    A few years ago I created a 100MB disk image using Disk Utility in which to store my sensitive files. I've hit the limit, and so I created a new one that is 500MB. I was sure to select the encryption option and to set a password. However, this new one is not requiring my password to open it! When I double click on the disk image, the image mounts without a password prompt. I've tried this multiple times on different settings, logged out and in, etc., and I still can't get it to work. What's wrong?


    Hm. Figured it out. The OS had saved my password in Keychain.

    Good to know. Another option is probably a disk image and a certificate which is stored in the current “open” keychain. In that case OS X should mount the encrypted disk image without a password. I always thought that the OS X keychain is not a good place to store passwords or certificates.

    I use also AES-256 encrypted sparse disk images for certain files or information archives (with a very long, complex pass phrase). AFAIK they are backwards compatible to Mac OS X 10.5.x.
