I was hoping there would be some way of doing this directly from bash, but going for the perl method is not a problem.

As rweaver pointed out, and I'm not too big to admit, I was wrong.

Try:

Code:

#!/bin/bash
Password="Testing"
###
### Create encrypted password
###
l_encrypted_pass=$(mkpasswd --hash=md5 $Password)

echo "$l_encrypted_pass"

I may have mentioned this before, but it looks like my version of mkpasswd doesn't have flags such as "hash". I've got flags to define the minimum number of special characters and so forth, but not hash type. Where did you guys get your mkpasswd package?

For me, mkpasswd was already installed.

This is an old "feisty fawn" Ubuntu installation.

mkpasswd -V gives:

But, if you can't get mkpasswd to do what you need, there is still the perl script

I looks like my mkpasswd command is part of the "expect" package, so I'm guessing that maybe your mkpasswd is different than mine. My mkpasswd doesn't even have a "-V" option.

I think I'll have to settle with the perl script, then.

Strange, do a man on mkpasswd, you may have --hash but not md5 (aes, blowfish maybe?)

You can try this:

mkpasswd --hash=help

and it should display any available.

Yeah, it's strange. I don't have any hash option at all - I've searched the man page, and I've entered your command above. Is your mkpasswd part of another package, or did is come as a separate package?

I've got three systems in front of me that I just checked, it's in my base install on all of them, strangely enough it seems to be coming from the "whois" package O_o. Although at one time I'm almost positive it came from the "bsdutils" package.

I guess I'll have to accept that we simply have to different implementations of mkpasswd, and yours is definately superior.

At least I know where to find yours if I need it later on. Thanks for the help anyway.

FWIW (on SimplyMEPIS 7.0, 32-bit, "official"):

Code:

$ mkpasswd -V
GNU mkpasswd 4.7.20

rweaver, I'm curious -- what version do you have?

kenneho, I assume that "no -V" means no "--version" or other equivalent.

I do seem to have hashing, but not md5:

Code:

$ mkpasswd -h
Usage: mkpasswd [OPTIONS]... [PASSWORD [SALT]]
Crypts the PASSWORD using crypt(3).

      -H, --hash=TYPE       select hash TYPE
      -S, --salt=SALT       use the specified SALT
      -P, --password-fd=NUM read the password from file descriptor NUM
                            instead of /dev/tty
      -s, --stdin           like --password-fd=0
      -h, --help            display this help and exit
      -V, --version         output version information and exit

If PASSWORD is missing then it is asked interactively.
If no SALT is specified, a random one is generated.
If TYPE is 'help', available algorithms are printed.

That's correct. No version, hash or many other options. :/
