Quick Start
-----------
$ mms test
$ mms install
+ on Windows (only pick one of the targets for configuration):
+
+ $ perl Configure { VC-WIN32 | VC-WIN64A | VC-WIN64I | VC-CE }
+ $ nmake
+ $ nmake test
+ $ nmake install
+
[If any of these steps fails, see section Installation in Detail below.]
This will build and install OpenSSL in the default location, which is:
Unix: normal installation directories under /usr/local
OpenVMS: SYS$COMMON:[OPENSSL-'version'...], where 'version' is the
- OpenSSL version number ('major'_'minor').
+ OpenSSL version number with underscores instead of periods.
+ Windows: C:\Program Files\OpenSSL or C:\Program Files (x86)\OpenSSL
If you want to install it anywhere else, run config like this:
---------------------
There are several options to ./config (or ./Configure) to customize
- the build:
-
- --prefix=DIR The top of the installation directory tree. Defaults are:
-
- Unix: /usr/local
- OpenVMS: SYS$COMMON:[OPENSSL-'version']
-
- --openssldir=DIR Directory for OpenSSL configuration files, and also the
- default certificate and key store. Defaults are:
-
- Unix: PREFIX/ssl (PREFIX is given by --prefix)
- OpenVMS: SYS$COMMON:[SSL]
-
- no-autoalginit Don't automatically load all supported ciphers and digests.
- Typically OpenSSL will make available all of its supported
- ciphers and digests. For a statically linked application this
- may be undesirable if small executable size is an objective.
- This only affects libcrypto. Ciphers and digests will have to be
- loaded manually using EVP_add_cipher() and EVP_add_digest() if
- this option is used.
-
- no-autoerrinit Don't automatically load all libcrypto/libssl error strings.
- Typically OpenSSL will automatically load human readable error
- strings. For a statically linked application this may be
- undesirable if small executable size is an objective.
-
- no-threads Don't try to build with support for multi-threaded
- applications.
-
- threads Build with support for multi-threaded applications.
- This will usually require additional system-dependent options!
- See "Note on multi-threading" below.
-
- no-zlib Don't try to build with support for zlib compression and
- decompression.
-
- zlib Build with support for zlib compression/decompression.
+ the build (note that for Windows, the defaults for --prefix and
+ --openssldir depend in what configuration is used and what Windows
+ implementation OpenSSL is built on. More notes on this in NOTES.WIN):
+
+ --prefix=DIR
+ The top of the installation directory tree. Defaults are:
+
+ Unix: /usr/local
+ Windows: C:\Program Files\OpenSSL
+ or C:\Program Files (x86)\OpenSSL
+ OpenVMS: SYS$COMMON:[OPENSSL-'version']
+
+ --openssldir=DIR
+ Directory for OpenSSL configuration files, and also the
+ default certificate and key store. Defaults are:
+
+ Unix: /usr/local/ssl
+ Windows: C:\Program Files\Common Files\SSL
+ or C:\Program Files (x86)\Common Files\SSL
+ OpenVMS: SYS$COMMON:[OPENSSL-COMMON]
+
+ --api=x.y.z
+ Don't build with support for deprecated APIs below the
+ specified version number. For example "--api=1.1.0" will
+ remove support for all APIS that were deprecated in OpenSSL
+ version 1.1.0 or below.
+
+ no-afalgeng
+ Don't build the AFALG engine. This option will be forced if
+ on a platform that does not support AFALG.
+
+ no-asm
+ Do not use assembler code. On some platforms a small amount
+ of assembler code may still be used.
+
+ no-async
+ Do not build support for async operations.
+
+ no-autoalginit
+ Don't automatically load all supported ciphers and digests.
+ Typically OpenSSL will make available all of its supported
+ ciphers and digests. For a statically linked application this
+ may be undesirable if small executable size is an objective.
+ This only affects libcrypto. Ciphers and digests will have to
+ be loaded manually using EVP_add_cipher() and
+ EVP_add_digest() if this option is used. This option will
+ force a non-shared build.
+
+ no-autoerrinit
+ Don't automatically load all libcrypto/libssl error strings.
+ Typically OpenSSL will automatically load human readable
+ error strings. For a statically linked application this may
+ be undesirable if small executable size is an objective.
+
+
+ no-capieng
+ Don't build the CAPI engine. This option will be forced if
+ on a platform that does not support CAPI.
