6 /* SUMMARY
7 /*	convert Cyrus SASL security properties to bit mask
8 /* SYNOPSIS

10 /*
11 /*	int	xsasl_cyrus_security_parse_opts(properties)
12 /*	const char *properties;
13 /* DESCRIPTION
14 /*	xsasl_cyrus_security_parse_opts() converts a list of security
15 /*	properties to a bit mask. The result is zero in case of error.
16 /*
17 /*	Arguments:
18 /* .IP properties
19 /*	A comma or space separated list of zero or more of the
20 /*	following:
21 /* .RS
22 /* .IP noplaintext
23 /*	Disallow authentication methods that use plaintext passwords.
24 /* .IP noactive
25 /*	Disallow authentication methods that are vulnerable to
26 /*	non-dictionary active attacks.
27 /* .IP nodictionary
28 /*	Disallow authentication methods that are vulnerable to
29 /*	passive dictionary attack.
30 /* .IP forward_secrecy
31 /*	Require forward secrecy between sessions.
32 /* .IP noanonymous
33 /*	Disallow anonymous logins.
