NAME

       gnutls-cli - GnuTLS test client

SYNOPSIS

       gnutls-cli [options] hostname

DESCRIPTION

       Simple client program to set up a TLS connection to some other computer.  It sets up a TLS
       connection and forwards data from the standard input to the secured socket and vice versa.

OPTIONS

   Program control options
       -d, --debug LEVEL
              Specify the debug level. Default is 1.

       -h, --help
              Prints a short reminder of the command line options.

       -l, --list
              Print a list of the supported algorithms and modes.

       -r, --resume
              Connect, establish a session.  Connect again and resume this session.

       -s, --starttls
              Connect, establish a plain session and start TLS when EOF or a SIGALRM is received.

       -v, --version
              Prints the program's version number.

       -V, --verbose
              More verbose output.

   TLS/SSL control options
       --priority PRIORITY STRING
              TLS  algorithms  and  protocols  to  enable.   You  can  use  predefined  sets   of
              ciphersuites such as:

              PERFORMANCE  all  the "secure" ciphersuites are enabled, limited to 128 bit ciphers
              and sorted by terms of speed performance.

              NORMAL option enables all "secure" ciphersuites. The 256-bit ciphers  are  included
              as a fallback only. The ciphers are sorted by security margin.

              SECURE128  flag  enables  all  "secure"  ciphersuites  with ciphers up to 128 bits,
              sorted by security margin.

              SECURE256 flag enables all "secure" ciphersuites including  the  256  bit  ciphers,
              sorted by security margin.

              EXPORT all the ciphersuites are enabled, including the low-security 40 bit ciphers.

              NONE nothing is enabled. This disables even protocols and compression methods.

              Check  the  GnuTLS  manual  on  section  "Priority strings" for more information on
              allowed keywords.

              Examples:

              "NORMAL"

              "NONE:+VERS-TLS-ALL:+MAC-ALL:+RSA:+AES-128-CBC:+SIGN-ALL:+COMP-NULL"

              "NORMAL:-ARCFOUR-128" means normal ciphers except for ARCFOUR-128.

              "SECURE:-VERS-SSL3.0:+COMP-DEFLATE" means that only  secure  ciphers  are  enabled,
              SSL3.0 is disabled, and libz compression enabled.

               "NONE:+VERS-TLS-ALL:+AES-128-CBC:+RSA:+SHA1:+COMP-NULL:+SIGN-RSA-SHA1"

              "NORMAL:%COMPAT" is the most compatible mode

       --crlf Send CR LF instead of LF.

       -f, --fingerprint
              Send the openpgp fingerprint, instead of the key.

       -p, --port integer
              The port to connect to.

       --kx kx1 kx2...
              Key exchange methods to  enable  (use  gnutls-cli  --list  to  show  the  supported
              methods).

       --ctypes certType1 certType2...
              Certificate types to enable (use gnutls-cli --list to show the supported types).

       --recordsize integer
              The maximum record size to advertize.

       --disable-extensions
              Disable all the TLS extensions.
