OpenSSL applications can also use the +\&\s-1CONF\s0 library for their own purposes. +.PP +A configuration file is divided into a number of sections. Each section +starts with a line \fB[ section_name ]\fR and ends when a new section is +started or end of file is reached. A section name can consist of +alphanumeric characters and underscores. +.PP +The first section of a configuration file is special and is referred +to as the \fBdefault\fR section this is usually unnamed and is from the +start of file until the first named section. When a name is being looked up +it is first looked up in a named section (if any) and then the +default section. +.PP +The environment is mapped onto a section called \fB\s-1ENV\s0\fR. +.PP +Comments can be included by preceding them with the \fB#\fR character +.PP +Each section in a configuration file consists of a number of name and +value pairs of the form \fBname=value\fR +.PP +The \fBname\fR string can contain any alphanumeric characters as well as +a few punctuation symbols such as \fB.\fR \fB,\fR \fB;\fR and \fB_\fR. +.PP +The \fBvalue\fR string consists of the string following the \fB=\fR character +until end of line with any leading and trailing white space removed. +.PP +The value string undergoes variable expansion. This can be done by +including the form \fB\f(CB$var\fB\fR or \fB${var}\fR: this will substitute the value +of the named variable in the current section. It is also possible to +substitute a value from another section using the syntax \fB\f(CB$section::name\fB\fR +or \fB${section::name}\fR. By using the form \fB\f(CB$ENV::name\fB\fR environment +variables can be substituted. It is also possible to assign values to +environment variables by using the name \fBENV::name\fR, this will work +if the program looks up environment variables using the \fB\s-1CONF\s0\fR library +instead of calling \fB\f(BIgetenv()\fB\fR directly. +.PP +It is possible to escape certain characters by using any kind of quote +or the \fB\e\fR character. By making the last character of a line a \fB\e\fR +a \fBvalue\fR string can be spread across multiple lines. In addition +the sequences \fB\en\fR, \fB\er\fR, \fB\eb\fR and \fB\et\fR are recognized. +.SH "OPENSSL LIBRARY CONFIGURATION" +.IX Header "OPENSSL LIBRARY CONFIGURATION" +In OpenSSL 0.9.7 and later applications can automatically configure certain +aspects of OpenSSL using the master OpenSSL configuration file, or optionally +an alternative configuration file. The \fBopenssl\fR utility includes this +functionality: any sub command uses the master OpenSSL configuration file +unless an option is used in the sub command to use an alternative configuration +file. +.PP +To enable library configuration the default section needs to contain an +appropriate line which points to the main configuration section. The default +name is \fBopenssl_conf\fR which is used by the \fBopenssl\fR utility. Other +applications may use an alternative name such as \fBmyapplicaton_conf\fR. +.PP +The configuration section should consist of a set of name value pairs which +contain specific module configuration information. The \fBname\fR represents +the name of the \fIconfiguration module\fR the meaning of the \fBvalue\fR is +module specific: it may, for example, represent a further configuration +section containing configuration module specific information. E.g. +.PP +.Vb 1 +\& openssl_conf = openssl_init +\& +\& [openssl_init] +\& +\& oid_section = new_oids +\& engines = engine_section +\& +\& [new_oids] +\& +\& ... new oids here ... +\& +\& [engine_section] +\& +\& ... engine stuff here ... +.Ve +.PP +Currently there are two configuration modules. One for \s-1ASN1\s0 objects another +for \s-1ENGINE\s0 configuration. +.SS "\s-1ASN1 OBJECT CONFIGURATION MODULE\s0" +.IX Subsection "ASN1 OBJECT CONFIGURATION MODULE" +This module has the name \fBoid_section\fR. The value of this variable points +to a section containing name value pairs of OIDs: the name is the \s-1OID\s0 short +and long name, the value is the numerical form of the \s-1OID.