✨ NAME ✨

okay bestie, this is openssl-ciphers from the 1ossl manual section — literally the SSL cipher display and cipher list command. It’s the page for converting textual OpenSSL cipher lists into ordered SSL cipher preference lists so you can figure out the appropriate cipherlist. 💅

🌸 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 💖

This command takes textual OpenSSL cipher lists and converts them into ordered SSL cipher preference lists. Basically: you give it cipher-list tea, and it gives you back the ordered preference list. It can be used to determine the appropriate cipherlist. ✨

🎀 OPTIONS 🎀

  • -help — prints a usage message. simple as that 🫶
  • -provider name — see "Provider Options" in openssl(1), provider(7), and property(7).
  • -provider-path path — see "Provider Options" in openssl(1), provider(7), and property(7).
  • -provparam [name:]key=value — see "Provider Options" in openssl(1), provider(7), and property(7).
  • -propquery propq — see "Provider Options" in openssl(1), provider(7), and property(7).
  • -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 -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.
    • 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. 🔑
  • -srp — when combined with -s, includes cipher suites which require SRP. This option is deprecated. 💀
  • -v — verbose output: for each cipher suite, list details as provided by SSL_CIPHER_description(3). 👀
  • -V — like -v, but include the official cipher suite values in hex. hex girlies rise 🔥
  • -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.
  • -stdname — precede each cipher suite by its standard name. ✨
  • -convert name — convert a standard cipher name to its OpenSSL name.
  • -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
  • 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. 🦋

🦋 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. ikyk 😌

The cipher string may reference a cipher using its standard name from the IANA TLS Cipher Suites Registry (https://www.iana.org/assignments/tls-parameters/tls-parameters.xhtml#tls-parameters-4).

The actual cipher string can take several different forms.

  • It can consist of a single cipher suite such as AES256-SHA.
  • 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.
  • 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.

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. gone forever, no cap 🫶
  • 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.
  • 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.
  • 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.

The cipher string @STRENGTH can be used at any point to sort the current cipher list in order of encryption algorithm key length. 💪

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.

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 the + character. For example, DEFAULT+AES is not valid. 🚫

The content of the default list is determined at compile time and normally corresponds to ALL:!COMPLEMENTOFDEFAULT:!eNULL.

🎀 CIPHER STRINGS 🎀

Okay bestie, this is the master list — every cipher string you're allowed to use and what it actually means. Think of it as the menu at the coolest restaurant in town ✨

