Long mount time ?

[Christian Nielsen]

Why does it take VeraCrypt so long time with "Auto-mount device", in TrueCrypt it takes 1 sec. where VeraCrypt 20 sec. if I'm lucky.

[Enigma2Illusion]

VeraCrypt's default iteration count for the hash is much higher to improve security due to advances in hardware technology than TrueCrypt.

VeraCrypt includes custom PIM, Personal Iterations Multiplier to help future proof the software for the user to be able to increase the hash iterations.

So is setting a password and setting PIM = 1 the fastest way to decrypt the
partition?

MOD EDIT: Removed over quoting.

[Enigma2Illusion]

You have to use a password of 20 or more characters to set the PIM to a lower default value.

You can read the details in the Personal Iterations Multiplier documentation.

EDIT:

The password, PIM and keyfiles is only for decrypting the header key using the hash algorithm to extract the encryption key used for reading/writing to the mounted VeraCrypt volume.

The encryption key aka the master key is not using the hash algorithm.

The master keys were generated during the volume creation and cannot be changed later.

OK, also I would be nice if VeraCrypt could be associated with .hc files but can't be done in windows ?. Worked fine in TrueCrypt .tc files.

[Enigma2Illusion]

I have never had any problem with the .hc extension being associated with the VeraCrypt application.

Try reinstalling VeraCrypt and reboot after installation.

EDIT:
During the installation, be sure on the Setup Options screen that the "Associate the .hc file extension with VeraCrypt" box option is checked.

Be sure to install using a Windows account with Administrator privileges.
