Jan 01, 2014  New Standard for SSL Certificates Industry standards set by the Certification Authority/Browser (CA/B) Forum require that certificates issued after January 1, 2014 MUST be at least 2048-bit key length. As computer power increases, anything less than 2048-bit certificates are at risk of being compromised by hackers with sophisticated processing capabilities. Please select what kind of key you want: (1) RSA and RSA (default) (2) DSA and Elgamal (3) DSA (sign only) (4) RSA (sign only) Your selection? 1 RSA keys may be between 1024 and 4096 bits long. And select 2048-bit (as Gnuk Token only suppurt this). What keysize do you want? (2048) Requested keysize is 2048 bits. Before you can order an SSL certificate, it is recommended that you generate a Certificate Signing Request (CSR) from your server or device. Learn more about SSL certificates » A CSR is an encoded file that provides you with a standardized way to send DigiCert your public key as well as some information that identifies your company and domain.

What is a CSR? A CSR or Certificate Signing request is a block of encoded text that is given to a Certificate Authority when applying for an SSL Certificate. It is usually generated on the server where the certificate will be installed and contains information that will be included in the certificate such as the organization name, common name (domain name), locality, and country. It also contains the public key that will be included in the certificate. A private key is usually created at the same time that you create the CSR, making a key pair. A CSR is generally encoded using ASN.1 according to the PKCS #10 specification.

A certificate authority will use a CSR to create your SSL certificate, but it does not need your private key. You need to keep your private key secret. The certificate created with a particular CSR will only work with the private key that was generated with it. So if you lose the private key, the certificate will no longer work.

Advise to use at least a 2048-bit key, which is the minimum for EV certificates. Fill out your information in the “Generate a New Certificate Signing Request” form. Click “Generate.”. Under “General Properties,” you can give the certificate a name to identify it.

What does a CSR look like?

Most CSRs are created in the Base-64 encoded PEM format. This format includes the '-----BEGIN CERTIFICATE REQUEST-----' and '-----END CERTIFICATE REQUEST-----' lines at the begining and end of the CSR. A PEM format CSR can be opened in a text editor and looks like the following example:

-----BEGIN CERTIFICATE REQUEST-----

How do I generate a CSR and private key?

You need to generate a CSR and private key on the server that the certificate will be used on. You can find instructions in your server documentation or try the instructions from one of these certificate authorities:

Android keystore generate. The public key raw data is accesible using byte publickey = keyStore.getCertificate(alias).getPublicKey.getEncoded. You will need to convert it to base64 to send it to server as String – pedrofb Feb 10 '17 at 12:29. To generate the key, use a KeyPairGenerator with KeyPairGeneratorSpec: /. Generate a new EC key pair entry in the Android Keystore by. using the KeyPairGenerator API. The private key can only be. used for signing or verification and only with SHA-256 or. SHA-512 as the message digest.

DigiCert CSR Generation Instructions
Entrust CSR Generation Instructions
GeoTrust CSR Generation Instructions
Thawte CSR Generation Instructions

Once you have your CSR generated, you can use our SSL Wizard to find the best SSL certificate that will meet your needs. If you are familiar with OpenSSL you can use the following command to generate a CSR and private key:

openssl req -new -newkey rsa:2048 -nodes -out servername.csr -keyout servername.key

How do I decode a CSR?

You can easily decode your CSR to see what is in it by using our CSR Decoder. In order to decode a CSR on your own machine using OpenSSL, use the following command:

openssl req -in server.csr -noout -text

What is a CSR/Private Key's bit length?

The bit-length of a CSR and private key pair determine how easily the key can be cracked using brute force methods. As of 2016, a key size of less than 2048 bits is considered weak and could potentially be broken in a few months or less with enough computing power. If a private key is broken, all the connections initiated with it would be exposed to whomever had the key. The Extended Validation guidelines that SSL certificate providers are required to follow, require that all EV certificates use a 2048-bit key size to ensure their security well into the future. Because of this, most providers encourage 2048-bit keys on all certificates whether they are EV or not.
