How is the USB disk generally encrypted?

Now U disk is almost one person, and many people use it to store their important data. For this reason, the USB flash drive brings us convenience as well as data security issues. Therefore, we generally need to encrypt the U disk when storing important data. Now let's understand what types of encryption are available. Encryption can be divided into two types, hardware encryption and software encryption. 1: Hardware, software encryption, different hardware encryption for keyboard encryption, swipe encryption, fingerprint encryption. Software encryption mainly includes password encryption, certificate encryption, and CD encryption. 2: Commonly used software encryption types In summary, both have their own advantages. Hardware encryption is more reliable than data encryption in terms of data security, and it is plug-and-play, eliminating the need to install encrypted password software, which is more convenient to use. Software encryption is lower in technology and cost than hardware encryption, easy to implement, and cost-effective. Therefore, products that use software encryption on the market are cheaper than hardware encryption products. 3: Hardware Encryption vs. Software Encryption From a security perspective, software encryption is easier to crack than hardware encryption. Extreme methods such as brute force software, formatting products, and dismantling flash chips for storing data can be easily cracked. Software encryption. Relatively speaking, hardware encryption is hardened in the hardware control chip because the encryption technology is hardened. The entire encryption process leaves almost no trace on the computer. The password transmission process is also transmitted in cipher text, so it is difficult to be intercepted by the Trojan. It is also garbled, so the possibility of cracking is very low.
