公開鍵を使用して OpenSSL::PKey::RSA を初期化しようとしていますが、機能していません。

キーペアは次のとおりです。

-----BEGIN RSA PRIVATE KEY-----

物事が失敗する原因となる public_key の何が問題になっていますか?

require 'openssl'
require 'base64'

public_key = "MIIBCgKCAQEA20O377QEiZvPsj14LKl2xO23iirJB5WDTVjeab1cIOJu1vbV+Pdwl1Bov8m896ZG4K0S/qvfJcdHLovr2WJ+o2maK1XZCNy8lA" +

It looks like what you've got there should work only the public key itself isn't valid. Maybe you mangled them at some point by adding or removing an extra character by accident. You can test this key out and should see it work out 

public_key = "-----BEGIN RSA PUBLIC KEY-----\nMIIBCgKCAQEAoxi2V0bSKqAqUtoQHxWkOPnErCS541r6/MOSHmKOd6VSNHoBbnas\nZRQSDUTbffB6C++DbmBCOHmvzYORD0ZWYgyMcgbYJD48Z2fe0nm+WMYN5u8DPnTP\nvf8b/rJBxGF0dsaoFAWlB81tTnKFCxAbCSgfmQt+Vd4qupGZ5gGu9uoKlaPjmYuA\nIxIjUMcu3dov7PQ+PZIvdkM0fiz8YIl8zo+iWWyI2s6/XLoZJ4bYs2YJHZDf6biU\nsZhs8xqh/F6qlcRt3Ta25KMa0TB9zE3HHmqA/EJHFubWFRCrQqpboB0+nwCbmZUl\nhaxA79FRvYtORvFAoncoFD4tq3rGXcUQQwIDAQAB\n-----END RSA PUBLIC KEY-----\n"

OpenSSL::PKey::RSA.new(public_key)

I generated my key by first running the linux command for generating an openSSH key pair

$  ssh-keygen -t rsa -b 1024

Then I converted OpenSSH style public key to an OpenSSL style key (PEM format), storing it in a file called 'pem'. 

$  ssh-keygen -f testing_rsa.pub  -e -m pem > pem
