VeraCrypt is a full disk and partition encryption system that gives you flexibility and enables you to choose what to encrypt. It uses 256-bit AES encryption by default, but you can choose other methods, including Camellia, Kuznyechik, Serpent, and Twofish, all of which use a 256-bit key. You can even use a combination of two or three.
