Ccrypt
What Does Activation Key Mean?
An activation key is a code to register or activate a software application. It usually consists of letters and numbers with a dotted fundamental movement between sections. Newer models of software products eliminate the activation key as an authorization mechanism. With the development of cloud computing services, many types of software have been purchased online and used online on a subscription basis. It eliminates the need to use activation keys to authenticate users. An activation key is a by-product of the system where the user purchases the code and execution software for the application and downloads all of the code to their computer or device. New methods are rapidly replacing the traditional form of licensing.
Ccrypt is a utility for encrypting and decrypting files and streams. It was designed as a replacement for the standard UNIX crypt utility, which is notorious for using a very weak encryption algorithm. Encryption and decryption depends on a keyword (or key phrase) supplied by the user. By default, the user is prompted to enter a keyword from the terminal. Keywords can consist of any number of characters, and all characters are significant (although Ccrypt internally hashes the key to 256 bits). Longer keywords provide better security than short ones, since they are less likely to be discovered by exhaustive search.
