# SSL/TLS OPTIONS
# These directives allow you to specify how to use SSL/TLS.

# SSL VERSION
# This can be any of: SSLv2 (only use SSLv2), SSLv2+ (use any version),
#        SSLv3 (only use SSLv3), SSLv3+ (use SSLv3 or above), TLSv1 (only use
#        TLSv1), TLSv1+ (use TLSv1 or above), TLSv1.1 (only use TLSv1.1),
#        TLSv1.1+ (use TLSv1.1 or above), TLSv1.2 (only use TLSv1.2),
#        TLSv1.2+ (use TLSv1.2 or above)
# If an "or above" version is used, the best will be negotiated. So if both
# ends are able to do TLSv1.2 and use specify SSLv2, you will get TLSv1.2.

#ssl_version=SSLv2+

# SSL USE ADH
# This is for backward compatibility and is DEPRECATED. Set to 1 to enable
# ADH or 2 to require ADH. 1 is currently the default but will be changed
# in a later version.

#ssl_use_adh=1

# SSL CIPHER LIST
# This lists which ciphers can be used. For backward compatibility, this
# defaults to 'ssl_cipher_list=ALL:!MD5:\@STRENGTH' in this version but
# will be changed to something like the example below in a later version of NRPE.

#ssl_cipher_list=ALL:!MD5:\@STRENGTH
#ssl_cipher_list=ALL:!aNULL:!eNULL:!SSLv2:!LOW:!EXP:!RC4:!MD5:\@STRENGTH

# SSL Certificate and Private Key Files

#ssl_cacert_file=/etc/ssl/servercerts/ca-cert.pem
#ssl_cert_file=/etc/ssl/servercerts/nagios-cert.pem
#ssl_privatekey_file=/etc/ssl/servercerts/nagios-key.pem

# SSL USE CLIENT CERTS
# This options determines client certificate usage.
# Values: 0 = Don't ask for or require client certificates (default)
#         1 = Ask for client certificates
#         2 = Require client certificates

#ssl_client_certs=0

# SSL LOGGING
# This option determines which SSL messages are send to syslog. OR values
# together to specify multiple options.

# Values: 0x00 (0)  = No additional logging (default)
#         0x01 (1)  = Log startup SSL/TLS parameters
#         0x02 (2)  = Log remote IP address
#         0x04 (4)  = Log SSL/TLS version of connections
#         0x08 (8)  = Log which cipher is being used for the connection
#         0x10 (26) = Log if client has a certificate
#         0x20 (32) = Log details of client's certificate if it has one
#         -1 or 0xff or 0x2f = All of the above
