Issue #5600 has been updated by Kazuki Yamaguchi.

Status changed from Assigned to Closed

r55098 (openssl: add OpenSSL::PKey::EC#private? and #public?, 2016-05-21) added OpenSSL::PKey::EC#private?. The code should work now.

Please see also #6567.

----------------------------------------
Bug #5600: OpenSSL::X509::Request can't sign() an OpenSSL::PKey::EC
https://bugs.ruby-lang.org/issues/5600#change-59238

* Author: Steve Caligo
* Status: Closed
* Priority: Normal
* Assignee: openssl
* ruby -v: ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-linux]
* Backport: 
----------------------------------------
Unlike the PKey::DSA and PKey::RSA classes, PKey::EC provides a private_key?() rather than private?() method and is thus incompatible with the other OpenSSL classes that rely on them, i.e. it makes impossible to generate a certificate signing request:

key = OpenSSL::PKey::EC.new('secp521r1')
key.generate_key

req = OpenSSL::X509::Request.new
req.public_key = key
req.subject = OpenSSL::X509::Name.parse('CN=whatever')
req.sign(key, OpenSSL::Digest::SHA384.new)


which produces the error:

in `sign': undefined method `private?' for #<OpenSSL::PKey::EC:0x000000021b4980> (NoMethodError)


ossl_pkey_ec.c should either:
- rb_define_method() the missing private? and public? methods
- rename public_key? to public? and private_key? to private?

Judging by the source code, this should be present in branch 1.8 as well.
