No unencrypted
key is ever stored to
disk unless you choose not to set a spending password /

disk encryption programs including Microsoft BitLocker, Apple FileVault, PGPdisk and TrueCrypt that typically create an encrypted volume on a computer's hard drive or encrypt the entire hard drive using a

disk encryption and Windows will use a TPM to store the

encryption on a computer with the TPM, part of the
key is stored in the TPM itself, rather than just on the
disk.
