John the Ripper is a perfectly safe program to install and run, as most popular UNIX tools. If you are running a multi-user system, you should make sure you are shadowing your password file such that the hashes are not visible; however even if you are not, not installing John will not prevent a malicious user from running John on their own ...
crypt is a POSIX C library function. It is typically used to compute the hash of user account passwords. The function outputs a text string which also encodes the salt (usually the first two characters are the salt itself and the rest is the hashed result), and identifies the hash algorithm used (defaulting to the "traditional" one explained below).