  • COMPLEMENTOFDEFAULT — the cipher suites that are in ALL but not switched on by default. The default list is the safe-but-still-friendly starter pack: strong security, reasonable interoperability. A suite can get left off the default list for all kinds of reasons — it's weak, it's not "mature" enough yet, nobody really uses it, etc. Heads up tho: this string does not cover eNULL, because eNULL isn't in ALL at all (you want COMPLEMENTOFALL if you're brave enough to go there 👀).
  • ALL — literally all cipher suites except the eNULL ones (those you have to enable explicitly if you actually need them, which, why). As of OpenSSL 1.0.0 the ALL suites come sensibly ordered by default. Slay 💅.
  • COMPLEMENTOFALL — the suites that ALL doesn't switch on. Currently that's just eNULL. The leftovers 🍓.
  • HIGH — the "high" encryption cipher suites. Right now that means key lengths bigger than 128 bits, plus some suites with 128-bit keys.
  • MEDIUM — the "medium" encryption cipher suites. Currently some of the ones using 128-bit encryption.
  • LOW — the "low" encryption cipher suites: currently those using 64- or 56-bit encryption algorithms, but excluding export cipher suites. 💀 And plot twist: all of these have been removed as of OpenSSL 1.1.0. Gone. Ghosted. Not coming back.
  • FIPS — the cipher suites that are permitted in FIPS mode. Government-approved vibes 👑
  • eNULL, NULL — the "NULL" ciphers, meaning the ones offering no encryption whatsoever. Because that's zero encryption and honestly a whole security risk, they are not enabled by DEFAULT or by ALL. ⚠️ Be super careful when you build cipher lists out of lower-level primitives like kRSA or aECDSA — those lowkey overlap with the eNULL ciphers. When in doubt, just throw !eNULL in your cipher list. No cap.
  • 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 🙈. They're excluded from DEFAULT but included in ALL. ⚠️ Careful again when building lists from lower-level primitives like kDHE or AES — those overlap with aNULL too. When in doubt: !aNULL.
  • kRSA, aRSA, RSA — cipher suites using RSA key exchange, RSA authentication, or both of them, respectively.
  • kDHE, kEDH, DH — cipher suites using ephemeral DH key agreement, anonymous ones included.
  • 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) suites, iykyk.
  • kEECDH, kECDHE, ECDH — cipher suites using ephemeral ECDH key agreement, anonymous ones included.
  • ECDHE, EECDH — cipher suites using authenticated ephemeral ECDH key agreement.
  • AECDH — anonymous Elliptic Curve Diffie-Hellman cipher suites.
  • aDSS, DSS — cipher suites using DSS authentication, i.e. the certificates carry DSS keys.
  • aECDSA, ECDSA — cipher suites using ECDSA authentication, i.e. the certificates carry ECDSA keys.
  • TLSv1.2, TLSv1.0, SSLv3 — lists the 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 (she simply doesn't have her own). And because this is only the minimum version, if — say — TLSv1.0 gets negotiated, then both TLSv1.0 and SSLv3.0 cipher suites are available.
🫶 Important: these cipher strings do not change the negotiated version of SSL or TLS. They only affect the list of available cipher suites.
  • AES128, AES256, AES — cipher suites using 128-bit AES, 256-bit AES, or either 128 or 256-bit AES.
  • AESGCM — AES in Galois Counter Mode (GCM). These cipher suites are only supported in TLS v1.2.
  • AESCCM, AESCCM8 — AES in Cipher Block Chaining - Message Authentication Mode (CCM). 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 the 8 octet ICV.
  • ARIA128, ARIA256 — cipher suites using 128-bit ARIA or 256-bit ARIA respectively.
  • ARIA, ARIAGCM — cipher suites using either 128 or 256-bit ARIA.
  • CAMELLIA128, CAMELLIA256, CAMELLIA — cipher suites using 128-bit CAMELLIA, 256-bit CAMELLIA, or either 128 or 256-bit CAMELLIA.
  • CHACHA20 — cipher suites using ChaCha20. Periodt.
  • 3DES — cipher suites using triple DES.
  • DES — cipher suites using DES (not triple DES). All of these were removed in OpenSSL 1.1.0 💀 rip.
  • RC4 — cipher suites using RC4.
  • RC2 — cipher suites using RC2.
  • IDEA — cipher suites using IDEA.
  • SEED — cipher suites using SEED.
  • MD5 — cipher suites using MD5.
  • SHA1, SHA — cipher suites using SHA1.
  • SHA256, SHA384 — cipher suites using SHA256 or SHA384.
  • aGOST — cipher suites using GOST R 34.10 (either 2001 or 2012) for authentication. This one needs an engine supporting GOST algorithms, so plan accordingly.
  • aGOST01 — cipher suites that can be used with GOST R 34.10-2001 keys for authentication.
  • aGOST12 — cipher suites that can be used with GOST R 34.10-2012 keys for authentication.
  • kGOST — cipher suites using VKO 34.10 key exchange and key wrap specified in RFC 4357 or RFC 7836.
  • kGOST18 — cipher suites using VKO 34.10 key exchange specified in RFC 7836 and KExp15 key export specified in RFC 9189.
  • GOST94 — cipher suites using HMAC based on GOST R 34.11-94.
  • GOST12 — cipher suites using HMAC based on GOST R 34.11-2012 256 bits.
  • GOST89MAC — cipher suites using GOST 28147-89 MAC instead of HMAC, with S-boxes A.
  • GOST89MAC12 — cipher suites using GOST 28147-89 MAC instead of HMAC, with S-boxes Z.
  • GOST89 — cipher suites using any GOST cipher (GOST 28147-89, Magma or Kuznyechik).
  • PSK — all cipher suites using pre-shared keys (PSK). Come thru pre-shared keys 🗝️
  • kPSK, kECDHEPSK, kDHEPSK, kRSAPSK — cipher suites using PSK key exchange, ECDHE_PSK, DHE_PSK, or RSA_PSK.
  • aPSK — cipher suites using PSK authentication (currently all PSK modes apart from RSA_PSK).
  • kSRP, SRP — cipher suites using SRP key exchange.
  • aSRP — cipher suites using SRP authentication.
  • SUITEB128, SUITEB128ONLY, SUITEB192 — enables suite B mode of operation using 128 (permitting 192-bit mode by the peer), 128-bit (not permitting 192-bit by the peer), or 192-bit level of security respectively. ⚠️ If you use these cipherstrings they should appear first in the cipher list, and anything after them is ignored. Setting Suite B mode also has extra consequences required to comply with RFC6460 — specifically: the supported signature algorithms get 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. Big commitment, honestly.
  • CBC — all cipher suites using an encryption algorithm in Cipher Block Chaining (CBC) mode. These 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 🦋

