Ruby Openssl Generate Rsa Key
Feb 11, 2019 When generating a new keypair the default key type is 2048-bit RSA, but you can supply the type (RSA or DSA) and bits in the options. You can also (optionally) supply a comment or passphrase. K = SSHKey.generate k = SSHKey.generate( type: ' DSA ', bits: 1024, comment: ' foo@bar.com ', passphrase: ' foobar ' ). The opensslrsaprivatekey resource has the following properties. Force Ruby Type: true, false Default Value: false Force creation of the key even if the same key already exists on the node. Group Ruby Type. String, Integer The group ownership applied to all files created by the resource. Generate the CSR code and Private key for your certificate by running this command: openssl req -new -newkey rsa:2048 -nodes -keyout server.key -out servercsr.txt. Note: server.key and servercsr.txt are the Private key and the CSR code files. Feel free to use any file names, as long as you keep the.key and.txt extensions.
To perform the following actions for Windows or Linux, you must have OpenSSL installed on your system.
Generating the Private Key -- Windows
In Windows:
1. Open the Command Prompt (Start > Programs > Accessories > Command Prompt).
2. Navigate to the following folder:
C:Program FilesListManagertclwebbincerts
3. Type the following: Openssh key format.
openssl genrsa -out rsa.private 1024
4. Press ENTER. The private key is generated and saved in a file named 'rsa.private' located in the same folder.

NOTE The number '1024' in the above command indicates the size of the private key. You can choose one of five sizes: 512, 758, 1024, 1536 or 2048 (these numbers represent bits). The larger sizes offer greater security, but this is offset by a penalty in CPU performance. We recommend the best practice size of 1024.
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. Press ENTER. 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.
2. Navigate to the folder with the ListManager directory.
3. Type the following:
openssl genrsa -out rsa.private 1024
4. Press ENTER. The private key is generated and saved in a file named 'rsa.private' located in the same folder.
Generating the Public Key -- Linux
1. Open the Terminal.
2. Type the following:
openssl rsa -in rsa.private -out rsa.public -pubout -outform PEM

2. Press ENTER. The public key is saved in a file named rsa.public located in the same folder.
