Question

我试图在rails上使用mail-gpg ruby gem来了解pgp加密，虽然我使它工作并且加密和解密都工作，但他们并不能完全满足我的解密pgp消息显示我不想发送的信息也正在加密。

代码：

  class EncryptMailer < ApplicationMailer
    def encrypted_mail user
        mail to: "#{user.email}", subject: 'Hopefully this is encrypted', content_type: 'text/plain', gpg: { encrypt: true, keys: { "#{user.email}" => user.pgp_key}}
    end
  end

邮件视图：

可见，加密的阻止消息最终会有一堆我不想要的额外信息。有没有办法只加密电子邮件的正文？或者我最好只加密邮件程序本身以外的邮件程序视图？

更新

在更好地了解gem的源代码之后，似乎这是作者的慎重选择，但是实现一个选项以使加密仅占用主体是很容易的。我已经提交了请求获取拉取请求权限的问题，但万一我从未批准过这样做。

在gem的源代码中（你可以找到here）转到encrypted_part.rb文件并在加密变量分配

clean = options[:clean] clean ? cleartext_mail = cleartext_mail.body : cleartext_mail

那就是它！您现在可以像这样调用gpg调用中的 clean 选项。

def encrypted_mail user mail to: "#{user.email}", subject: 'Hopefully this is encrypted', content_type: 'text/plain', gpg: { encrypt: true, clean: true keys: { "#{user.email}" => user.pgp_key} end
