Feature #4424: [ext/openssl] Allow public/private key creation from arbit=
rary data
http://redmine.ruby-lang.org/issues/show/4424

Author: Martin Bosslet
Status: Open, Priority: Normal
Category: ext, Target version: 1.9.3

There is a public funtion in PKey that allowed to read arbitrary
private keys from a file regardless of the actual key type, but it
was not exposed in Ruby, only in C. =

In Ruby, the only way to instantiate public/private keys is by =

calling initialize on the correct PKey subclass, implying that =

you need to know what kind of key you're actually dealing with. =

There are situations where the key type is not known in advance, =

e.g. if a certificate SubjectPublicKeyInfo shall be turned into =

a public key. In that case you only know that you're dealing with
a public key, but not necessarily with what kind of key. In =

situations like these it would come in handy to have methods that
create a PKey instance regardless of the underlying data.

The attached patch provides this by adding two module functions to =

PKey, read_public and read_private. They allow reading generic =

public/private keys from a String or a File, optionally providing
a password in the case of encrypted PEM encodings. RDoc has also
been supplemented.

Please note that the included tests partly rely on the patches =

proposed in

http://redmine.ruby-lang.org/issues/show/4421,
http://redmine.ruby-lang.org/issues/show/4422 and
http://redmine.ruby-lang.org/issues/show/4423

If those were applied, the combination with this patch would =

provide consistent behavior among all three public key systems
supported in Ruby.

Regards,
Martin
