🌸 NAME 🌸

okay so you're reading openssl-ciphers(1ossl), aka openssl-ciphers — the SSL cipher display and cipher list command. bestie, this is the glow-up page for turning cipher lists into ordered preference lists 💅✨

✨ SYNOPSIS ✨

openssl ciphers [-help] [-s] [-v] [-V] [-ssl3] [-tls1] [-tls1_1]
[-tls1_2] [-tls1_3] [-psk] [-srp] [-stdname] [-convert name]
[-ciphersuites val] [-provider name] [-provider-path path] [-provparam
[name:]key=value] [-propquery propq] [cipherlist]

💖 DESCRIPTION 💖

so basically this command converts textual OpenSSL cipher lists into ordered SSL cipher preference lists. yes bestie, it's giving "figure out the appropriate cipherlist" energy 🌈

💅 OPTIONS 💅

-help — prints a usage message. short, sweet, iconic 🎀
-provider name, -provider-path path, -provparam [name:]key=value, -propquery propq — see "Provider Options" in openssl(1), provider(7), and property(7). it's all over there, iykyk 🫶
-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. very "real world" of it

PSK and SRP ciphers are not enabled by default: they require -psk or -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. server girlies have extra rules, no cap 💀

If this option is not used then all ciphers that match the cipherlist will be listed.

-psk — when combined with -s, includes cipher suites which require PSK. team-up option 🫶
-srp — when combined with -s, includes cipher suites which require SRP. this option is deprecated. yes bestie, deprecated, we said what we said 🙈
-v — verbose output: for each cipher suite, list details as provided by SSL_CIPHER_description(3). she's chatty and we love that 💬
-V — like -v, but include the official cipher suite values in hex. extra hex, extra slay 🔥
-tls1_3, -tls1_2, -tls1_1, -tls1, -ssl3 — in combination with the -s option, list the ciphers which could be used if the specified protocol were negotiated. note that not all protocols and flags may be available, depending on how OpenSSL was built. build-dependent behavior, classic 😭
-stdname — precede each cipher suite by its standard name. put some respect on the standard name 💅
-convert name — convert a standard cipher name to its OpenSSL name. translator era 🌐
-ciphersuites val — sets the list of TLSv1.3 ciphersuites. this list will be combined with any TLSv1.2 and below ciphersuites that have been configured. the format for this list is a simple colon (:) separated list of TLSv1.3 ciphersuite names. by default this value is:

TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256:TLS_AES_128_GCM_SHA256

literally the default trio, periodt 💜

cipherlist — a cipher list of TLSv1.2 and below ciphersuites to convert to a cipher preference list. this list will be combined with any TLSv1.3 ciphersuites that have been configured. if it is not included then the default cipher list will be used. the format is described below. yes bestie, keep reading 👇

🔐 CIPHER LIST FORMAT 🔐

the cipher list consists of one or more cipher strings separated by colons. commas or spaces are also acceptable separators but colons are normally used. colon supremacy, honestly 🎀

the cipher string may reference a cipher using its standard name from the IANA TLS Cipher Suites Registry — the link is literally https://www.iana.org/assignments/tls-parameters/tls-parameters.xhtml#tls-parameters-4. official registry behavior 👑

the actual cipher string can take several different forms.

it can consist of a single cipher suite such as AES256-SHA. one cipher, one moment, very main character ✨

it can represent a list of cipher suites containing a certain algorithm, or cipher suites of a certain type. for example SHA256 represents all cipher suites using the digest algorithm SHA256 and TLSv1.2 represents all cipher suites introduced in TLS v.1.2. algorithm-based grouping, we love a category 💖

lists of cipher suites can be combined in a single cipher string using the + character. this is used as a logical and operation. for example SHA256+AES represents all cipher suites using the SHA256 and the AES algorithms. and-operation but make it cute 🌸

each cipher string can be optionally preceded by the characters !, - or +.

if ! 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. permanent means permanent, no take-backs 💀
if - is used then the ciphers are deleted from the list, but some or all of the ciphers can be added again by later options. temporary removal, we can circle back 🦋
if + 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. it's giving rearranging the group chat, not adding new members 💅

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 be moved to the end of the list. no duplicates, no drama 🙈

the cipher string @STRENGTH can be used at any point to sort the current cipher list in order of encryption algorithm key length. sorting by key length is such a flex 🔥

the cipher string @SECLEVEL=n can be used at any point to set the security level to n, which should be a number between zero and five, inclusive. see SSL_CTX_set_security_level(3) for a description of what each level means. set the level, know the level, respect the level 💜

the cipher list can be prefixed with the DEFAULT keyword, which enables the default cipher list as defined below. unlike cipher strings, this prefix may not be combined with other strings using + character. for example, DEFAULT+AES is not valid. don't try it bestie, it's not that kind of party 😭

the content of the default list is determined at compile time and normally corresponds to ALL:!COMPLEMENTOFDEFAULT:!eNULL. compile-time default, iconic behavior 🎀

🌸 `COMPLEMENTOFDEFAULT` 🌸

The suites that are in ALL but not on by default. Lowkey the default list is already the good stuff — strong security, reasonable interoperability — and things get left off it for a bunch of reasons: they're weak, or not "mature" enough, or nobody really uses them, etc. 💅

Heads up bestie: this rule does not cover eNULL (that one isn't in ALL either — if you need it, that's what COMPLEMENTOFALL is for). 🫶

✨ `ALL` ✨

Every cipher suite except the eNULL ciphers (those have to be explicitly enabled if you actually want them, and you probably don't 👀). And as of OpenSSL 1.0.0, the ALL cipher suites come sensibly ordered by default — slay.