+
+ no-cms
+ Don't build support for CMS features
+
+ no-comp
+ Don't build support for SSL/TLS compression. If this option
+ is left enabled (the default), then compression will only
+ work if the zlib or zlib-dynamic options are also chosen.
+
+ enable-crypto-mdebug
+ Build support for debugging memory allocated via
+ OPENSSL_malloc() or OPENSSL_zalloc().
- zlib-dynamic Like "zlib", but has OpenSSL load the zlib library dynamically
- when needed. This is only supported on systems where loading
- of shared libraries is supported. This is the default choice.
+ enable-crypto-mdebug-backtrace
+ As for crypto-mdebug, but additionally provide backtrace
+ information for allocated memory.
+ TO BE USED WITH CARE: this uses GNU C functionality, and
+ is therefore not usable for non-GNU config targets. If
+ your build complains about the use of '-rdynamic' or the
+ lack of header file execinfo.h, this option is not for you.
+ ALSO NOTE that even though execinfo.h is available on your
+ system (through Gnulib), the functions might just be stubs
+ that do nothing.
- no-shared Don't try to create shared libraries.
+ no-ct
+ Don't build support for Certificate Transparency.
- shared In addition to the usual static libraries, create shared
- libraries on platforms where it's supported. See "Note on
- shared libraries" below.
-
- no-asm Do not use assembler code.
-
- 386 On Intel hardware, use the 80386 instruction set only
- (the default x86 code is more efficient, but requires at
- least a 486). Note: Use compiler flags for any other CPU
- specific configuration, e.g. "-m32" to build x86 code on
- an x64 system.
-
- no-sse2 Exclude SSE2 code pathes. Normally SSE2 extension is
- detected at run-time, but the decision whether or not the
- machine code will be executed is taken solely on CPU
- capability vector. This means that if you happen to run OS
- kernel which does not support SSE2 extension on Intel P4
- processor, then your application might be exposed to
- "illegal instruction" exception. There might be a way
- to enable support in kernel, e.g. FreeBSD kernel can be
- compiled with CPU_ENABLE_SSE, and there is a way to
- disengage SSE2 code pathes upon application start-up,
- but if you aim for wider "audience" running such kernel,
- consider no-sse2. Both 386 and no-asm options above imply
- no-sse2.
-
- no-<cipher> Build without the specified cipher (bf, cast, des, dh, dsa,
- hmac, md2, md5, mdc2, rc2, rc4, rc5, rsa, sha).
- The crypto/<cipher> directory can be removed after running
- "make depend".
-
- -Dxxx, -lxxx, -Lxxx, -fxxx, -mXXX, -Kxxx These system specific options will
- be passed through to the compiler to allow you to
- define preprocessor symbols, specify additional libraries,
- library directories or other compiler options.
+ no-deprecated
+ Don't build with support for any deprecated APIs. This is the
+ same as using "--api" and supplying the latest version
+ number.
+
+ no-dgram
+ Don't build support for datagram based BIOs. Selecting this
+ option will also force the disabling of DTLS.
+
+ no-dso
+ Don't build support for loading Dynamic Shared Objects.
+
+ no-dynamic-engine
+ Don't build the dynamically loaded engines. This only has an
+ effect in a "shared" build
+
+ no-ec
+ Don't build support for Elliptic Curves.
+
+ no-ec2m
+ Don't build support for binary Elliptic Curves
+
+ enable-ec_nistp_64_gcc_128
+ Enable support for optimised implementations of some commonly
+ used NIST elliptic curves. This is only supported on some
+ platforms.
+
+ enable-egd
+ Build support for gathering entropy from EGD (Entropy
+ Gathering Daemon).
+
+ no-engine
+ Don't build support for loading engines.
+
+ no-err
+ Don't compile in any error strings.
+
+ no-filenames
+ Don't compile in filename and line number information (e.g.
+ for errors and memory allocation).
+
+ no-gost
+ Don't build support for GOST based ciphersuites. Note that
+ if this feature is enabled then GOST ciphersuites are only
+ available if the GOST algorithms are also available through
+ loading an externally supplied engine.
+
+ enable-heartbeats
+ Build support for DTLS heartbeats.
+
+ no-hw-padlock
+ Don't build the padlock engine.
+
+ no-makedepend
+ Don't generate dependencies.
+
+ no-multiblock
+ Don't build support for writing multiple records in one
+ go in libssl (Note: this is a different capability to the
+ pipelining functionality).
+
+ no-nextprotoneg
+ Don't build support for the NPN TLS extension.
