Creating an ECC CSR and installing your SSL certificate on your Apache server
Before generating an ECC CSR (Elliptic Curve Cryptography Certificate Signing Request) and ordering an ECC SSL Certificate form DigiCert, make sure that your environment is compatible with ECC SSL Certificates. For more information about Elliptic Curve Cryptography, see Elliptic Curve Cryptography ECC Explained.

- Is there a openssl command that can generate an ECC key pair. Openssl command that can generate an ECC key pair. Generate ECC key with password protection.
- Generate an EC private key, of size 256, and output it to a file named key.pem: openssl ecparam -name prime256v1 -genkey -noout -out key.pem. Extract the public key from the key pair, which can be used in a certificate: openssl ec -in key.pem -pubout -out public.pem read EC key writing EC key.
- Oct 31, 2016 My scenario is generate key pair using openSSL, sign with openSSL & do verification with micro-ecc. Can you please share if you have any sample code for this? My confusion was how we can convert key structure of openSSL to suit as input to.

Apache: How to Create Your ECC CSR
- Log into your Apache server.
- At the prompt, type the following command to generate an ECC private key using the OpenSSL ecparam tool to generate your .key file:
openssl ecparam -out server.key -name prime256v1 -genkey
Where server is the name of your server.Note: Recommended ECC key size is 256-bit. If greater encryption strength is required, your other private key option is secp384r1. - Save (backup) the generated .key file, making sure to note its location. This private key is required later for ECC SSL Certificate installation.
- Next, type the following command to generate a ECC certificate signing request (CSR):
openssl req -new -key server.key -out server.csr -sha256
Where server is the name of your server. - As you are prompted, enter the following information:For fields that are not required, you can enter '.' and those fields will be left blank.
Country Name (2 letter code) [AU]: Type the two letter code for the country where your company is legally located. State or Province Name (full name) [Some-State]: Type the name of the state or providence where your company is legally located. Locality Name (eg, city) [ ]: Type the name of the city where your company is legally located. Organization Name (eg, company) [Internet Widgits Pty Ltd]: Type your company's legally registered name. Organizational Unit Name (eg, section) [ ]: Type the name of the department within your organization that you want to appear on the ECC SSL Certificate. Common Name (e.g. server FQDN) [ ]: Type the fully qualified domain name (i.e. www.example.com) for the site that you are securing.
Note: If you are generating an Apache CSR for a Wildcard SSL Certificate, your common name should start with an asterisk (e.g., *.example.com). - This creates your openssl.csr file.
- Now, open the .csr file with a text editor and copy the text of your CSR, including the -----BEGIN NEW CERTIFICATE REQUEST----- and -----END NEW CERTIFICATE REQUEST----- tags, and paste it into the DigiCert order form.Note: During your DigiCert SSL Certificate ordering process, when asked to Select Server Software, make sure that you select Apache. This option ensures that you receive all the required certificates for Apache certificate installation.
