radcrypt

RADCRYPT(8)						      System Manager's Manual						       RADCRYPT(8)

NAME

       radcrypt - generate password hash for use with radius, or validates a password hash

SYNOPSIS

       radcrypt [-d|--des] [-m|--md5] [-c|--check] plaintext_password [hashed_password]

DESCRIPTION

       radcrypt  generates  a  hashed digest of a plaintext password, or can validate if a password hash matches a plaintext password. DES and MD5
       hashes are currently supported. When generating a password hash a random salt is generated and applied.

       A hashed password can be validated by specifying -c or --check and passing hashed_password after plaintext_password on  the  command  line.
       In this case hashed_password will be checked to see if it matches plaintext_password. If so "Password OK" will be printed and the exit sta-
       tus will be 1, otherwise "Password BAD" will be printed and exit status will be 0 (Note this is the opposite of a normal  successful  shell
       status).

OPTIONS

       -d --des
	      Use a DES (Data Encryption Standard) hash (default).  Ignored if performing a password check.

       -m --md5
	      Use a MD5 (Message Digest 5) hash.  Ignored if performing a password check.

       -c --check
	      Perform a validation check on a password hash to verify if it matches the plantext password.

EXAMPLES

       $ radcrypt foobar
       HaX0xn7Qy650Q
       $ radcrypt -c foobar HaX0xn7Qy650Q
       Password OK
