When booting my laptop today I found that
ssh (openssh) simply refuses to accept my passphrase when reading my private key. My only idea of how that could've happened is if the HDD has somehow corrupted the key, but I figure that if that is the case I'd probably notice system instability in other ways too.
This isn't that much of a chore for me, since I can access all the places where that key is used using some other means, and I've been meaning to generate a new (bigger) key anyway. I'd still like to figure out what happened though, so any ideas on what could've caused this are welcome. I'm absolutely sure that I'm not typoing the passphrase.
