Those use PSA APIs unconditionally. +- The `USE_PSA` domain (that is, code that calls PSA crypto APIs when + `USE_PSA` is enabled, and legacy crypto APIs otherwise): that's PK, X.509, +most of TLS 1.2 and the parts of TLS 1.3 that are common with TLS 1.2 or are +about public/private keys (see `docs/use-psa-crypto.md` for details). +- The legacy crypto domain: a number of modules there will use crypto from + other modules, for example RSA and entropy will use hashes, PEM will use +hashes and ciphers (from encrypted PEM), etc. + +The first two categories (PSA domain, pure TLS 1.3 domain) are simple: as a +general rule, use `PSA_WANT` macros. (With very few exceptions, see +`component_check_test_dependencies` in `all.sh`.) In the rare instances where it is necessary to +check whether a mechanism is built-in or provided by a driver, +`MBEDTLS_PSA_BUILTIN_xxx` and `MBEDTLS_PSA_ACCEL_xxx` macros should be used +(but not legacy `MBEDTLS_xxx` macros). + +For the `USE_PSA` domain, it should always be correct to use expressions like +`(!USE_PSA && MBEDTLS_xxx) || (USE_PSA && PSA_WANT_xxx)`. Sometimes, macros +are defined in order to avoid using long expressions everywhere; they will be +mentioned in the following sections. + +The remaining category, the legacy domain, tends to be more complex. There are +different rules for different families of mechanisms, as detailed in the +following sections. + +Symmetric crypto +================ + +Hashes +------ + +**Hash vs HMAC:** Historically (since 2.0) we've had the generic hash +interface, and the implementation of HMAC, in the same file controlled by a +single feature macro: `MBEDTLS_MD_C`. This has now been split in two: +- `MBEDTLS_MD_LIGHT` is about the generic hash interface; we could think of it + as `MBEDTLS_HASH_C`. +- `MBEDTLS_MD_C` is about the HMAC implementation; we could think of it as + `MBEDTLS_HMAC_C` (auto-enabling `MBEDTLS_HASH_C`). + +(In fact, this is not the whole story: `MD_LIGHT` is the _core_ of the generic +hash interface, excluding functions such as `mbedtls_md_list()` and +`mbedtls_md_info_from_string()`, `mbedtls_md_file()`, etc. But I think the +above should still provide a good intuition as first approximation.) + +Note that all users of hashes in the library use either the PSA Crypto API or the `md.h` API. +That is, no user in the library, even in the legacy domain, uses the low-level hash APIs +(`mbedtls_sha256` etc). (That's not true of all example programs, though.) + +**Helper macros:** in `config_adjust_legacy_crypto.h` we define a family of +macro `MBEDTLS_MD_CAN_xxx`. These macros are defined (for available hashes) as +soon as `MBEDTLS_MD_LIGHT` is enabled. This subset of `MD` is automatically +enabled as soon as something from the legacy domain, or from the `USE_PSA` +domain, needs a hash. (Note that this includes `ENTROPY_C`, so in practice +`MD_LIGHT` is enabled in most builds.) + +Note that there is a rule, enforced by `config_adjust_psa_superset_legacy.h`, +that as soon as `PSA_CRYPTO_C` is enabled, all hashes that are enabled on the +legacy side are also enabled on the PSA side (the converse is not true: a hash +that's provided by a driver will typically be available only on the PSA side). So, in +practice, when `PSA_CRYPTO_C` and `MD_LIGHT` are both enabled, +`PSA_WANT_ALG_xxx` and `MBEDTLS_MD_CAN_xxx` are equivalent. + +**Legacy and `USE_PSA` domains:** for hashes, `MBEDTLS_MD_CAN_xxx` (where +`xxx` is the legacy name of the hash) can be used everywhere (except in the +PSA domain which should use `PSA_WANT` as usual). No special include is +required, `build_info.h` or `common.h` is enough. + +**Pure TLS 1.3 domain:** it is not easy to know which uses of hashes fall in +this domain as opposed to the `USE_PSA` domain whithout looking at the code. +Fortunately, `MD_CAN` and `PSA_WANT` macros can be used interchangeably, as +per the note above. + +HMAC +---- + +**Legacy domain:** the code is using the `md.h` API. For this domain, +availability of HMAC-xxx is determined