54 The three macros B<OPENSSL_VERSION_MAJOR>, B<OPENSSL_VERSION_MINOR> and
55 B<OPENSSL_VERSION_PATCH> represent the three parts of a version
56 identifier, B<I<MAJOR>.I<MINOR>.I<PATCH>>.
58 The macro B<OPENSSL_VERSION_PRE_RELEASE> is an added bit of text that,
59 when defined, indicates that this is a pre-release version, such as
60 C<"-dev"> for an ongoing development snapshot or C<"-alpha3"> for an
62 The value must be a string.
64 The macro B<OPENSSL_VERSION_BUILD_METADATA> is extra information, reserved
65 for other parties, such as C<"+fips">, or C<"+vendor.1">.
66 The OpenSSL project will not touch this macro.
67 The value must be a string.
69 B<OPENSSL_VERSION_STR> is a convenience macro to get the short version
70 identifier string, C<"I<MAJOR>.I<MINOR>.I<PATCH>">.
72 B<OPENSSL_FULL_VERSION_STR> is a convenience macro to get the longer
73 version identifier string, which combines B<OPENSSL_VERSION_STR>,
74 B<OPENSSL_VERSION_PRE_RELEASE> and B<OPENSSL_VERSION_BUILD_METADATA>.
76 B<OPENSSL_VERSION_TEXT> is a convenience macro to get a full descriptive
77 version text, which includes B<OPENSSL_FULL_VERSION_STR> and the release
82 OPENSSL_version_major(), OPENSSL_version_minor(), OPENSSL_version_patch(),
83 OPENSSL_version_pre_release(), and OPENSSL_version_build_metadata() return
84 the values of the macros above for the build of the library, respectively.
86 OpenSSL_version() returns different strings depending on I<t>:
92 The value of B<OPENSSL_VERSION_TEXT>
94 =item OPENSSL_VERSION_STRING
96 The value of B<OPENSSL_VERSION_STR>
98 =item OPENSSL_FULL_VERSION_STRING
100 The value of B<OPENSSL_FULL_VERSION_STR>
104 The compiler flags set for the compilation process in the form
105 C<compiler: ...> if available, or C<compiler: information not available>
108 =item OPENSSL_BUILT_ON
110 The date of the build process in the form C<built on: ...> if available
111 or C<built on: date not available> otherwise.
112 The date would not be available in a reproducible build, for example.
114 =item OPENSSL_PLATFORM
116 The "Configure" target of the library build in the form C<platform: ...>
117 if available, or C<platform: information not available> otherwise.
121 The B<OPENSSLDIR> setting of the library build in the form C<OPENSSLDIR: "...">
122 if available, or C<OPENSSLDIR: N/A> otherwise.
124 =item OPENSSL_ENGINES_DIR
126 The B<ENGINESDIR> setting of the library build in the form C<ENGINESDIR: "...">
127 if available, or C<ENGINESDIR: N/A> otherwise.
129 =item OPENSSL_MODULES_DIR
131 The B<MODULESDIR> setting of the library build in the form C<MODULESDIR: "...">
132 if available, or C<MODULESDIR: N/A> otherwise.
134 =item OPENSSL_CPU_INFO
136 The current OpenSSL cpu settings.
137 This is the current setting of the cpu capability flags. It is usually
138 automatically configured but may be set via an environment variable.
139 The value has the same syntax as the environment variable.
140 For x86 the string looks like C<CPUINFO: OPENSSL_ia32cap=0x123:0x456>.
141 Or C<CPUINFO: N/A> if not available, such as when configured with B<no-asm>.
145 For an unknown I<t>, the text C<not available> is returned.
147 OPENSSL_info() also returns different strings depending on I<t>:
151 =item OPENSSL_INFO_CONFIG_DIR
153 The configured C<OPENSSLDIR>, which is the default location for
154 OpenSSL configuration files.
156 =item OPENSSL_INFO_ENGINES_DIR
158 The configured C<ENGINESDIR>, which is the default location for
161 =item OPENSSL_INFO_MODULES_DIR
163 The configured C<MODULESDIR>, which is the default location for
164 dynamically loadable OpenSSL modules other than engines.
166 =item OPENSSL_INFO_DSO_EXTENSION
168 The configured dynamically loadable module extension.
170 =item OPENSSL_INFO_DIR_FILENAME_SEPARATOR
172 The separator between a directory specification and a filename.
173 Note that on some operating systems, this is not the same as the
174 separator between directory elements.
176 =item OPENSSL_INFO_LIST_SEPARATOR
178 The OpenSSL list separator.
179 This is typically used in strings that are lists of items, such as the
180 value of the environment variable C<$PATH> on Unix (where the
181 separator is C<:>) or C<%PATH%> on Windows (where the separator is
184 =item OPENSSL_INFO_CPU_SETTINGS
186 The current OpenSSL cpu settings.
187 This is the current setting of the cpu capability flags. It is usually
188 automatically configured but may be set via an environment variable.
189 The value has the same syntax as the environment variable.
190 For x86 the string looks like C<OPENSSL_ia32cap=0x123:0x456>.
194 For an unknown I<t>, NULL is returned.
196 =head1 BACKWARD COMPATIBILITY
198 For compatibility, some older macros and functions are retained or
200 They are all considered deprecated.
204 B<OPENSSL_VERSION_NUMBER> is a combination of the major, minor and
205 patch version into a single integer 0xMNN00PP0L, where:
211 is the number from B<OPENSSL_VERSION_MAJOR>, in hexadecimal notation
215 is the number from B<OPENSSL_VERSION_MINOR>, in hexadecimal notation
219 is the number from B<OPENSSL_VERSION_PATCH>, in hexadecimal notation
225 OpenSSL_version_num() returns the value of B<OPENSSL_VERSION_NUMBER>.
229 OPENSSL_version_major(), OPENSSL_version_minor() and OPENSSL_version_patch()
230 return the version number parts as integers.
232 OPENSSL_version_pre_release() and OPENSSL_version_build_metadata() return
233 the values of B<OPENSSL_VERSION_PRE_RELEASE> and
234 B<OPENSSL_VERSION_BUILD_METADATA> respectively as constant strings.
235 For any of them that is undefined, the empty string is returned.
237 OpenSSL_version() returns constant strings.
245 The macros and functions described here were added in OpenSSL 3.0,
246 with the exception of the L</BACKWARD COMPATIBILITY> ones.
