Hello

On Windows, I'm using Crypt::PK::RSA to generate key pairs like this:

use Crypt::PK::RSA;
my $pk = Crypt::PK::RSA->new();
$pk->generate_key(256, 65537);
my $private_pem = $pk->export_key_pem('private');
my $public_pem = $pk->export_key_pem('public');

[download]

Private key format is fine. Public key is generated like this:

-----BEGIN RSA PUBLIC KEY-----
...
-----END RSA PUBLIC KEY-----

[download]

Since I need to add this key to authorized_keys files it needs to be in a ssh-rsa format.

Can easly be done using ssh-keygen to convert:

$ ssh-keygen -y -f privatekey > publickey

[download]

I found this thread explaining the process and having several solutions none perl based.

And all end up being dependent on ssh-keygen or open-ssl both not natively available on Windows

Does anyone know how to do this only in perl or if it is even possible?
