Paste Private Key From Clipboard Step 1 Solution Assessment

Problem Statement

Users need to restore a browser posting identity by pasting private key material from the clipboard without sending it to the server. Source: thread-20260826035057-1ac5dd17, submitted 2026-08-26T03:50:57Z.

Option A: Add local-only private key paste/import on the account page

Pros:

• Directly supports the submitted workflow.

• Keeps private key material client-side.

• Fits the existing browser-held identity model.

Cons:

• Needs careful validation and failure messages.

• Raw private key text is sensitive and easy to mishandle.

Option B: Add an export/import identity backup bundle

Pros:

• Cleaner long-term migration experience.

• Can include public metadata and versioning.

Cons:

• Does not fully solve users who already copied only the private key.

• Larger format and compatibility decision.

Option C: Add server-assisted key recovery

Pros:

• Potentially easier for nontechnical users.

Cons:

• Conflicts with the no-server-private-key model.

• High security and trust risk.

Recommendation

Recommend Option A.

Brief justification:

• The immediate request is clipboard restore, and local-only import preserves the existing private-key security boundary.
