Are encrypted DMG safe?
dmg is pretty darn secure. In 2003, the US Government stated that “…the AES algorithm (i.e., 128, 192 and 256) are sufficient to protect classified information up to the SECRET level.” The original files, before they’re encrypted, lie out in plain sight unless you secure delete them in the Finder.

Are Apple Macs encrypted?
