IPython: How to wipe IPython's history selectively & securely?

Question

I have been learning how to use the paramiko package only to discover that all I stored passwords in plain text in IPython\'s %hist. Not so good.

Answer 1

Combining @Ovidiu Ghinet's answer with @Matt's accepted answer:

sqlite $(ipython locate)/profile_*/*.sqlite || sqlite3 $(ipython locate)/profile_*/*.sqlite

Then from within sqlite console:

delete from history where source like '%password%';
select * from history; /* confirm that no passwords left        */
.quit                  /* forgot how to exit sqlite console? ;) */