\s0 Although some of +the \fBopenssl\fR utility sub commands already have their own \s-1ASN1 OBJECT\s0 section +functionality not all do. By using the \s-1ASN1 OBJECT\s0 configuration module +\&\fBall\fR the \fBopenssl\fR utility sub commands can see the new objects as well +as any compliant applications. For example: +.PP +.Vb 1 +\& [new_oids] +\& +\& some_new_oid = 1.2.3.4 +\& some_other_oid = 1.2.3.5 +.Ve +.PP +In OpenSSL 0.9.8 it is also possible to set the value to the long name followed +by a comma and the numerical \s-1OID\s0 form. For example: +.PP +.Vb 1 +\& shortName = some object long name, 1.2.3.4 +.Ve +.SS "\s-1ENGINE CONFIGURATION MODULE\s0" +.IX Subsection "ENGINE CONFIGURATION MODULE" +This \s-1ENGINE\s0 configuration module has the name \fBengines\fR. The value of this +variable points to a section containing further \s-1ENGINE\s0 configuration +information. +.PP +The section pointed to by \fBengines\fR is a table of engine names (though see +\&\fBengine_id\fR below) and further sections containing configuration informations +specific to each \s-1ENGINE.\s0 +.PP +Each \s-1ENGINE\s0 specific section is used to set default algorithms, load +dynamic, perform initialization and send ctrls. The actual operation performed +depends on the \fIcommand\fR name which is the name of the name value pair. The +currently supported commands are listed below. +.PP +For example: +.PP +.Vb 1 +\& [engine_section] +\& +\& # Configure ENGINE named "foo" +\& foo = foo_section +\& # Configure ENGINE named "bar" +\& bar = bar_section +\& +\& [foo_section] +\& ... foo ENGINE specific commands ... +\& +\& [bar_section] +\& ... "bar" ENGINE specific commands ... +.Ve +.PP +The command \fBengine_id\fR is used to give the \s-1ENGINE\s0 name. If used this +command must be first. For example: +.PP +.Vb 3 +\& [engine_section] +\& # This would normally handle an ENGINE named "foo" +\& foo = foo_section +\& +\& [foo_section] +\& # Override default name and use "myfoo" instead. +\& engine_id = myfoo +.Ve +.PP +The command \fBdynamic_path\fR loads and adds an \s-1ENGINE\s0 from the given path. It +is equivalent to sending the ctrls \fB\s-1SO_PATH\s0\fR with the path argument followed +by \fB\s-1LIST_ADD\s0\fR with value 2 and \fB\s-1LOAD\s0\fR to the dynamic \s-1ENGINE.\s0 If this is +not the required behaviour then alternative ctrls can be sent directly +to the dynamic \s-1ENGINE\s0 using ctrl commands. +.PP +The command \fBinit\fR determines whether to initialize the \s-1ENGINE.\s0 If the value +is \fB0\fR the \s-1ENGINE\s0 will not be initialized, if \fB1\fR and attempt it made to +initialized the \s-1ENGINE\s0 immediately. If the \fBinit\fR command is not present +then an attempt will be made to initialize the \s-1ENGINE\s0 after all commands in +its section have been processed. +.PP +The command \fBdefault_algorithms\fR sets the default algorithms an \s-1ENGINE\s0 will +supply using the functions \fB\f(BIENGINE_set_default_string()\fB\fR +.PP +If the name matches none of the above command names it is assumed to be a +ctrl command which is sent to the \s-1ENGINE.\s0 The value of the command is the +argument to the ctrl command. If the value is the string \fB\s-1EMPTY\s0\fR then no +value is sent to the command. +.PP +For example: +.PP +.Vb 1 +\& [engine_section] +\& +\& # Configure ENGINE named "foo" +\& foo = foo_section +\& +\& [foo_section] +\& # Load engine from DSO +\& dynamic_path = /some/path/fooengine.so +\& # A foo specific ctrl. +\& some_ctrl = some_value +\& # Another ctrl that doesn\*(Aqt take a value. +\& other_ctrl = EMPTY +\& # Supply all default algorithms +\& default_algorithms = ALL +.Ve +.SH "NOTES" +.IX Header "NOTES" +If a configuration file attempts to expand a variable that doesn't exist +then an error is flagged and the file will not load. This can happen +if an attempt is made to expand an environment variable that doesn't +exist. For example in a previous version of OpenSSL the default OpenSSL +master configuration file used the value of \fB\s-1HOME\s0\fR which may not be +defined on non Unix systems and would cause an error. +.PP +This can be worked around by including a \fBdefault\fR section to provide +a default value: then if the environment lookup fails the default value +will be used instead. For this to work properly the default value must +be defined earlier in the configuration file than the expansion. See +the \fB\s-1EXAMPLES\s0\fR section for an example of how to do this. +.PP +If the same variable exists in the same section then all but the last +value will be silently ignored. In certain circumstances such as with +DNs the same field may occur multiple times. This is usually worked +around by ignoring any characters before an initial \fB.