Split ssh public key and comment

[grv87]

Could you add this feature: split ssh public key to key itself and the comment, so they could be processed separately?

@grv87 I'd recommend setting the comment to nil before calling ssh_public_key, that way you can get at the SSH public key without the comment.

key = SSHKey.generate(comment: "bensie")
# => #<SSHKey:0x007fc989a3fed0 @passphrase=nil, @comment="bensie", @directives=[], @key_object=#<OpenSSL::PKey::RSA:0x007fc989a3fd40>, @type="rsa">
key.comment = nil
# => nil
key.ssh_public_key
# => "ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDMa72cykdsZ0yyqeS+Spm/0GimN2uJ0AWY46bpEmAo2TKT3bmionSLVE1kqbTrLfeTrXsbrjnhOgFS3A3BshI4/9i4JeQ5OyqJiotG+S5qQhQsSSC8olwIes2/34cV70aPQa7PNdlfAv1H/7pUVrNu4lJU7BI1NevWpmWG7PG9cu9ifRcdCy7O3CMHiB1HnqCZ6SgSLyedopdCpR8x3fhYWxM6ca+LrUANePMbfC7yPUO4G5mSMGUXmFYCDyIlYQXR3KCzBxHN8y4H1WXMxlSdHFw/qjQtX1rqvtk0yOer/H32xInq/LkO7YtrQhqplPIainHxbnSjcJG8KNmb4brV"

@bensie, I need to parse existing public key. The same way as valid_ssh_public_key?, but to get the key and the comment separately.

I've ended using split(' ')[0..1] and [2] respectively.

Yeah then I think the way you're doing it is your best bet.
