Fixes #13656. Right now all openssl commands use a NULL propq. This patch adds a possibility to specify a custom propq. The implementation follows the example of set_nameopt/get_nameopt. Various tools had to be modified to call app_get0_propq after it has been populated. Otherwise the -propquery has no effect. The tests then verify the -propquery affects the tool behaviour by requesting a non-existing property.

=head1 DESCRIPTION
|
|
|
|
OpenSSL is a cryptography toolkit implementing the Secure Sockets Layer (SSL
|
|
v2/v3) and Transport Layer Security (TLS v1) network protocols and related
|
|
cryptography standards required by them.
|
|
|
|
The B<openssl> program is a command line program for using the various
|
|
cryptography functions of OpenSSL's B<crypto> library from the shell.
|
|
It can be used for
|
|
|
|
o Creation and management of private keys, public keys and parameters
|
|
o Public key cryptographic operations
|
|
o Creation of X.509 certificates, CSRs and CRLs
|
|
o Calculation of Message Digests and Message Authentication Codes
|
|
o Encryption and Decryption with Ciphers
|
|
o SSL/TLS Client and Server Tests
|
|
o Handling of S/MIME signed or encrypted mail
|
|
o Timestamp requests, generation and verification
|
|
|
|
=head1 COMMAND SUMMARY
|
|
|
|
The B<openssl> program provides a rich variety of commands (I<command> in
|
|
the L</SYNOPSIS> above).
|
|
Each command can have many options and argument parameters, shown above as
|
|
I<options> and I<parameters>.
|
|
|
|
Detailed documentation and use cases for most standard subcommands are available
|
|
(e.g., L<openssl-x509(1)>).
|
|
|
|
The list options B<-standard-commands>, B<-digest-commands>,
|
|
and B<-cipher-commands> output a list (one entry per line) of the names
|
|
of all standard commands, message digest commands, or cipher commands,
|
|
respectively, that are available.
|
|
|
|
The list parameters B<-cipher-algorithms>, B<-digest-algorithms>,
|
|
and B<-mac-algorithms> list all cipher, message digest, and message
|
|
authentication code names, one entry per line. Aliases are listed as:
|
|
|
|
from => to
|
|
|
|
The list parameter B<-public-key-algorithms> lists all supported public
|
|
key algorithms.
|
|
|
|
The command B<no->I<XXX> tests whether a command of the
|
|
specified name is available. If no command named I<XXX> exists, it
|
|
returns 0 (success) and prints B<no->I<XXX>; otherwise it returns 1
|
|
and prints I<XXX>. In both cases, the output goes to B<stdout> and
|
|
nothing is printed to B<stderr>. Additional command line arguments
|
|
are always ignored. Since for each cipher there is a command of the
|
|
same name, this provides an easy way for shell scripts to test for the
|
|
availability of ciphers in the B<openssl> program. (B<no->I<XXX> is
|
|
not able to detect pseudo-commands such as B<quit>,
|
|
B<list>, or B<no->I<XXX> itself.)
|
|
|
|
=head2 Configuration Option
|
|
|
|
Many commands use an external configuration file for some or all of their
|
|
arguments and have a B<-config> option to specify that file.
|
|
The default name of the file is F<openssl.cnf> in the default certificate
|
|
storage area, which can be determined from the L<openssl-version(1)>
|
|
command using the B<-d> or B<-a> option.
|
|
The environment variable B<OPENSSL_CONF> can be used to specify a different
|
|
file location or to disable loading a configuration (using the empty string).
|
|
|
|
Among others, the configuration file can be used to load modules
|
|
and to specify parameters for generating certificates and random numbers.
|
|
See L<config(5)> for details.

See the L<openssl-passphrase-options(1)> manual page.
|
|
|
|
=head2 Random State Options
|
|
|
|
Prior to OpenSSL 1.1.1, it was common for applications to store information
|
|
about the state of the random-number generator in a file that was loaded
|
|
at startup and rewritten upon exit. On modern operating systems, this is
|
|
generally no longer necessary as OpenSSL will seed itself from a trusted
|
|
entropy source provided by the operating system. These flags are still
|
|
supported for special platforms or circumstances that might require them.
|
|
|
|
It is generally an error to use the same seed file more than once and
|
|
every use of B<-rand> should be paired with B<-writerand>.
|
|
|
|
=over 4
|
|
|
|
=item B<-rand> I<files>
|
|
|
|
A file or files containing random data used to seed the random number
|
|
generator.
|
|
Multiple files can be specified separated by an OS-dependent character.
|
|
The separator is C<;> for MS-Windows, C<,> for OpenVMS, and C<:> for
|
|
all others. Another way to specify multiple files is to repeat this flag
|
|
with different filenames.
|
|
|
|
=item B<-writerand> I<file>
|
|
|
|
Writes the seed data to the specified I<file> upon exit.
|
|
This file can be used in a subsequent command invocation.

