ENCRYPT(1) FreeBSD General Commands Manual ENCRYPT(1)
NAME
encrypt - encrypt passwords from the command line or standard input
SYNOPSIS
encrypt [-b rounds] [-c class] [-p | string]
DESCRIPTION
encrypt prints the encrypted form of string to the standard output. This
is mostly useful for encrypting passwords from within scripts.
The options are as follows:
-b rounds
Encrypt the string using Blowfish hashing with the specified
number of rounds. May also specify 'a' to request a variable
number of rounds scaled to the machine's CPU capabilities.
-c class
Use the cipher type specified in the given user login class. See
login.conf(5) for more information.
-p Prompt for a single string with echo turned off.
If no string is specified, encrypt reads one string per line from
standard input, encrypting each one. In the case where no specific
algorithm or specific user login class was given as a command line
option, the algorithm specified in the default class in /etc/login.conf
will be used.
For Blowfish, a new random salt is automatically generated for each
password.
Specifying the string on the command line should be discouraged; using
the standard input is more secure.
