sshkey
|
||
|
|
======
|
||
|
|
|
||
|
|
Generate private and public SSH keys (RSA and DSA supported) using pure Ruby.
|
||
|
|
|
||
|
|
gem install sshkey
|
||
|
|
|
||
|
|
Tested on the following Rubies: MRI 1.8.7, 1.9.2, 1.9.3, REE. Ruby must be compiled with OpenSSL support.

Usage
|
||
|
|
-----
|
||
|
|
|
||
|
|
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`:
|
||
|
|
|
||
|
|
``` ruby
|
||
|
|
k = SSHKey.generate
|
||
|
|
|
||
|
|
k = SSHKey.generate(:type => "DSA", :bits => 1024, :comment => "foo@bar.com")
|
||
|
|
```
|
||
|
|
|
||
|
|
Return an SSHKey object from an existing RSA or DSA private key (provided as a string)
|
||
|
|
|
||
|
|
``` ruby
|
||
|
|
k = SSHKey.new(File.read("~/.ssh/id_rsa"), :comment => "foo@bar.com")
|
||
|
|
```
|
||
|
|
|
||
|
|
Both of these will return an SSHKey object with the following methods:
|
||
|
|
|
||
|
|
``` ruby
|
||
|
|
# Returns an OpenSSL::PKey::RSA or OpenSSL::PKey::DSA key object

|

|
||
|
|
k.key_object
|
||
|
|
# => -----BEGIN RSA PRIVATE KEY-----\nMIIEowI...
|
||
|
|
|
||
|
|
# Returns the Private Key as a string
|
||
|
|
k.private_key
|
||
|
|
# => "-----BEGIN RSA PRIVATE KEY-----\nMIIEowI..."
|
||
|
|
|
||
|
|
# Returns the Public Key as a string
|
||
|
|
k.public_key
|
||
|
|
# => "-----BEGIN RSA PUBLIC KEY-----\nMIIBCg..."
|
||
|
|
|
||
|
|
# Returns the SSH Public Key as a string
|
||
|
|
k.ssh_public_key
|
||
|
|
# => "ssh-rsa AAAAB3NzaC1yc2EA...."
|
||
|
|
|
||
|
|
# Returns the comment as a string
|
||
|
|
k.comment
|
||
|
|
# => "foo@bar.com"
|
||
|
|
|
||
|
|
# Returns the MD5 fingerprint as a string
|
||
|
|
k.md5_fingerprint
|
||
|
|
# => "2a:89:84:c9:29:05:d1:f8:49:79:1c:ba:73:99:eb:af"
|
||
|
|
|
||
|
|
# Returns the SHA1 fingerprint as a string
|
||
|
|
k.sha1_fingerprint
|
||
|
|
# => "e4:f9:79:f2:fe:d6:be:2d:ef:2e:c2:fa:aa:f8:b0:17:34:fe:0d:c0"
|
||
|
|
|
||
|
|
# Validates SSH Public Key
|
||
|
|
SSHKey.valid_ssh_public_key? "ssh-rsa AAAAB3NzaC1yc2EA...."
|
||
|
|
# => true
|
||
|
|
```
