Demonstrates how to load the public and private keys produced by ssh-keygen.

Chilkat Ruby Downloads install from rubygems.org gem install chilkat or download... Ruby Library for Windows, MacOS, Linux, Alpine Linux

require 'chilkat'

# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# We first generate a key like this:

#     ssh-keygen -f stg.chilkat.id
#     Generating public/private rsa key pair.
#     Enter passphrase (empty for no passphrase):
#     Enter same passphrase again:
#     Your identification has been saved in stg.chilkat.id.
#     Your public key has been saved in stg.chilkat.id.pub.
#     The key fingerprint is:
#     SHA256:hkbgexkspxYTa8rYUxouRU8Gi7lbbsT6dSLX+JlStKk me@example02240
#     The key's randomart image is:
#     +---[RSA 2048]----+
#     |  o.=            |
#     | + * =           |
#     |o + X =          |
#     | O * O.+         |
#     |+ @ +.=oS        |
#     | A o =+.         |
#     |o + =oo          |
#     | o +E+ o         |
#     |  .  .+          |
#     +----[SHA256]-----+

# 

# The public key (generated to the file stg.chilkat.id.pub) contains this:
# ssh-rsa AAAAB3NzaC1yc2EAAAADAQABA.. FDt+dKJEkhw8I7LpEi17diB9 me@example02240

# First let's load the public key:
pubkey = Chilkat::CkSshKey.new()

success = pubkey.FromOpenSshPublicKey(pubkey.loadText("qa_data/sshKeys/ssh-keygen/stg.chilkat.id.pub"))
if (success == false)
    print pubkey.lastErrorText() + "\n";
    exit
end

print pubkey.lastErrorText() + "\n";
print "Successfully loaded the public key." + "\n";

# Now try the private key, which contains this:

# -----BEGIN OPENSSH PRIVATE KEY-----
