如果仍然有人在使用Ruby签名和加密配置文件时遇到问题，下面的答案将是有用的。

Incase if still anybody is having issues with signing and encrypting the profile with Ruby, following answer would be useful.

OpenSSL 模块可在Ruby和 Plist gem。

I have used OpenSSL module available in Ruby and Plist gem.

考虑密码限制

passcode_payload ={
              'PayloadUUID' => 'RANDOM_STRING_UUID',
              'PayloadOrganization' => 'PayloadOrganization',
              'PayloadVersion' => 1,
              'PayloadIdentifier' => 'com.test.PayloadIdentifier',
              'PayloadType' => 'Configuration',
              'PayloadDisplayName' => 'PayloadDisplayName',
              'PayloadRemovalDisallowed' => false
            }
  passcode_payload_content = {
              'PayloadDescription' => 'PayloadDescription',
              'PayloadDisplayName' => 'PayloadDisplayName',
              'PayloadIdentifier' => 'PayloadIdentifier',
              'PayloadOrganization' => 'PayloadOrganization',
              'PayloadType' => 'com.apple.mobiledevice.passwordpolicy',
              'PayloadUUID' => "RANDOM_STRING_UUID",
              'PayloadVersion' => 1,
              'allowSimple' => true,
              'forcePIN' => true
              'maxPINAgeInDays' => 20,
              'minComplexChars' => 1,
              'minLength' => 4,
              'requireAlphanumeric' => true
            }

通常，对于普通个人资料， passcode_payload_content 进入 passcode_payload ['PayloadContent'] 作为字典数组。

Usually for a normal profile the passcode_payload_content goes into the passcode_payload['PayloadContent'] as array of dictionaries.

passcode_payload ['PayloadContent'] = [passcode_payload_content]

但对于加密的个人资料， PayloadContent 并且应根据 EncryptedPayloadContent 。 html＃// apple_ref / doc / uid / TP40010206-CH1-SW52rel =nofollow>配置个人资料键参考文档。

But for an encrypted profile, PayloadContent should be removed and EncryptedPayloadContent should be used as per the configuration profile key reference document.

，

要加密配置文件，请执行以下操作：

删除 PayloadContent $

请注意，此plist中的***对象是数组，而不是
字典。

CMS将串行化plist加密为包络数据。
以DER格式序列化加密的数据。

将序列化数据设置为
，作为配置文件中Data Plist项的值，使用键
EncryptedPayloadContent

To encrypt a profile do the following:

Remove the PayloadContent array and serialize it as a proper plist.

Note that the top-level object in this plist is an array, not a dictionary.

CMS-encrypt the serialized plist as enveloped data. Serialize the encrypted data in DER format.

Set the serialized data as the value of as a Data plist item in the profile, using the key EncryptedPayloadContent

由于plist中的***对象应该是一个数组

Since top level object in the plist should be an array

passcode_payload_content_array = [passcode_payload_content]

序列化到正确的plist

Serializing to proper plist

to_be_encrypted_plist = passcode_payload_content_array.to_plist

加密凭证负载内容，

device_certificate = OpenSSL::X509::Certificate.new File.read('deviceIdentityCertificate.pem')
encrypted_payload = OpenSSL::PKCS7.encrypt([device_certificate],to_be_encrypted_plist, OpenSSL::Cipher::Cipher::new("des-ede3-cbc"),OpenSSL::PKCS7::BINARY)

添加加密的有效内容到原始有效负载的格式

Add encrypted payload content to the original payload in der format

passcode_payload['EncryptedPayloadContent'] = StringIO.new(encrypted_payload.to_der)

**

**

signed_passcode_profile = OpenSSL::PKCS7.sign(SSL_CERTIFICATE, SSL_KEY, passcode_payload.to_plist, [], OpenSSL::PKCS7::BINARY)

最后，可以使用

send_data signed_passcode_profile.to_der, :type => "application/x-apple-aspen-config" 

发送有效载荷。
