Class GenerateKeyPair

java.lang.Object

examples.GenerateKeyPair

public class GenerateKeyPair
extends java.lang.Object

This is a simple demo of how to generate public key pairs for use with ssh2. A file containing some definitions of the key must supplied as argument.

Usage: java -cp examples.jar examples.GenerateKeyPair definition_file

The definition file is a standard Java property file which should contain the following properties:

format

Format of keyfile. Valid values are openssh and sshinc. The default value is openssh.

algorithm

Which algorithm to generate a key for. Valid valus are RSA and DSA. The default value is RSA.

bits

Number of bits in key. The default value is 1024.

password

Password used to encrypt the private key

subject

String identifying the owner of the key

comment

Key comment

keyfile

Base-name of files to save keys in. The private file will be stored in keyfile and the public key in keyfile.pub
