Specify the debug level. Default is 1.
-h, --help
prints this help
-l, --list
Print a list of the supported algorithms and modes.
-q, --quiet

Server options

-p, --port integer
The port to listen on.
Does not use the resume database.

TLS/SSL control options

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.
"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.

"NORMAL:%COMPAT" is the most compatible mode

-g, --generate
Generate Diffie-Hellman Parameters.
--kx kx1 kx2...
Key exchange methods to enable (use gnutls-cli --list to show the supported key exchange methods).
-p, --port integer
The port to connect to.

--pgptrustdb FILE
PGP trustdb file to use.
--srppasswd FILE
SRP password file to use.
--srppasswdconf FILE
