Secure Your Dropbox Data with BoxCryptor

by Joel Fernandes 1

Dropbox, a cloud file storage service provider, is the most prominent of all. Dropbox provides a quick and easy way to store and sync your files, photos, docs, and videos in the cloud and share them easily among your friends and family members. However, when your files are uploaded, Dropbox encrypts the files at the sever end by which your files could be accessed by Dropbox and authorities that it grants access.

Recently, due to a security flaw, it was reported that there was a four-hour security glitch at Dropbox where any random user could log into any of the accounts at Dropbox with any password. Although your files were encrypted with Dropbox’s powerful encryption tool, yet it could be accessed by anyone from anywhere. This led to a high security alert.

The best way to secure Dropbox data is to encrypt them before you upload. That way, neither Dropbox authorities can decrypt it nor any hacker and thus your files remain secured, no matter what.