=head2 Name Format Options
|
|
|
|
See the L<openssl-namedisplay-options(1)> manual page.
|
|
|
|
=head2 TLS Version Options
|
|
|
|
Several commands use SSL, TLS, or DTLS. By default, the commands use TLS and
|
|
clients will offer the lowest and highest protocol version they support,
|
|
and servers will pick the highest version that the client offers that is also
|
|
supported by the server.
|
|
|
|
The options below can be used to limit which protocol versions are used,
|
|
and whether TCP (SSL and TLS) or UDP (DTLS) is used.
|
|
Note that not all protocols and flags may be available, depending on how
|
|
OpenSSL was built.

These options require or disable the use of the specified SSL or TLS protocols.
|
|
When a specific TLS version is required, only that version will be offered or
|
|
accepted.
|

Only one specific protocol can be given and it cannot be combined with any of
|
|
the B<no_> options.

These options specify to use DTLS instead of DLTS.
|

With B<-dtls>, clients will negotiate any supported DTLS protocol version.
|

Use the B<-dtls1> or B<-dtls1_2> options to support only DTLS1.0 or DTLS1.2,
|

respectively.

=head2 Engine Options
|
|
|
|
=over 4
|
|
|
|
=item B<-engine> I<id>
|
|
|
|
Load the engine identified by I<id> and use all the methods it implements
|
|
(algorithms, key storage, etc.), unless specified otherwise in the
|
|
command-specific documentation or it is configured to do so, as described in
|
|
L<config(5)/Engine Configuration>.
|
|
|
|
The engine will be used for key ids specified with B<-key> and similar
|
|
options when an option like B<-keyform engine> is given.
|
|
|
|
A special case is the C<loader_attic> engine, which
|
|
is meant just for internal OpenSSL testing purposes and
|
|
supports loading keys, parameters, certificates, and CRLs from files.
|
|
When this engine is used, files with such credentials are read via this engine.
|
|
Using the C<file:> schema is optional; a plain file (path) name will do.
|
|
|
|
=back
|
|
|
|
Options specifying keys, like B<-key> and similar, can use the generic
|
|
OpenSSL engine key loading URI scheme C<org.openssl.engine:> to retrieve
|
|
private keys and public keys. The URI syntax is as follows, in simplified
|
|
form:
|
|
|
|
org.openssl.engine:{engineid}:{keyid}
|
|
|
|
Where C<{engineid}> is the identity/name of the engine, and C<{keyid}> is a
|
|
key identifier that's acceptable by that engine. For example, when using an
|
|
engine that interfaces against a PKCS#11 implementation, the generic key URI
|
|
would be something like this (this happens to be an example for the PKCS#11
|
|
engine that's part of OpenSC):
|
|
|
|
-key org.openssl.engine:pkcs11:label_some-private-key
|
|
|
|
As a third possibility, for engines and providers that have implemented
|
|
their own L<OSSL_STORE_LOADER(3)>, C<org.openssl.engine:> should not be
|
|
necessary. For a PKCS#11 implementation that has implemented such a loader,
|
|
the PKCS#11 URI as defined in RFC 7512 should be possible to use directly:
|
|
|
|
-key pkcs11:object=some-private-key;pin-value=1234
|

=head2 Provider Options

Also, it might not give you any output at all, depending on how

OpenSSL was built.

=head1 HISTORY
|
|
|
|
The B<list> -I<XXX>B<-algorithms> options were added in OpenSSL 1.0.0;
|
|
For notes on the availability of other commands, see their individual
|
|
manual pages.
|
|
|
|
The B<-issuer_checks> option is deprecated as of OpenSSL 1.1.0 and
|
|
is silently ignored.
|
|
|
|
The B<-xcertform> and B<-xkeyform> options
|
|
are obsolete since OpenSSL 3.0 and have no effect.
|
|
|
|
The interactive mode, which could be invoked by running C<openssl>
|
|
with no further arguments, was removed in OpenSSL 3.0, and running
|
|
that program with no arguments is now equivalent to C<openssl help>.
