crypt

NAME

crypt() - encrypt a string

SYNOPSIS

string crypt( string str, string seed );

DESCRIPTION

Encrypt the string `str` using string `seed`. If `seed` is zero, then
a random seed will be used.

The encrypted result can be used as the `seed` of a second encrypt,
which will return the original encrypted result if both `str` inputs
were identical.

NOTE

The encryption methods of FluffOS and MudOS are different. For MudOS
compatibity you should use oldcrypt().

EXAMPLE

Example of verifying a password using crypt():

// turn user input into crypted password
string cryptPasswd = crypt(input, 0);

// store crypted password in user save somewhere

// compare login input to stored crypted password
if (crypt(input, cryptPasswd) == cryptPasswd) {
    // valid password
} else {
    // invalid password attempt
}
