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.

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