So the lists that follow give you the standard SSL or TLS cipher suite names from the relevant spec, plus their OpenSSL equivalents. The bestie-approved part: you can use either standard names or OpenSSL names in cipher lists — or a lil mix of both 💖

One thing you should note, fr fr: several cipher suite names don't include the authentication being used — like DES-CBC3-SHA. In those cases, RSA authentication is what's being used. Okay so keep that in mind bestie — the lists are coming right up ✨

🌸 AES cipher suites for TLS v1.2 🌸

Okay bestie, buckle up, this is the big one — AES has so many suites, it's giving main character energy of the cipher world 👑. Every line is <official IANA name> on the left and the <OpenSSL name you actually type> on the right, so just read across, iykyk:

See how the OpenSSL names just drop the TLS_ and squish it? That's the whole pattern, bestie — you're basically a cipher-name girlie now 💅.

🍓 SEED cipher suites for TLS v1.2 🍓

SEED is the tiny baby section, only four (4) suites, lowkey adorable 🥺:

        TLS_DH_anon_WITH_SEED_CBC_SHA                  ADH-SEED-SHA
        TLS_DHE_DSS_WITH_SEED_CBC_SHA                  DHE-DSS-SEED-SHA
        TLS_DHE_RSA_WITH_SEED_CBC_SHA                  DHE-RSA-SEED-SHA
        TLS_RSA_WITH_SEED_CBC_SHA                      SEED-SHA

That's the whole list, periodt.

🧚 GOST cipher suites for TLS v1.2 🧚

⚠️ Heads up bestie: these ciphers require an engine which including GOST cryptographic algorithms, such as the gost engine, which isn't part of the OpenSSL distribution. So like... you can't just summon these out of nowhere, you gotta go get the engine yourself, and the gost engine is not shipped in the OpenSSL distribution 🙈.

The list, as-is:

        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

Notice the bottom chunk has no left-column IANA name — that's just how it is in here, don't come for me 😭 only the top two lines have that TLS_GOSTR341001_WITH_... counterpart.

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

🫶 Another lil note, and this one matters: the CBC modes mentioned in this RFC are not supported.

So like, RFC6209 mentions CBC modes, and OpenSSL is straight up not doing those — the CBC modes mentioned in that RFC are not supported. Noted, respected, moving on ✨.

⚠️ read this before you touch them: these ciphers are purely HMAC based and they provide zero confidentiality. like, none. they're disabled by default, and they're only available at security level 0. so if you're wondering why they're not showing up — that's why, and no you can't just vibe your way around it 🙈

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

these old name spellings are still accepted by older releases, purely so nothing breaks:

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

heads up bestie: some compiled versions of OpenSSL might not have every single cipher listed here, because some of them got excluded at compile time. so if one's missing from your build, it's not you, it's the build 🫶

💖 EXAMPLES

real talk, these are the ones you'll actually be copy-pasting. slay:

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) — and that's the deal 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.
