Excuse me, could you please clarify something for me? I've been reading up on BitLocker and I'm wondering, does BitLocker have an expiration date? I mean, is there a point in time where the encryption provided by BitLocker will no longer be valid or functional? I want to ensure that my data remains secure for the long term and I'm wondering if I need to take any additional steps to maintain the protection provided by BitLocker. Thanks in advance for your help!
