Re: [openssl-users] An error occurred while using the d2i_RSAPublicKey function.

Thank you viktor, Actually, I'm begginer so I don't know well. You said that the my input data is not a PKCS # 1 public key type. How do I distinguish between a PKCS # 1 type or an X.509 SPKI Public Key? -- Sent from: http://openssl.6102.n7.nabble.com/OpenSSL-User-f3.html -- openssl-users mai

I am getting RSA publickey from the server. I need to extract the modulus and public exponent from the key to do the RSA operation. I have to solve with C language code, not shell command. I have written the following test code, and an error has occurred in the d2i_RSAPublicKey function. A null p

Re: [openssl-users] how to import external rsa public key in openssl.

Thanks Matt for your reply. The purpose I am doing this is to find the modulus and exponent in the RSA public key. My sample code and the current results are shown below. = void fnStr2Hex(char* out, char* in) { int data_len = strlen(

I would like to perform operations such as RSA signature verification through an RSA public key file received from an external server. Key values are given in der format or pem format as follows. der:"30820122300d06092a864886f70d01010105000382010f003082010a02820101008ab8c549138cc59f605b50265f69e