+
+ no-ocsp
+ Don't build support for OCSP.
+
+ no-pic
+ Don't build with support for Position Independent Code.
+
+ no-posix-io
+ Don't use POSIX IO capabilities.
+
+ no-psk
+ Don't build support for Pre-Shared Key based ciphersuites.
+
+ no-rdrand
+ Don't use hardware RDRAND capabilities.
+
+ no-rfc3779
+ Don't build support for RFC3779 ("X.509 Extensions for IP
+ Addresses and AS Identifiers")
+
+ sctp
+ Build support for SCTP
+
+ no-shared
+ Do not create shared libraries, only static ones. See "Note
+ on shared libraries" below.
+
+ no-sock
+ Don't build support for socket BIOs
+
+ no-srp
+ Don't build support for SRP or SRP based ciphersuites.
+
+ no-srtp
+ Don't build SRTP support
+
+ no-sse2
+ Exclude SSE2 code paths. Normally SSE2 extension is
+ detected at run-time, but the decision whether or not the
+ machine code will be executed is taken solely on CPU
+ capability vector. This means that if you happen to run OS
+ kernel which does not support SSE2 extension on Intel P4
+ processor, then your application might be exposed to
+ "illegal instruction" exception. There might be a way
+ to enable support in kernel, e.g. FreeBSD kernel can be
+ compiled with CPU_ENABLE_SSE, and there is a way to
+ disengage SSE2 code pathes upon application start-up,
+ but if you aim for wider "audience" running such kernel,
+ consider no-sse2. Both the 386 and no-asm options imply
+ no-sse2.
+
+ enable-ssl-trace
+ Build with the SSL Trace capabilities (adds the "-trace"
+ option to s_client and s_server).
+
+ no-static-engine
+ Don't build the statically linked engines. This only
+ has an impact when not built "shared".
+
+ no-stdio
+ Don't use any C "stdio" features. Only libcrypto and libssl
+ can be built in this way. Using this option will suppress
+ building the command line applications. Additionally since
+ the OpenSSL tests also use the command line applications the
+ tests will also be skipped.
+
+ no-threads
+ Don't try to build with support for multi-threaded
+ applications.
+
+ threads
+ Build with support for multi-threaded applications. Most
+ platforms will enable this by default. However if on a
+ platform where this is not the case then this will usually
+ require additional system-dependent options! See "Note on
+ multi-threading" below.
+
+ no-ts
+ Don't build Time Stamping Authority support.
+
+ no-ui
+ Don't build with the "UI" capability (i.e. the set of
+ features enabling text based prompts).
+
+ enable-unit-test
+ Enable additional unit test APIs. This should not typically
+ be used in production deployments.
+
+ enable-weak-ssl-ciphers
+ Build support for SSL/TLS ciphers that are considered "weak"
+ (e.g. RC4 based ciphersuites).
+
+ zlib
+ Build with support for zlib compression/decompression.
+
+ zlib-dynamic
+ Like "zlib", but has OpenSSL load the zlib library
+ dynamically when needed. This is only supported on systems
+ where loading of shared libraries is supported.
+
+ 386
+ On Intel hardware, use the 80386 instruction set only
+ (the default x86 code is more efficient, but requires at
+ least a 486). Note: Use compiler flags for any other CPU
+ specific configuration, e.g. "-m32" to build x86 code on
+ an x64 system.
+
+ no-<prot>
+ Don't build support for negotiating the specified SSL/TLS
+ protocol (one of ssl, ssl3, tls, tls1, tls1_1, tls1_2, dtls,
+ dtls1 or dtls1_2). If "no-tls" is selected then all of tls1,
+ tls1_1 and tls1_2 are disabled. Similarly "no-dtls" will
+ disable dtls1 and dtls1_2. The "no-ssl" option is synonymous
+ with "no-ssl3". Note this only affects version negotiation.
+ OpenSSL will still provide the methods for applications to
+ explicitly select the individual protocol versions.
+
+ no-<prot>-method
+ As for no-<prot> but in addition do not build the methods for
+ applications to explicitly select individual protocol
+ versions.
+
+ enable-<alg>
+ Build with support for the specified algorithm, where <alg>
+ is one of: md2 or rc5.
+
+ no-<alg>
+ Build without support for the specified algorithm, where
+ <alg> is one of: bf, blake2, camellia, cast, chacha, cmac,
+ des, dh, dsa, ecdh, ecdsa, idea, md4, md5, mdc2, ocb,
+ ploy1305, rc2, rc4, rmd160, scrypt, seed or whirlpool. The
+ "ripemd" algorithm is deprecated and if used is synonymous
+ with rmd160.
