Further reading See this question: 2011-07-12, Thanks for contributing an answer to Information Security Stack Exchange!. It is used to encrypt outgoing messages and decrypt incoming messages. For your convenience, below is a description of each certificate type: Multiple domain certificates are used for numerous domains and subdomains. Sometimes it might get confusing, since more often than not Certificate Authorities name certificate types differently even though they are the same thing.

Here's an example in Ruby: This example provided as an edit by. Download and install the runtimes. You may need them for development. But here's the catch: user-oriented tools such a openssl command line will only create certificates either a self-signed using a private key, or b by signing a request.

Use the drop-down menu to select your servers. Since you generate a self-signed certificate for testing purpose only it does not matter what information you enter. Note: You cannot use the following characters in the Organization Name or Organizational Unit fields: ~! It can be tricky to create one that can be consumed by the largest selection of clients, like browsers and command line tools. First of all, what you are attempting to do will not work. You can do that in one command: openssl req -x509 -newkey rsa:4096 -keyout key. When you produce a public key this way, it is extracted from the private key file, not calculated. The problem I'm having is getting the public key out of the certificate in the format I need.

Also as mentioned in below answers you can derive a public key from a private key as well. Verify a Private Key Use this command to check that a private key domain. It is standard to either use. It allows anyone to use it for encrypting messages to be sent to the user, as well as for decrypting messages received from the user. The -x509 option tells req to create a self-signed cerificate. You can omit that part of the file name to have a private key created in the very same directory where you run the command. Note that a certificate signing request always has a file name ending in.

This is probably not the site you are looking for! The key's algorithm identifier is rsaEncryption 1. As far as whether or not this can be done: Certificates have to be signed by someone. It generates a format that Github takes! Note: Iguana offers support for x509 compatible certificates in pem format, certificates must not be password protected. In consists of a public part - the certificate, and a private key. Upon completion of this process, you will be returned to a command prompt. So the complete solution is to become your own authority.

You can optionally specify some defaults. This is because browsers use a predefined list of trust anchors to validate server certificates. Here we always use openssl pkey, openssl genpkey, and openssl pkcs8, regardless of the type of key. The algorithm identifier will be id-ecPublicKey 1. You can submit a comma-separated list. A public key is the one that is released to the public.

You can check the for more information. They could just as easily be assigned in reverse. When you are done with the generator, you can return to the Cloud Control Panel by clicking any of the terms in the top navigation or by going to and selecting Rackspace Cloud from the drop-down product menu in the top navigation bar. Create and verify your pass phrase here — note that the characters you are typing will not be displayed. Names Optional Additional domains that you want to add to the request. To every one using rsa and openssl and wanting to encrypt a large file like 5 Kbyte. Direct usages of some certificate-aware library can do the trick.

It is not uncommon for popular browsers to distrust all certificates issued by a single Certificate Authority. However, there is nothing magical about self signatures in certificates. The -key option specifies an existing private key domain. Just remember that this information will be visible to anyone having access to your generated certificate. So I have been doing my research and haven't found anything specific enough to my problem.
