title: Ruby OpenSSL RSA decryption failing due to padding check failed
body: <p>I'm trying to replicate the following python code in ruby.  The python code works fine, the ruby code fails due to "padding check failed".  I can encrypt a string and decrypt it with the private key in Ruby, but the encrypted data I need to work with is being retrieved from elsewhere.  I'm unsure of the library and even language used to encrypt it, but the Python code works.</p>
  
  <p>Working Python code:</p>
  
  <pre><code>def decrypt_secret(encrypted_base64, private_key):
    key = RSA.importKey(open(private_key, "r").read())
    pkey = PKCS1_OAEP.new(key, hashAlgo=SHA256)
    encrypted_blob = base64.urlsafe_b64decode(encrypted_base64)
    decrypted_string = pkey.decrypt(encrypted_blob)
    return decrypted_string
  </code></pre>
  
  <p>Ruby Code fails "padding check failed"</p>
  
  <pre><code>def decrypt_secret(encrypted_base64, private_key)
    key = File.read(private_key)
    pkey = OpenSSL::PKey::RSA.new(key)
    encrypted_blob = Base64.urlsafe_decode64(encrypted_base64)
    decrypted_string = pkey.private_decrypt(encrypted_blob, OpenSSL::PKey::RSA::PKCS1_OAEP_PADDING)
    return decrypted_string
  end 
  </code></pre>
