=head1 DESCRIPTION
|
|
|
|
The B<ciphers> command converts textual OpenSSL cipher lists into ordered
|
|
SSL cipher preference lists. It can be used as a test tool to determine
|
|
the appropriate cipherlist.
|
|
|
|
=head1 COMMAND OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item B<-help>
|
|
|
|
Print a usage message.
|
|
|
|
=item B<-s>
|
|
|
|
Only list supported ciphers: those consistent with the security level, and
|
|
minimum and maximum protocol version. This is closer to the actual cipher list
|
|
an application will support.
|
|
|
|
PSK and SRP ciphers are not enabled by default: they require B<-psk> or B<-srp>
|
|
to enable them.
|
|
|
|
It also does not change the default list of supported signature algorithms.
|
|
|
|
On a server the list of supported ciphers might also exclude other ciphers
|
|
depending on the configured certificates and presence of DH parameters.
|
|
|
|
If this option is not used then all ciphers that match the cipherlist will be
|
|
listed.
|
|
|
|
=item B<-psk>
|
|
|
|
When combined with B<-s> includes cipher suites which require PSK.
|
|
|
|
=item B<-srp>
|
|
|
|
When combined with B<-s> includes cipher suites which require SRP.
|
|
|
|
=item B<-v>
|
|
|
|
Verbose output: For each ciphersuite, list details as provided by
|
|
L<SSL_CIPHER_description(3)>.
|
|
|
|
=item B<-V>
|
|
|
|
Like B<-v>, but include the official cipher suite values in hex.
|
|
|
|
=item B<-tls1_2>

|
=item B<-tls1_1>
|
|
|
|
In combination with the B<-s> option, list the ciphers which would be used if

|
=item B<-stdname>
|
|
|
|
precede each ciphersuite by its standard name: only available is OpenSSL
|
|
is built with tracing enabled (B<enable-ssl-trace> argument to Configure).
|
|
|
|
=item B<cipherlist>
|
|
|
|
a cipher list to convert to a cipher preference list. If it is not included
|
|
then the default cipher list will be used. The format is described below.
|
|
|
|

