My first big project was to hash / encrypt customer passwords (this was 13 years ago). Worked for an ISP. Half way through the rollout customer support started reporting an increase in connection issue tickets. Clients failing to authenticate.

Turns out I'd string trimmed binary strings thus truncating any with NUL bytes. 50k users affected including their RADIUS records (which were used to authenticate their ADSL connection).

I will always be thankful to the senior engineer I was paired with for the rollout who was cool as a cucumber and helped me spot the issue... I was bricking it!
