TrueCrypt

TrueCrypt is a software program that allows users to create secure, encrypted storage containers—virtual "vaults"—on their computer or external drives. These vaults act like normal files, but their contents are scrambled so that only someone with the correct password can access the data. It uses strong cryptographic algorithms to protect sensitive information from unauthorized access. Even if someone steals the storage device, they cannot read the protected data without the password. TrueCrypt is commonly used for safeguarding personal and confidential information, providing a high level of security and privacy.