+
+ -Dxxx, -lxxx, -Lxxx, -fxxx, -mXXX, -Kxxx
+ These system specific options will be passed through to the
+ compiler to allow you to define preprocessor symbols, specify
+ additional libraries, library directories or other compiler
+ options.
Installation in Detail
1a. Configure OpenSSL for your operation system automatically:
+ NOTE: This is not available on Windows.
+
$ ./config [options] # Unix
or
$ @[PATH.TO.OPENSSL.SOURCE]Configure {target} {options}
+ Windows example:
+
+ $ C:
+ $ mkdir \temp-openssl
+ $ cd \temp-openssl
+ $ perl d:\PATH\TO\OPENSSL\SOURCE\Configure {target} {options}
+
Paths can be relative just as well as absolute. Configure will
do its best to translate them to relative paths whenever possible.
$ make # Unix
$ mms ! (or mmk) OpenVMS
+ $ nmake # Windows
This will build the OpenSSL libraries (libcrypto.a and libssl.a on
Unix, corresponding on other platforms) and the OpenSSL binary
report the problem to <rt@openssl.org> (note that your message
will be recorded in the request tracker publicly readable at
https://www.openssl.org/community/index.html#bugs and will be
- forwarded to a public mailing list). Include the output of "make
- report" in your message. Please check out the request tracker. Maybe
- the bug was already reported or has already been fixed.
+ forwarded to a public mailing list). Please check out the request
+ tracker. Maybe the bug was already reported or has already been
+ fixed.
[If you encounter assembler error messages, try the "no-asm"
configuration option as an immediate fix.]
$ make test # Unix
$ mms test ! OpenVMS
+ $ nmake test # Windows
If some tests fail, look at the output. There may be reasons for
the failure that isn't a problem in OpenSSL itself (like a
malfunction with Perl). You may want increased verbosity, that
can be accomplished like this:
- $ HARNESS_VERBOSE=yes make test # Unix
+ $ make VERBOSE=1 test # Unix
- $ DEFINE HARNESS_VERBOSE YES
- $ mms test ! OpenVMS
+ $ mms /macro=(VERBOSE=1) test ! OpenVMS
+
+ $ nmake VERBOSE=1 test # Windows
If you want to run just one or a few specific tests, you can use
the make variable TESTS to specify them, like this:
$ make TESTS='test_rsa test_dsa' test # Unix
$ mms/macro="TESTS=test_rsa test_dsa" test ! OpenVMS
+ $ nmake TESTS='test_rsa test_dsa' test # Windows
And of course, you can combine (Unix example shown):
- $ HARNESS_VERBOSE=yes make TESTS='test_rsa test_dsa' test
+ $ make VERBOSE=1 TESTS='test_rsa test_dsa' test
You can find the list of available tests like this:
$ make list-tests # Unix
$ mms list-tests ! OpenVMS
+ $ nmake list-tests # Windows
Have a look at the manual for the perl module Test::Harness to
see what other HARNESS_* variables there are.
compiler optimization flags from the CFLAGS line in Makefile and
run "make clean; make" or corresponding.
- Please send a bug report to <openssl-bugs@openssl.org>, and when
- you do, please run the following and include the output in your
- report:
-
- $ make report
+ Please send a bug reports to <rt@openssl.org>.
4. If everything tests ok, install OpenSSL with

Note on shared libraries
------------------------
- Shared libraries have certain caveats. Binary backward compatibility
- can't be guaranteed before OpenSSL version 1.0. The only reason to
- use them would be to conserve memory on systems where several programs
- are using OpenSSL.
-
- For some systems, the OpenSSL Configure script knows what is needed to
- build shared libraries for libcrypto and libssl. On these systems,
- the shared libraries are currently not created by default, but giving
- the option "shared" will get them created. This method supports Makefile
- targets for shared library creation, like linux-shared. Those targets
- can currently be used on their own just as well, but this is expected
- to change in future versions of OpenSSL.
+ For most systems the OpenSSL Configure script knows what is needed to
+ build shared libraries for libcrypto and libssl. On these systems
+ the shared libraries will be created by default. This can be suppressed and
+ only static libraries created by using the "no-shared" option. On systems
+ where OpenSSL does not know how to build shared libraries the "no-shared"
+ option will be forced and only static libraries will be created.
