'''NAME'''

: ns_crypt - Encrypt a string for use as a password

'''SYNOPSIS'''

: '''ns_crypt''' ''key salt''

'''DESCRIPTION'''

: This command encrypts the ''key'' using the ''salt'' and returns the encrypted string. It uses the same algorithm as the Unix crypt command.

: Normally, ''key'' is a password, of which the first 8 bytes are significant, and ''salt'' is one or two bytes used to encrypt the ''key''. The string returned should always be 13 characters long and is usable as the password field in [[nscp]] and [[nsperm]] authentication.

: The algorithm used is a one-way cipher, which means that the original plain-text ''key'' cannot be derived knowing the encrypted string alone. However, since only up to the first 8 bytes of ''key'' are significant, this means only a 64-bit key, which is reasonably attacked with modern computers with ordinary brute-force attacks today.

'''EXAMPLES'''

% ns_crypt password qy
