NAME¶
srptool - GnuTLS SRP tool
SYNOPSIS¶
srptool [
-flags] [
-flag [
value]] [
--option-name[[=| ]
value]]
All arguments must be options.
DESCRIPTION¶
Simple program that emulates the programs in the Stanford SRP (Secure Remote
Password) libraries using GnuTLS. It is intended for use in places where you
don't expect SRP authentication to be the used for system users.
In brief, to use SRP you need to create two files. These are the password file
that holds the users and the verifiers associated with them and the
configuration file to hold the group parameters (called tpasswd.conf).
OPTIONS¶
- -d number, --debug=number
-
Enable debugging. This option takes an integer number as its argument. The
value of number is constrained to being:
in the range 0 through 9999
Specifies the debug level.
- -i number, --index=number
-
specify the index of the group parameters in tpasswd.conf to use. This
option takes an integer number as its argument. The default number
for this option is:
1
- -u string, --username=string
-
specify a username.
- -p string, --passwd=string
-
specify a password file.
- -s number, --salt=number
-
specify salt size. This option takes an integer number as its argument.
- --verify
-
just verify the password..
Verifies the password provided against the password file.
- -v string, --passwd-conf=string
-
specify a password conf file..
Specify a filename or a PKCS #11 URL to read the CAs from.
- --create-conf=string
-
Generate a password configuration file..
This generates a password configuration file (tpasswd.conf) containing the
required for TLS parameters.
- -h, --help
-
Display usage information and exit.
- -!, --more-help
-
Pass the extended usage information through a pager.
- -v [{v|c|n --version [{v|c|n}]}]
-
Output version of program and exit. The default mode is `v', a simple
version. The `c' mode will print copyright information and `n' will print
the full copyright notice.
EXAMPLES¶
To create
tpasswd.conf which holds the g and n values for SRP protocol
(generator and a large prime), run:
$ srptool --create-conf /etc/tpasswd.conf
This command will create
/etc/tpasswd and will add user 'test' (you will
also be prompted for a password). Verifiers are stored by default in the way
libsrp expects.
$ srptool --passwd /etc/tpasswd --passwd-conf /etc/tpasswd.conf -u test
This command will check against a password. If the password matches the one in
/etc/tpasswd you will get an ok.
$ srptool --passwd /etc/tpasswd --passwd-conf /etc/tpasswd.conf --verify -u test
EXIT STATUS¶
One of the following exit values will be returned:
- 0 (EXIT_SUCCESS)
-
Successful program execution.
- 1 (EXIT_FAILURE)
-
The operation failed or the command syntax was not valid.
- 70 (EX_SOFTWARE)
-
libopts had an internal operational error. Please report it to
autogen-users@lists.sourceforge.net. Thank you.
