I have reset my OS X Lion Keychain by mistake. Is there any way to restore the Keychain content from Trash?

I'm asking this because I do find a Keychain Access icon in the Trash Bin. It would be a big help since the reset seems to have wiped out all the certificates.

Well, if you have a keychain in your Trash, just right-click it and put it back. Or move it to ~/Library/Keychains. – slhck Oct 15 '12 at 11:51
I did a search with Finder. There doesn't seem to have any directory named Library in my OSX 10.7.5.. – Stanley Oct 16 '12 at 3:15

The Library folder where your keychains are stored is hidden by default.

First, quit Keychain

Open Finder and press Shift Cmd G, then enter ~/Library/Keychains. Here, rename the existing default file, and drag your original file back from the Trash.

Restart Keychain Access and you should see your old one restored.

Thanks for the answer. I have exported the keys/certificates from my home computer and imported to the office computer where the Keychain was lost. But your solution should also work since I can now find the Library folder... – Stanley Oct 16 '12 at 20:16

Here's a way to restore passwords lost back into the Keychain content.

Keychain Access will lose saved passwords often when there's a stored password in Keychain desired to be deleted; and once the item is highlighted and Edit > Delete is clicked, and, instead of just clicking the 'delete file' button, the 'delete file and all references' button gets clicked.

  1. Open Keychain Access (located in the 'Utilities' folder)
  2. Go to the "Keychain Access" menu > select "Preferences"
  3. Click the "First Aid" tab
  4. Make sure the "Synchronize login keychain password" box is checked.
  5. Close the Preferences window.
  6. Go to the "Keychain Access" menu and select "Keychain First Aid"
  7. Enter the administrator's username & password
  8. Click the "Repair" button.
  9. Click the 'Verify' button.

Now go ahead and restore all the missing, previously saved passwords back into Keychain Access:
1.) Quit the Keychain Access app.
2.) Goto ~/Library/Keychain/login.keychain file, then highlight it
3.) Enter Time Machine
4.) Goto a previous date's restore-point wherein Keychain Access held all your passwords correctly
5.) Click on 'Restore this file' —> replace the unwanted current version of this file;
6.) Goto ~/Library/Preferences/ file, then highlight it
7.) Once again, enter Time Machine
8.) Select that very same previous restore-point-date that was used to restore the login.keychain file
9.) Click on 'Restore this file' —> replace the unwanted current version of this file.

Reopen the Keychain Access app and assure that all inadvertently deleted passwords were indeed restored,
and then
Go to the "Keychain Access" menu and select "Keychain First Aid"
Enter the account's username & password
Click the "Repair" button.

Close the Keychain Access app.
