Tcl API Reference -- ns_crypt

### ns_crypt

#### Overview

Encrypt password

#### Syntax

ns_crypt key salt

#### Description

ns_crypt encrypts the key using the salt and returns the result. It uses the same algorithm as the Unix crypt command. Normally key is the user's password and salt is a two-character code used to encrypt the key.

#### Example

Suppose you have a user nevsky with a password alexander. Nevsky's /etc/passwd entry might look like:

        nevsky:/gteiXVtAXVqQ:28:1:Musician:/:/bin/sh

The first two characters of the encrypted password are the SALT. Since

        ns_crypt /g alexander

returns`/gte...Q`, then alexander is the correct password.
