Hi, I am facing an issue while I am trying to create a sample self-signed certificate using openssl -req for EC Cipher suites.
*Requirement:* I need to install a self-signed certificate for the cipher suite ECDH-RSA-AES128-SHA which has the following attributes:- 1. Signature Algorithm: *sha1WithRSAEncryption* and 2. *EC Public Key *with curve type as* prime256v1.* I tried the following open-ssl commands but ended up with a certificate that has a signature algorithm as *ecdsa-with-SHA1 with an EC Public Key *having curve type as *prime256v1.* a>* openssl ecparam -out ec_rsa_key.pem -name prime256v1 -genkey* b> *openssl req -new -x509 -days 365 -key ec_rsa_key.pem -sha1 -out ec_rsa.pem* What could I be missing here? Or is there any downloadable sample certificates & private key which has the required attributes? Regards Tanmoy Sinha
