It is a symmetric block cipher, which means that the same key is used for disk encryption and decryption. The objective of AES is to provide a specification for electronic data encryption. It was established by the United States National Institute of Standards and Technology (NIST) in 2001. The Advanced Encryption Standard (AES) is one of the widely used global standards for encryption. The primary purpose of encrypting external hard drives is to protect their data from unauthorized persons.
It provides security to your external hard drive against hackers and other online threats. This can be done by using software or some other way.Īfter disk encryption, the data on the external hard drive cannot be accessed by anyone who doesn’t own the relevant key or password. How does Encrypting an External Hard Drive or USB WorkĮncrypting an external hard drive means making it secure by encrypting the data stored using sophisticated mathematical functions.
