A few years ago I made a password protected disk image - I've long since forgotten the password. Can I reset it?
 
No. Disk Utility warns you when making encrypted disk images that the data on them cannot be recovered if the password is lost. Because...that is kind of the point of an encrypted disk image. No password = data is not readable.
 
Surely there must be some way for some entity to figure out that password and access the file?

Are you telling me that FBI encryption speciallists couldn't access the file's contents?
 
Shouldn't that be SOOL?

Anyway, let's not get bogged down in the semantics of sad net speak. Thanks anyway for the help. I guess I'll never know what's in that .dmg!

Encrypted disk images are encrypted with AES-128 or -256. This is one of the most secure algorithms in existence, and has withstood years of numerous high-powered cracking attempts. The NSA uses it to encrypt their data. If you lost the password, it's gone.

Beat me to it...... You are basically out of luck. Good luck with trying to get anything off of it. Do a little research if you don't believe what what is being said here.
 
There's always a brute force attack, which means trying every possible combination of characters until you get in, but that could take years.

If you're talking AES, it would take many more years than the universe has been around for.
