gnutls−cli — GnuTLS test client
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.
−d,
−−debug LEVELSpecify the debug level. Default is 1.
−h,
−−helpPrints a short reminder of the command line options.
−l,
−−listPrint a list of the supported algorithms and modes.
−r,
−−resumeConnect, establish a session. Connect again and resume this session.
−s,
−−starttlsConnect, establish a plain session and start TLS when EOF or a SIGALRM is received.
−v,
−−versionPrints the program's version number.
−V,
−−verboseMore verbose output.
−−priority PRIORITY
STRINGTLS algorithms and protocols to enable. You can use predefined sets of ciphersuites such as:
PERFORMANCEall the "secure" ciphersuites are enabled, limited to 128 bit ciphers and sorted by terms of speed performance.
NORMALoption enables all "secure" ciphersuites. The 256-bit ciphers are included as a fallback only. The ciphers are sorted by security margin.
SECURE128flag enables all "secure" ciphersuites with ciphers up to 128 bits, sorted by security margin.
SECURE256flag enables all "secure" ciphersuites including the 256 bit ciphers, sorted by security margin.
EXPORTall the ciphersuites are enabled, including the low-security 40 bit ciphers.
NONEnothing 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
