NAME
srptool - Simple SRP password toolSYNOPSIS
srptool [options]DESCRIPTION
Very simple program that emulates the programs in the Stanford SRP (Secure Remote Password) libraries using GNU TLS. 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
- --bits BITS
- specify the number of bits for prime numbers (used only when the --create-conf option is used).
- --create-conf FILE
- Generate a tpasswd.conf file.
- -h, --help
- Prints a short reminder of the command line options.
- -i, --index INDEX
- Specify the index of the parameters in tpasswd.conf to use.
- -p, --passwd FILE
- Specify a password file.
- --passwd-conf FILE
- Specify a password configuration file.
- -s, --salt SALT
- Specify salt size for crypt algorithm.
- -u, --username username
- Specify username.
- --verify
- Just verify password.
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
