Description

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In Unix computing, crypt is the name of both a utility program and a C programming function. Though both are used for encrypting data, they are otherwise essentially unrelated. To distinguish between the two, writers often refer to the utility program as crypt, because it is documented in section 1 of the Unix manual pages, and refer to the C library function as crypt, because its documentation is in manual section 3. crypt is a simple command to encrypt or decrypt data. Usually this is used as a filter and it has traditionally been implemented using an algorithm based on the Enigma machine. It is considered to be far too cryptographically weak to provide any security against brute force attacks by modern, commodity personal computers.show more
