Password Encryption (SunOS 5.8)
Hi all,
I have a server in the office that we connect to via telnet. Can anyone explain please how i can encrypt the password so it cannot be picked up in plain text by sniffing software like WireShark, etc.?
I'm not very experienced in Unix, so any ideas or even links would be great.
Appreciate the assistance.

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