🎀 `COMPLEMENTOFALL` 🎀

The cipher suites that ALL does not enable. Currently that's eNULL. Periodt.

🔥 `HIGH` 🔥

"High" encryption cipher suites. Right now that means the ones with key lengths larger than 128 bits, plus some cipher suites with 128-bit keys. Main character energy only.

💜 `MEDIUM` 💜

"Medium" encryption cipher suites — currently some of the ones using 128 bit encryption.

🦋 `LOW` 🦋

"Low" encryption cipher suites — currently those using 64 or 56 bit encryption algorithms, but excluding export cipher suites.

💀 Okay so: all these cipher suites have been removed as of OpenSSL 1.1.0. They're gone bestie, not just ugly.

⭐ `FIPS` ⭐

Cipher suites permitted in FIPS mode.

🙈 `eNULL`, `NULL` 🙈

The "NULL" ciphers, aka the ones offering no encryption at all. Because they offer literally zero encryption and are a security risk, they are not enabled via either the DEFAULT or ALL cipher strings.

⚠️ Be careful when you're building cipherlists out of lower-level primitives like kRSA or aECDSA — those do overlap with the eNULL ciphers. When in doubt, throw !eNULL in your cipherlist. 💅

😭 `aNULL` 😭

The cipher suites offering no authentication. Currently that's the anonymous DH algorithms and anonymous ECDH algorithms. These are vulnerable to "man in the middle" attacks, so using them is discouraged, fr fr.

They're excluded from the DEFAULT ciphers but included in ALL. And same warning as above: when building cipherlists out of lower-level primitives like kDHE or AES, you can overlap with the aNULL ciphers — when in doubt, include !aNULL. 🫶

🔑 `kRSA`, `aRSA`, `RSA` 🔑

Cipher suites using RSA key exchange, RSA authentication, or both of them respectively. Respectively is doing so much work there, iykyk.

💫 `kDHE`, `kEDH`, `DH` 💫

Cipher suites using ephemeral DH key agreement — including anonymous cipher suites.

🌈 `DHE`, `EDH` 🌈

Cipher suites using authenticated ephemeral DH key agreement.

🧚 `ADH` 🧚

Anonymous DH cipher suites. Note that this does not include anonymous Elliptic Curve DH (ECDH) cipher suites. Read that again, bestie. ✨

👑 `kEECDH`, `kECDHE`, `ECDH` 👑

Cipher suites using ephemeral ECDH key agreement, including anonymous cipher suites.

🎀 `ECDHE`, `EECDH` 🎀

Cipher suites using authenticated ephemeral ECDH key agreement.

🌸 `aECDSA`, `ECDSA` 🌸

Cipher suites using ECDSA authentication — i.e. the certificates carry ECDSA keys.

⏳ `TLSv1.2`, `TLSv1.0`, `SSLv3` ⏳

Lists cipher suites introduced in TLS v1.2, TLS v1.0 or SSL v3.0 respectively.

Note: there are no cipher suites 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 cipher suites are available.

Note: these cipher strings do not change the negotiated version of SSL or TLS — they only affect the list of available cipher suites. Important distinction, don't get it twisted. 💀

🍓 `AES128`, `AES256`, `AES` 🍓

Cipher suites using 128 bit AES, 256 bit AES, or either 128 or 256 bit AES.

💜 `AESCCM`, `AESCCM8` 💜

AES in Cipher Block Chaining - Message Authentication Mode (CCM). These are only supported in TLS v1.2. AESCCM references CCM cipher suites using both 16 and 8 octet Integrity Check Value (ICV), while AESCCM8 only references 8 octet ICV. Tiny difference, big deal. ✨

🌈 `ARIA128`, `ARIA256` 🌈

Cipher suites using 128 bit ARIA or 256 bit ARIA respectively.

⭐ `ARIA`, `ARIAGCM` ⭐

Cipher suites using either 128 or 256 bit ARIA.

🇷🇺 `aGOST01` 🇷🇺

Cipher suites that can be uses with GOST R 34.10-2001 keys for authentication.

(yes "uses" — I'm quoting the energies here, don't come for me 💀)

👑 `SUITEB128`, `SUITEB128ONLY`, `SUITEB192` 👑

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 you use these, the cipherstrings should appear first in the cipher list, and anything after them is ignored. Like, literally ignored. Don't waste your time bestie.