\fR e.g. +.PP +.Vb 2 +\& 1.OU="My first OU" +\& 2.OU="My Second OU" +.Ve +.SH "EXAMPLES" +.IX Header "EXAMPLES" +Here is a sample configuration file using some of the features +mentioned above. +.PP +.Vb 1 +\& # This is the default section. +\& +\& HOME=/temp +\& RANDFILE= ${ENV::HOME}/.rnd +\& configdir=$ENV::HOME/config +\& +\& [ section_one ] +\& +\& # We are now in section one. +\& +\& # Quotes permit leading and trailing whitespace +\& any = " any variable name " +\& +\& other = A string that can \e +\& cover several lines \e +\& by including \e\e characters +\& +\& message = Hello World\en +\& +\& [ section_two ] +\& +\& greeting = $section_one::message +.Ve +.PP +This next example shows how to expand environment variables safely. +.PP +Suppose you want a variable called \fBtmpfile\fR to refer to a +temporary filename. The directory it is placed in can determined by +the the \fB\s-1TEMP\s0\fR or \fB\s-1TMP\s0\fR environment variables but they may not be +set to any value at all. If you just include the environment variable +names and the variable doesn't exist then this will cause an error when +an attempt is made to load the configuration file. By making use of the +default section both values can be looked up with \fB\s-1TEMP\s0\fR taking +priority and \fB/tmp\fR used if neither is defined: +.PP +.Vb 5 +\& TMP=/tmp +\& # The above value is used if TMP isn\*(Aqt in the environment +\& TEMP=$ENV::TMP +\& # The above value is used if TEMP isn\*(Aqt in the environment +\& tmpfile=${ENV::TEMP}/tmp.filename +.Ve +.SH "BUGS" +.IX Header "BUGS" +Currently there is no way to include characters using the octal \fB\ennn\fR +form. Strings are all null terminated so nulls cannot form part of +the value. +.PP +The escaping isn't quite right: if you want to use sequences like \fB\en\fR +you can't use any quote escaping on the same line. +.PP +Files are loaded in a single pass. This means that an variable expansion +will only work if the variables referenced are defined earlier in the +file. +.SH "SEE ALSO" +.IX Header "SEE ALSO" +\&\fIx509\fR\|(1), \fIreq\fR\|(1), \fIca\fR\|(1) diff --git a/usr/man/man5/x509v3_config.5 b/usr/man/man5/x509v3_config.5 new file mode 100755 index 000000000..faeffb89d --- /dev/null +++ b/usr/man/man5/x509v3_config.5 @@ -0,0 +1,610 @@ +.\" Automatically generated by Pod::Man 2.28 (Pod::Simple 3.28) +.\" +.\" Standard preamble: +.\" ======================================================================== +.de Sp \" Vertical space (when we can't use .PP) +.if t .sp .5v +.if n .sp +.. +.de Vb \" Begin verbatim text +.ft CW +.nf +.ne \\$1 +.. +.de Ve \" End verbatim text +.ft R +.fi +.. +.\" Set up some character translations and predefined strings. \*(-- will +.\" give an unbreakable dash, \*(PI will give pi, \*(L" will give a left +.\" double quote, and \*(R" will give a right double quote. \*(C+ will +.\" give a nicer C++.

The short form +is a list of names and values: +.PP +.Vb 1 +\& basicConstraints=critical,CA:true,pathlen:1 +.Ve +.PP +The long form allows the values to be placed in a separate section: +.PP +.Vb 1 +\& basicConstraints=critical,@bs_section +\& +\& [bs_section] +\& +\& CA=true +\& pathlen=1 +.Ve +.PP +Both forms are equivalent. +.PP +The syntax of raw extensions is governed by the extension code: it can +for example contain data in multiple sections. The correct syntax to +use is defined by the extension code itself: check out the certificate +policies extension for an example. +.PP +If an extension type is unsupported then the \fIarbitrary\fR extension syntax +must be used, see the \s-1ARBITRART EXTENSIONS\s0 section for more details. +.SH "STANDARD EXTENSIONS" +.IX Header "STANDARD EXTENSIONS" +The following sections describe each supported extension in detail. +.SS "Basic Constraints." +.IX Subsection "Basic Constraints." +This is a multi valued extension which indicates whether a certificate is +a \s-1CA\s0 certificate.