|
|
|
|
=head1 CIPHER LIST FORMAT
|
|
|
|
The cipher list consists of one or more I<cipher strings> separated by colons.
|
|
Commas or spaces are also acceptable separators but colons are normally used.
|
|
|
|
The actual cipher string can take several different forms.
|
|
|
|
It can consist of a single cipher suite such as B<RC4-SHA>.
|
|
|
|
It can represent a list of cipher suites containing a certain algorithm, or
|
|
cipher suites of a certain type. For example B<SHA1> represents all ciphers
|
|
suites using the digest algorithm SHA1 and B<SSLv3> represents all SSL v3
|
|
algorithms.
|
|
|
|
Lists of cipher suites can be combined in a single cipher string using the
|
|
B<+> character. This is used as a logical B<and> operation. For example
|
|
B<SHA1+DES> represents all cipher suites containing the SHA1 B<and> the DES
|
|
algorithms.
|
|
|
|
Each cipher string can be optionally preceded by the characters B<!>,
|
|
B<-> or B<+>.
|
|
|
|
If B<!> is used then the ciphers are permanently deleted from the list.
|
|
The ciphers deleted can never reappear in the list even if they are
|
|
explicitly stated.
|
|
|
|
If B<-> is used then the ciphers are deleted from the list, but some or
|
|
all of the ciphers can be added again by later options.
|
|
|
|
If B<+> is used then the ciphers are moved to the end of the list. This
|
|
option doesn't add any new ciphers it just moves matching existing ones.
|
|
|
|
If none of these characters is present then the string is just interpreted
|
|
as a list of ciphers to be appended to the current preference list. If the
|
|
list includes any ciphers already present they will be ignored: that is they
|
|
will not moved to the end of the list.
|
|
|
|
The cipher string B<@STRENGTH> can be used at any point to sort the current
|
|
cipher list in order of encryption algorithm key length.
|
|
|
|
The cipher string B<@SECLEVEL=n> can be used at any point to set the security
|
|
level to B<n>.
|
|
|
|
=head1 CIPHER STRINGS
|
|
|
|
The following is a list of all permitted cipher strings and their meanings.
|
|
|
|
=over 4
|
|
|
|
=item B<DEFAULT>
|
|
|
|
The default cipher list.
|
|
This is determined at compile time and is normally
|
|
B<ALL:!COMPLEMENTOFDEFAULT:!eNULL>.
|
|
When used, this must be the first cipherstring specified.
|
|
|
|
=item B<COMPLEMENTOFDEFAULT>
|
|
|
|
The ciphers included in B<ALL>, but not enabled by default. Currently
|
|
this includes all RC4 and anonymous ciphers. Note that this rule does
|
|
not cover B<eNULL>, which is not included by B<ALL> (use B<COMPLEMENTOFALL> if
|
|
necessary). Note that RC4 based ciphersuites are not built into OpenSSL by
|
|
default (see the enable-weak-ssl-ciphers option to Configure).
|
|
|
|
=item B<ALL>
|
|
|
|
All cipher suites except the B<eNULL> ciphers (which must be explicitly enabled
|
|
if needed).
|
|
As of OpenSSL 1.0.0, the B<ALL> cipher suites are sensibly ordered by default.
|
|
|
|
=item B<COMPLEMENTOFALL>
|
|
|
|
The cipher suites not enabled by B<ALL>, currently B<eNULL>.
|
|
|
|
=item B<HIGH>
|
|
|
|
"high" encryption cipher suites. This currently means those with key lengths
|
|
larger than 128 bits, and some cipher suites with 128-bit keys.
|
|
|
|
=item B<MEDIUM>
|
|
|
|
"medium" encryption cipher suites, currently some of those using 128 bit
|
|
encryption.
|
|
|
|
=item B<LOW>
|
|
|
|
"low" encryption cipher suites, currently those using 64 or 56 bit
|
|
encryption algorithms but excluding export cipher suites. All these
|
|
ciphersuites have been removed as of OpenSSL 1.1.0.
|
|
|
|
=item B<eNULL>, B<NULL>
|
|
|
|
The "NULL" ciphers that is those offering no encryption. Because these offer no
|
|
encryption at all and are a security risk they are not enabled via either the
|
|
B<DEFAULT> or B<ALL> cipher strings.
|
|
Be careful when building cipherlists out of lower-level primitives such as
|
|
B<kRSA> or B<aECDSA> as these do overlap with the B<eNULL> ciphers. When in
|
|
doubt, include B<!eNULL> in your cipherlist.
|
|
|
|
=item B<aNULL>
|
|
|
|
The cipher suites offering no authentication. This is currently the anonymous
|
|
DH algorithms and anonymous ECDH algorithms. These cipher suites are vulnerable
|
|
to "man in the middle" attacks and so their use is discouraged.
|
|
These are excluded from the B<DEFAULT> ciphers, but included in the B<ALL>
|
|
ciphers.
|
|
Be careful when building cipherlists out of lower-level primitives such as
|
|
B<kDHE> or B<AES> as these do overlap with the B<aNULL> ciphers.
|
|
When in doubt, include B<!aNULL> in your cipherlist.
|
|
|
|
=item B<kRSA>, B<aRSA>, B<RSA>
|
|
|
|
Cipher suites using RSA key exchange, authentication or either respectively.
|
|
|
|
=item B<kDHr>, B<kDHd>, B<kDH>
|
|
|
|
Cipher suites using static DH key agreement and DH certificates signed by CAs
|
|
with RSA and DSS keys or either respectively.
|
|
All these cipher suites have been removed in OpenSSL 1.1.0.
|
|
|
|
=item B<kDHE>, B<kEDH>, B<DH>
|
|
|
|
Cipher suites using ephemeral DH key agreement, including anonymous cipher
|
|
suites.
|
|
|
|
=item B<DHE>, B<EDH>
|
|
|
|
Cipher suites using authenticated ephemeral DH key agreement.
|
|
|
|
=item B<ADH>
|
|
|
|
Anonymous DH cipher suites, note that this does not include anonymous Elliptic
|
|
Curve DH (ECDH) cipher suites.
|
|
|
|
=item B<kEECDH>, B<kECDHE>, B<ECDH>
|
|
|
|
Cipher suites using ephemeral ECDH key agreement, including anonymous
|
|
cipher suites.
|
|
|
|
=item B<ECDHE>, B<EECDH>
|
|
|
|
Cipher suites using authenticated ephemeral ECDH key agreement.
|
|
|
|
=item B<AECDH>
|
|
|
|
Anonymous Elliptic Curve Diffie Hellman cipher suites.
|
|
|
|
=item B<aDSS>, B<DSS>
|
|
|
|
Cipher suites using DSS authentication, i.e. the certificates carry DSS keys.
|
|
|
|
=item B<aDH>
|
|
|
|
Cipher suites effectively using DH authentication, i.e. the certificates carry
|
|
DH keys.
|
|
All these cipher suites have been removed in OpenSSL 1.1.0.
|
|
|
|
=item B<aECDSA>, B<ECDSA>
|
|
|
|
Cipher suites using ECDSA authentication, i.e. the certificates carry ECDSA
|
|
keys.
|
|
|
|
=item B<TLSv1.2>, B<TLSv1.0>, B<SSLv3>
|
|
|
|
Lists ciphersuites which are only supported in at least TLS v1.2, TLS v1.0 or
|
|
SSL v3.0 respectively.
|
|
Note: there are no ciphersuites specific to TLS v1.1.
|
|
Since this is only the minimum version, if, for example, TLSv1.0 is negotiated
|
|
then both TLSv1.0 and SSLv3.0 ciphersuites are available.
|
|
|
|
Note: these cipher strings B<do not> change the negotiated version of SSL or
|
|
TLS, they only affect the list of available cipher suites.
|
|
|
|
=item B<AES128>, B<AES256>, B<AES>

