Keytool is a key and certificate management utility. It allows users to administer their own public/private key pairs and associated certificates for use in self-authentication keytool - Key and Certificate Management Tool Online. You can not convert it to a certificate. You must generate a certificate by sending it to a certificate authority or creating a self-signed certificate. Please select a certificate to convert. Please select a private key. You must have a private key file that matches with your certificate to make a.pfx file. How to generate a key file out of a.cert? Ask Question Asked 7 years, 7 months ago. No, there is no way to create a private key when you only have the public key. The entire encryption systems rests on idea that you cannot do this.

- Jun 05, 2012 This video describe how to generate an RSA private key and certification x509 to be used in Wakansa, to secure communication. Steps by Steps How to convert ssl certificate crt and key file into.
- Secure and easy Certificate Signing Request generation for your SSL certificates. Complete this form to generate a new CSR and private key.
- The public key will be signed by a Certification Authority, and the result is a digital certificate (which can be in a CRT file) My point is: if you have a CRT file (aka certificate), it means a key pair was already generated and signed by a Certification Authority. There's no way to generate a new key from it (because it already has a key).
Common Name (Server Name) The fully qualified domain name that clients will use to reach your server. For example, to secure https://www.example.com, your common name must be www.example.com or *.example.com for a wildcard certificate. Although less common, you may also enter the public IP address of your server. Department (optional) You can leave this field blank. This is the department within your organization that you want to appear on the certificate. It will be listed in the certificate's subject as Organizational Unit, or 'OU'. Common examples: Web Administration, Web Security, or Marketing City The city where your organization is legally located. State or Province The state or province where your organization is legally located. Country We guessed your country based on your IP address, but if we guessed wrong, please choose the correct country. If your country does not appear in this list, there is a chance we cannot issue certificates to organizations in your country. Organization name The exact legal name of your organization, (e.g., DigiCert, Inc.) If you do not have a legal registered organization name, you should enter your own full name here. Key RSA Key sizes smaller than 2048 are considered unsecure. Now just copy and paste this command into a terminal session on your server. Your CSR will be written to ###FILE###.csr. |
After you've created a Certificate Signing Request (CSR) and ordered your certificate, you still need to install the SSL certificate on your server.

Where do I paste this command?
You can run this command wherever you have OpenSSL available—most likely on your server, but you can also run it on your own computer since macOS comes with OpenSSL installed. Just make sure you keep track of your private key file after you create your CSR; you'll need that private key to install your certificate.
What happens when I run this command?
OpenSSL creates both your private key and your certificate signing request, and saves them to two files: your_common_name.key, and your_common_name.csr. You can then copy the contents of the CSR file and paste it into the CSR text box in our order form.
What kind of certificate should I buy?
If you want an SSL certificate for Apache, your best options are Standard certificates and Wildcard certificates.
Online RSA Key Generator. Key Size 1024 bit. 512 bit; 1024 bit; 2048 bit; 4096 bit Generate New Keys Async. RSA Encryption Test. Text to encrypt: Encrypt / Decrypt. Public private key generator rsa. To generate public (e,n) key from the private key using openssl you can use the following command: openssl rsa -in private.pem -out public.pem -pubout To dissect the contents of the private.pem private RSA key generated by the openssl command above run the following (output truncated to labels here).
A DigiCert Wildcard can protect all server names on your domain (e.g., *.example.com,). Our unlimited server license lets you protect all your servers for just one price. Many of our customers save thousands of dollars per year by using a DigiCert Wildcard certificate.

What If I Need Subject Alternative Names?
Multi-Domain (SAN) certificates allow you to assign multiple host names—known as Subject Alternative Names or SANs—in one certificate.
Using OpenSSL to Add Subject Alternative Names to a CSR is a complicated task. Our advice is to skip the hassle, use your most important server name as the Common Name in the CSR, and then specify the other names during the order process. Our Multi-Domain (SAN) certificate ordering process allows you to specify all the names you need without making you include them in the CSR.
You can also use OpenSSL to create a certificate request for your code signing certificate.