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 cipher suites (ECDHE-ECDSA-AES128-GCM-SHA256 and ECDHE-ECDSA-AES256-GCM-SHA384) are permissible. She's picky. 💅

🧱 `CBC` 🧱

All cipher suites using encryption algorithm in Cipher Block Chaining (CBC) mode. These cipher suites are only supported in TLS v1.2 and earlier. Currently it's an alias for the following cipherstrings: SSL_DES, SSL_3DES, SSL_RC2, SSL_IDEA, SSL_AES128, SSL_AES256, SSL_CAMELLIA128, SSL_CAMELLIA256, SSL_SEED.

🎀 CIPHER SUITE NAMES 🎀

Okay so the following lists give you the standard SSL or TLS cipher suites names from the relevant specification, plus their OpenSSL equivalents. You can use either standard names or OpenSSL names in cipher lists — or a mix of both. Mix it up, slay. ✨

💡 It should be noted that several cipher suite names do not include the authentication used, e.g. DES-CBC3-SHA. In these cases, RSA authentication is used. So don't be confused when the auth isn't spelled out — assume RSA, bestie. 🫶

Okay so this is the big one bestie — the actual literal name-by-name dictionary of cipher suites, IANA name on the left, OpenSSL name on the right, and not one single line is getting skipped on my watch 😤 Every row is here, exactly as written, so you can ctrl-F your heart out 💖

Periodt. Four lines. No notes 💜

🧚 GOST cipher suites for TLS v1.2 🧚

Okay so real talk about the GOST ones, because there's a whole caveat here and you need to know it:

⚠️ These ciphers require an engine that includes GOST cryptographic algorithms, such as the gost engine — and that engine is not part of the OpenSSL distribution. So it's giving "you need to go get that yourself", bestie.

Here's the mapping:

TLS_GOSTR341001_WITH_28147_CNT_IMIT         GOST2001-GOST89-GOST89
TLS_GOSTR341001_WITH_NULL_GOSTR3411         GOST2001-NULL-GOST94
                                            IANA-GOST2012-GOST8912-GOST8912
                                            LEGACY-GOST2012-GOST8912-GOST8912
                                            GOST2012-NULL-GOST12
                                            GOST2012-KUZNYECHIK-KUZNYECHIKOMAC
                                            GOST2012-MAGMA-MAGMAOMAC

Yeah — see how some rows only have the right-hand column filled in? Those are OpenSSL-side names that don't get their own IANA left-hand entry in this list. That's just how it is, don't come for me, I'm reporting the facts 🫶

🌈 ARIA cipher suites from RFC6209, extending TLS v1.2 🌈

And finally (for this chunk anyway), ARIA, which comes to us from RFC6209 and extends TLS v1.2 🎀

🚨 Heads up though: the CBC modes mentioned in this RFC are not supported. So when you see CBC in that RFC, just know OpenSSL is not picking up what they're putting down. Not supported. Full stop.

Okay so the ARIA crew keeps going — same deal as before, full name on the left, the short version you can actually type on the right 💅

Vibe check 🌸 — those RC4 ones and the anon ones are giving legacy, bestie. But the page lists them, so the page lists them, and I'm not about to hide anything from you 💖

💖 Pre-shared keying (PSK) cipher suites 💖

okay bestie, this is the PSK squad — pre-shared keying cipher suites. Each row gives you two names side by side, and yes you keep both exactly as written. no renaming, no “fixing,” no cap. 🫶

🧚 TLS v1.3 integrity-only cipher suites according to RFC 9150 🧚

and here’s the integrity-only little duo from RFC 9150:

TLS_SHA256_SHA256          TLS_SHA256_SHA256
TLS_SHA384_SHA384          TLS_SHA384_SHA384

Note: these ciphers are purely HMAC based and do not provide any confidentiality and thus are disabled by default. These ciphers are only available at security level 0.

like… genuinely zero confidentiality, so do not treat these as your secret-keeping besties. 🫣

🫶 "EDH-" aliases to "DHE-" names for backward compatibility 🫶

The following names are accepted by older releases:

EDH-RSA-DES-CBC3-SHA — alias of DHE-RSA-DES-CBC3-SHA
EDH-DSS-DES-CBC3-SHA — alias of DHE-DSS-DES-CBC3-SHA

📝 NOTES 📝

Some compiled versions of OpenSSL may not include all the ciphers listed here because some ciphers were excluded at compile time. so if one’s missing, it’s giving compile-time choices, not a personal attack. 💀

🌸 EXAMPLES 🌸

okay, show-and-tell time — every command here is copied exactly, quotes and all. slay responsibly. 💖

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 AES ciphers and then place RSA ciphers last:

openssl ciphers -v 'AES:+RSA'

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'

🕰️ HISTORY 🕰️

The -V option was added in OpenSSL 1.0.0.
The -stdname is only available if OpenSSL is built with tracing enabled (enable-ssl-trace argument to Configure) before OpenSSL 1.1.1.
The -convert option was added in OpenSSL 1.1.1.
Support for standard IANA names in cipher lists was added in OpenSSL 3.2.0.
The support for TLS v1.3 integrity-only cipher suites was added in OpenSSL 3.4.