|
|
ciphersuites are only supported in TLS v1.2. B<AESCCM> references CCM
|
|

|
=item B<SHA256>, B<SHA384>
|
|
|
|
Ciphersuites using SHA256 or SHA384.
|
|
|
|
=item B<aGOST>
|
|
|
|
Cipher suites using GOST R 34.10 (either 2001 or 94) for authentication
|
|
(needs an engine supporting GOST algorithms).
|
|
|
|
=item B<aGOST01>
|

|
|
|
|
Enables suite B mode of operation using 128 (permitting 192 bit mode by peer)
|
|
128 bit (not permitting 192 bit by peer) or 192 bit level of security
|
|
respectively.
|
|
If used these cipherstrings should appear first in the cipher
|
|
list and anything after them is ignored.
|
|
Setting Suite B mode has additional consequences required to comply with
|
|
RFC6460.
|
|
In particular the supported signature algorithms is reduced to support only
|
|
ECDSA and SHA256 or SHA384, only the elliptic curves P-256 and P-384 can be

|
used and only the two suite B compliant ciphersuites
|

(ECDHE-ECDSA-AES128-GCM-SHA256 and ECDHE-ECDSA-AES256-GCM-SHA384) are
|
|
permissible.

=head1 NOTES
|
|
|
|
Some compiled versions of OpenSSL may not include all the ciphers
|
|
listed here because some ciphers were excluded at compile time.
|
|
|
|
=head1 EXAMPLES
|
|
|
|
Verbose listing of all OpenSSL ciphers including NULL ciphers:
|
|
|
|
openssl ciphers -v 'ALL:eNULL'
|
|
|
|
Include all ciphers except NULL and anonymous DH then sort by
|
|
strength:
|
|
|
|
openssl ciphers -v 'ALL:!ADH:@STRENGTH'
|
|
|
|
Include all ciphers except ones with no encryption (eNULL) or no
|
|
authentication (aNULL):
|
|
|
|
openssl ciphers -v 'ALL:!aNULL'
|
|
|
|
Include only 3DES ciphers and then place RSA ciphers last:
|
|
|
|
openssl ciphers -v '3DES:+RSA'
|
|
|
|
Include all RC4 ciphers but leave out those without authentication:
|
|
|
|
openssl ciphers -v 'RC4:!COMPLEMENTOFDEFAULT'
|
|
|
|
Include all ciphers with RSA authentication but leave out ciphers without
|
|
encryption.
|
|
|
|
openssl ciphers -v 'RSA:!COMPLEMENTOFALL'
|
|
|
|
Set security level to 2 and display all ciphers consistent with level 2:
|
|
|
|
openssl ciphers -s -v 'ALL:@SECLEVEL=2'
|
