NO_PADDING are the only supported padding modes, whereas when i look at the source code (0.9.8b:crypto\rsa\rsa
