srptool(1) General Commands Manual srptool(1)NAMEsrptool - Simple SRP password toolSYNOPSISsrptool [options]DESCRIPTIONVery 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--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. -c, --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.EXAMPLESTo 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 testAUTHORNikos Mavrogiannopoulos <nmav@gnutls.org> and others; see /usr/share/doc/gnutls-bin/AUTHORS for a complete list.