by `MBEDTLS_MD_C && MBEDTLS_MD_CAN_xxx` +(see previous subsection about `MD_CAN`). Modules in this domain that may use +HMAC are PKCS5, PKCS7, HKDF, HMAC-DRBG and ECDSA deterministic. + +**`USE_PSA` domain:** code will use the `md.h` API when `USE_PSA` is disabled, +and the `psa_mac` API when `USE_PSA` is enabled. It should check for the +availability of HMAC-xxx with either: +``` +((!MBEDTLS_USE_PSA_CRYPTO && MBEDTLS_MD_C) || + (MBEDTLS_USE_PSA_CRYPTO && PSA_WANT_ALG_HMAC)) && +MBEDTLS_MD_CAN_xxx +``` +or +``` +(!MBEDTLS_USE_PSA_CRYPTO && MBEDTLS_MD_C && MBEDTLS_xxx_C) || +(MBEDTLS_USE_PSA_CRYPTO && PSA_WANT_ALG_HMAC && PSA_WANT_ALG_xxx) +``` +or any equivalent condition (see note at the end of the previous section). +The only module in this case is TLS, which currently depends on +`USE_PSA_CRYPTO || MD_C`. + +Note: while writing this, it occurs to me that TLS 1.2 does not seem to be +checking for `PSA_WANT_ALG_HMAC` before enabling CBC ciphersuites when +`USE_PSA` is enabled, which I think it should. Builds with `USE_PSA` enabled, +`PSA_WANT_ALG_HMAC` disabled and other requirements for CBC ciphersuites +enabled, are probably broken (perhaps only at runtime when a CBC ciphersuite +is negotiated). + +**Pure TLS 1.3 domain:** HMAC is used for the Finished message via PSA Crypto +APIs. So, TLS 1.3 should depend on `PSA_WANT_ALG_HMAC` - doesn't seem to be +enforced by `check_config.h`, or documented in `mbedtls_config.h`, at the +moment. + +Ciphers (AEAD and unauthenticated) +---------------------------------- + +**Overview of existing (internal) APIs:** we currently have 5 (families of) +APIs for ciphers (and associated constructs) in the library: +- Low-level API for primitives: `mbedtls_aes_xxx` etc. - used by `cipher.c` + and some other modules in the legacy domain. +- Internal abstraction layer `block_cipher` for AES, ARIA and Camellia + primitives - used only by `gcm.c` and `ccm.c`, only when `CIPHER_C` is not +enabled (for compatibility reasons). +- Block cipher modes / derivatives: + - `mbedtls_gcm_xxx` and `mbedtls_ccm_xxx`, used by `cipher.c` and + the built-in PSA implementation; + - `mbedtls_nist_kw_xxx`, used by `cipher.c`; + - `mbedtls_cipher_cmac_xxx`, used by the built-in PSA implementation; + - `mbedtls_ctr_drbg_xxx`, used by PSA crypto's RNG subsystem. +- Cipher: used by some modules in the legacy domain, and by the built-in PSA + implementation. +- PSA: used by the `USE_PSA` domain when `MBEDTLS_USE_PSA_CRYPTO` is enabled. + +**Legacy domain:** most code here is using either `cipher.h` or low-level APIs +like `aes.h`, and should use legacy macros like `MBEDTLS_AES_C` and +`MBEDTLS_CIPHER_MODE_CBC`. This includes NIST-KW, CMAC, PKCS5/PKCS12 en/decryption +functions, PEM decryption, PK parsing of encrypted keys. The only exceptions +are: +1. `GCM` and `CCM` use the internal abstraction layer `block_cipher` and check + for availability of block ciphers using `MBEDTLS_CCM_GCM_CAN_xxx` macros +defined in `config_adjut_legacy_crypto.h`. As a user, to check if AES-GCM is +available through the `mbedtls_gcm` API, you want to check for `MBEDTLS_GCM_C` +and `MBDTLS_CCM_GCM_CAN_AES`. +2. `CTR_DRBG` uses the low-level `mbedtls_aes_` API if it's available, + otherwise it uses the PSA API. There is no need for users of `CTR_DRBG` to +check if AES is available: `check_config.h` is already taking care of that, so +from a user's perspective as soon as `MBEDTLS_CTR_DRBG_C` is enabled, you can +use it without worrying about AES. + +**`USE_PSA` domain:** here we should use conditions like the following in +order to test for availability of ciphers and associated modes. +``` +// is AES available? +(!defined(MBEDTLS_USE_PSA_CRYPTO) && defined(MBEDTLS_AES_C)) || \ +(defined(MBEDTLS_USE_PSA_CRYPTO) && defined(PSA_WANT_KEY_TYPE_AES)) +// is CBC available? +(!defined(MBEDTLS_USE_PSA_CRYPTO) && defined(MBEDTLS_CIPHER_MODE_CBC)) || \ +(defined(MBEDTLS_USE_PSA_CRYPTO) && defined(PSA_WANT_ALG_CBC_NO_PADDING)) +// is GCM available? +(!defined(MBEDTLS_USE_PSA_CRYPTO) && defined(MBEDTLS_GCM_C)) || \ +(defined(MBEDTLS_USE_PSA_CRYPTO) && defined(PSA_WANT_ALG_GCM)) +``` +Note: TLS is the only user of ciphers in the `USE_PSA` domain, and it defines +`MBEDTLS_SSL_HAVE_xxx` macros in `config_adjust_legacy_crypto.h` for the +ciphers and modes it needs to know about. + +**Pure TLS 1.3 domain:** none. All from TLS 1.3 are in the `USE_PSA` domain +(common to TLS 1.2). + +Key derivation +-------------- + +**Legacy domain:** the modules PKCS5 and PKCS12 both provide +key derivation (respectively PBKDF2-HMAC and PKCS12 derivation), and use it +for password-based encryption. (Note: PEM has an implementation of PBKDF1 but +it's internal.) + +**`USE_PSA` domain:** PK (parse) will use PKCS5 and PKCS12 encryption (hence +indirectly key derivation) if present in the build. The macros are +`MBEDTLS_PKCS5_C` and `MBEDTLS_PKCS12_C`. Note that even when `USE_PSA` is +enabled, PK parse will _not_ use PSA for the PBKDF2 part of PKCS5 decryption. + +**Pure TLS 1.3 domain:** TLS 1.3 is using HKDF via PSA Crypto APIs. We already +enforce in `check_config.h` that TLS 1.3 depends on the appropriate `PSA_WANT` +macros. + +Asymmetric crypto +================= + +RSA +--- + +**Legacy domain and `USE_PSA` domain:** use `RSA_C` everywhere. (Note: there's +no user of RSA in the legacy domain, and the only direct user in the `USE_PSA` +domain is PK - both X.509 and TLS will only RSA via PK.) + +**Pure TLS 1.3 domain:** no use of RSA in this domain. All TLS 1.3 uses of RSA +go through PK, hence are in the `USE_PSA` domain. + +FFDH +---- + +**Legacy domain and `USE_PSA` domain:** use `DHM_C`. The only user is TLS 1.2 +which is actually in the legacy domain - this is an exception where `USE_PSA` +has no effect, because PSA doesn't cover the needs of TLS 1.2 here. + +**Pure TLS 1.3 domain:** use `PSA_WANT`. The TLS 1.3 code for Diffie-Hellman +is common to ECDH and FFDH thanks to PSA Crypto APIs being generic enough. The +parts about FFDH are guarded with `PSA_WANT_ALG_FFDH` (with the reasoning that +this implies support for the corresponding key type). + +ECC +--- + +**Curves:** in `config_adjut_psa_superset_legacy.h` we ensure that, as soon as +`PSA_CRYPTO_C` is enabled, all +curves that are supported on the legacy side (`MBEDTLS_ECP_DP_xxx_ENABLED`) +are also supported on the PSA side (`PSA_WANT_ECC_xxx`). (The converse is not +true as a curve provided by a driver will typically only be available on the +PSA side). + +In `config_adjust_legacy_crypto.h` we define macros `MBEDTLS_ECP_HAVE_xxx`. +These macros are useful for data and functions that have users in several +domains, such as `mbedtls_ecc_group_to_psa()`, or that have users only in the +`USE_PSA` domain but want a simpler (if sub-optimal) condition, such as +`mbedtls_oid_get_ec_grp()`. + +Strictly speaking, code in the `USE_PSA` domain should not use the above +`MBEDTLS_ECP_HAVE_xxx` macros but conditions like +``` +(!MBEDTLS_USE_PSA_CRYPTO && MBEDTLS_ECP_DP_xxx_ENABLED) || +(MBEDTLS_USE_PSA_CRYPTO && PSA_WANT_ECC_xxx) +``` +Note while writing: a lot of tests for things in the `USE_PSA` domain appear +to be using `MBEDTLS_ECP_HAVE_xxx`. IMO this is incorrect, but not caught by +the CI because I guess we don't run tests in configurations that have both +`USE_PSA_CRYPTO` disabled, and some curves enabled only on the PSA side. My +initial feeling is we don't care about such configurations as this point, and +can leave the dependencies as they are until they're replaced with `PSA_WANT` +macros in 4.0 anyway. + +**Legacy domain:** use the legacy macros `ECP_C`, `ECDH_C`, `ECDSA_C`, +`ECJPAKE_C`, `MBEDTLS_ECP_DP_xxx_ENABLED`. (This is mostly just ECDH, ECDSA +and EC J-PAKE using ECP.) + +**Key management, `USE_PSA` domain:** `MBEDTLS_PK_HAVE_ECC_KEYS` means that PK +supports ECC key parsing and writing (and storage). It does not imply support +for doing crypto operation with such keys - see `MBEDTLS_PK_CAN_ECDSA_xxx` +above for that. + +**ECDH, `USE_PSA` domain:** this is just TLS 1.2. It's