RSA (Rivest–Shamir–Adleman) is one of the first public-key cryptosystems and is widely used for secure data transmission. In such a cryptosystem, the encryption key is public and distinct from the decryption key which is kept secret (private). Generate an RSA private key: C:Opensslbinopenssl.exe genrsa -out Key Filename Key Size Where: Key Filename is the desired filename for the private key file. Key Size is the desired key length of either 1024, 2048, or 4096. For example, type: C:Opensslbinopenssl.exe genrsa -out mykey.key 2048.
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:
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.
