I am able to create RSA/DSA keys. How to create AES128 encrypted key with openssl. This command uses AES 128 only to protect the RSA key pair with a passphrase, just in case an unauthorized person can get the key file. When your Apache server starts up, it must decrypt the key in memory to use it. To create a new Private Key without a passphrase. # openssl genrsa -out www.example.com.key 4096 To create a new password protected Private Key (Remember the passphrase) # openssl genrsa -des3 -out www.example.com.key.password 4096 To remove the passphrase from the password protected Private Key. $ openssl req -new -key /path/to/wwwservercom.key -out /path/to/wwwservercom.csr. This will fire up OpenSSL, instruct it to generate a certificate signing request, and let it know to use a key we are going to specify – the one we just created, in fact.
The PuTTYgen program is part of PuTTY, an open source networking client for the Windows platform.
Public private key pair generation. The key is available via the public accessible directory.
To download PuTTY or PuTTYgen, go to http://www.putty.org/ and click the You can download PuTTY here link.
As the key is being generated, move the mouse around the blank area as directed.
Note:
While a passphrase is not required, you should specify one as a security measure to protect the private key from unauthorized use. When you specify a passphrase, a user must enter the passphrase every time the private key is used.
.ppk
(PuTTY private key).Note:
The.ppk
file extension indicates that the private key is in PuTTY's proprietary format. You must use a key of this format when using PuTTY as your SSH client. It cannot be used with other SSH client tools. Refer to the PuTTY documentation to convert a private key in this format to a different format. Make sure you select all the characters, not just the ones you can see in the narrow window. If a scroll bar is next to the characters, you aren't seeing all the characters.
.pub
extension to indicate that the file contains a public key.ssh
utility on Linux), export the private key:.ppk
format, using an extension such as .openssh
to indicate the file's content.
