Openssl Generate Private Key Pem Format
How do I convert my Amazon Elastic Compute Cloud (Amazon EC2) Privacy Enhanced Mail (.pem) file to a PuTTY Private Key (.ppk) file? Or, convert a .ppk file to a .pem file?
PKCS12 - A Microsoft private standard that was later defined in an RFC that provides enhanced security versus the plain-text PEM format. This can contain private key material. Its used preferentially by Windows systems, and can be freely converted to PEM format through use of openssl. DER - The parent format of PEM. This means that you can simple copy and paste the content of a pem file to another document and back. Following is a sample PEM file containing a private key and a certificate, please note that real certificates are a couple of times larger, containing much more random text between the 'BEGIN' and 'END' headers. OpenSSL in Linux is the easiest way to decrypt an encrypted private key. Use the following command to decrypt an encrypted RSA key: Make sure to replace the “server.key.secure” with the filename of your encrypted key, and “server.key” with the file name that you want for your encrypted output key file. Assuming you have the SSH private key idrsa, you can extract the public key from it like so. Openssl rsa -in idrsa -pubout -out idrsa.pub.pem I realize the OP asked about converting a public key, so this doesn't quite answer the question, however I thought it would be useful to some anyway. Generating the Public Key - Windows 1. At the command prompt, type the following: openssl rsa -in rsa.private -out rsa.public -pubout -outform PEM 2. The public key is saved in a file named rsa.public located in the same folder. Generating the Private Key - Linux 1. Open the Terminal. Navigate to the folder with the ListManager directory.
Jun 19, 2015 The commands below demonstrate examples of how to create a.pfx/.p12 file in the command line using OpenSSL: PEM (.pem,.crt,.cer) to PFX openssl pkcs12 -export -out certificate.pfx -inkey privateKey.key -in certificate.crt -certfile more.crt. And you can have private key in PKCS#1 or PKCS#8 format. The extensions (.der,.pem,.key,.cer etc.) are only for convenience to easily identify what is inside (well, we wish to trust that the content corresponds to the extension used). Command openssl genrsa -out rsaprivkey.pem 1024 generated private key in PKCS#1 format and PEM encoding.
Short Description
PuTTY doesn't natively support the private key format (.pem) generated by Amazon EC2. You must convert your private key into a .ppk file before you can connect to your instance using PuTTY. You can use the PuTTYgen tool for this conversion. This tool, available for both Windows and Unix operating system, can convert keys.
Resolution
Windows - install PuTTYgen
Most Windows operating systems have PuTTY installed. If your system doesn't, download and install PuTTYgen.
Windows - convert a .pem file to a .ppk file
Start PuTTYgen, and then convert the .pem file to a .ppk file. For detailed steps, see Convert Your Private Key Using PuTTYgen.
Windows - convert a .ppk file to a .pem file
- Start PuTTYgen. For Actions, choose Load, and then navigate to your .ppk file.
- Choose the .ppk file, and then choose Open.
- (Optional) For Key passphrase, enter a passphrase. For Confirm passphrase, re-enter your passphrase.
Note: Although a passphrase isn't required, you should specify one as a security measure to protect the private key from unauthorized use. Using a passphrase makes automation difficult, because human intervention is needed to log in to an instance or to copy files to an instance. - From the menu at the top of the PuTTY Key Generator, choose Conversions, Export OpenSSH Key.
Note: If you didn't enter a passphrase, you receive a PuTTYgen warning. Choose Yes. - Name the file and add the .pem extension.
- Choose Save.
Unix or Linux - install PuTTY
Install PuTTY, if it's not already on your system.
Important: A PuTTY package is provided by the Extra Packages for Enterprise Linux (EPEL) repository. You must enable the EPEL repository before you install PuTTY.
To install PuTTY, run one of the following commands:
RPM-based
Dpkg-based
Unix or Linux - convert a .pem file to a .ppk file
On the instance shell, run the puttygen command to convert your .pem file to a .ppk file:
Unix or Linux - convert a .ppk file to a .pem file
Run the puttygen command to convert a .ppk file into a .pem file:
Mac product key finder.