using the helper macro +`MBEDTLS_CAN_ECDH` defined in `config_adjust_legacy_crypto.h` (which should +probably be called `MBEDTLS_SSL_TLS1_2_CAN_ECDH` as it's only for TLS 1.2). +(Note: the macro is not used directly in the code, it's only used as a +dependency for relevant TLS 1.2 key exchanges. Then the code uses the guards +for the key exchanges.) + +**ECDH, pure TLS 1.3 domain:** using `PSA_WANT_ALG_ECDH`. + +**ECDSA, `USE_PSA` domain:** should use the macros +`MBEDTLS_PK_CAN_ECDSA_{SIGN,VERIFY,SOME}` that indicate support for signature +generation, verification, or at least one of those, respectively. To check for +support for signatures with a specific hash, combine +`MBEDTLS_PK_CAN_ECDSA_xxx` with `MBEDTLS_MD_CAN_xxx`. + +**ECDSA, pure TLS 1.3 domain:** none - everything goes through PK. + +**EC J-PAKE, `USE_PSA` domain:** only used by TLS 1.2. The code is guarded by +the corresponding `KEY_EXCHANGE` macro, which in `check_config.h` depends on +the appropriate macros depending on whether `USE_PSA` is on or off. + +**EC J-PAKE, pure TLS 1.3 domain:** none - EC J-PAKE is TLS 1.2 (so far). + +**Related internal macros:** +- `MBEDTLS_PK_USE_PSA_EC_DATA` is an internal switch of the PK module. When + it's not defined, PK stores ECC keys as a `struct mbedtls_ecxxx_keypair`; +when it's defined, PK stores in a PSA -friendly format instead (PSA key slot +for private keys, metadata + array of bytes with the PSA import/export format +for the public part). This macro is only defined when `ECP_C` is not and +`USE_PSA` is, see comments above its definition in `pk.h` for details. +- `MBEDTLS_ECP_LIGHT` enables only a subset of `ecp.c`. This subset is pretty + much ad hoc: it's basically everything that doesn't depend on scalar +multiplication (_the_ complex expensive operation in ECC arithmetic). +Basically, this subset gives access to curve data (constants), key storage, +basic parsing and writing. It is auto-enabled in some driver-only +configurations where the user has disabled `ECP_C` because they have drivers +for the crypto operations they use, but they've also asked for some things +that are not supported by drivers yet, such as deterministic key derivation, +or parsing of compressed keys - on those cases, `ECP_LIGHT` will support this +needs without bringing back the full `ECP_C`. diff --git a/docs/driver-only-builds.md b/docs/driver-only-builds.md index 5d950b068d..6bd92623a1 100644 --- a/docs/driver-only-builds.md +++ b/docs/driver-only-builds.md @@ -408,8 +408,6 @@ Note that the relationship between legacy (i.e. `MBEDTLS_xxx_C`) and PSA ### Partial acceleration for CCM/GCM -[This section depends on #8598 so it might be updated while that PR progresses.] - In case legacy CCM/GCM algorithms are enabled, it is still possible to benefit from PSA acceleration of the underlying block cipher by enabling support for ECB mode (`PSA_WANT_ALG_ECB_NO_PADDING` + `MBEDTLS_PSA_ACCEL_ALG_ECB_NO_PADDING`) diff --git a/library/ssl_tls12_client.c b/library/ssl_tls12_client.c index 9b2da5a39d..75783d08f1 100644 --- a/library/ssl_tls12_client.c +++ b/library/ssl_tls12_client.c @@ -1964,7 +1964,7 @@ static int ssl_write_encrypted_pms(mbedtls_ssl_context *ssl, ssl->out_msg + offset + len_bytes, olen, MBEDTLS_SSL_OUT_CONTENT_LEN - offset - len_bytes, ssl->conf->f_rng, ssl->conf->p_rng)) != 0) { - MBEDTLS_SSL_DEBUG_RET(1, "mbedtls_rsa_pkcs1_encrypt", ret); + MBEDTLS_SSL_DEBUG_RET(1, "mbedtls_pk_encrypt", ret); return ret; } diff --git a/tests/scripts/components-configuration-crypto.sh b/tests/scripts/components-configuration-crypto.sh index d0520b5bae..d2f7c22db5 100644 --- a/tests/scripts/components-configuration-crypto.sh +++ b/tests/scripts/components-configuration-crypto.sh @@ -1766,6 +1766,8 @@ config_psa_crypto_accel_rsa () { driver_only=$1 # Start from crypto_full config (no X.509, no TLS) + # Note: PK will be ignored when comparing driver to reference in + # analyze_outcomes.py helper_libtestdriver1_adjust_config "crypto_full" if [ "$driver_only" -eq 1 ]; then
