More certificate icons

[Cacsjep]

Before submitting a new icon request, please confirm the following:

• I have searched all issues to make sure there isn't a request for this icon.
• I have searched the current library to make sure the icon doesn't already exist.
• I understand that brand icons are no longer being added and I can use SimpleIcons for my brand icon needs.
• I only intend to request a single icon (or a few near-identical ones) in this issue.

What would you use this icon for?

I would use it for my PKI tool.

• Certificate Generate
• Certificate Remove
• Certificate Plus
• Certificate Edit
• Certificate Private Key
• Certificate Download
• Certificate Select
• Certificate Search

big thanks, would love to see such one =)

Give us an example of what this icon might look like.

Similar to account icons but for certifcate
