Definition: crypto_values.h:1060

Macro to build a shortened AEAD algorithm.

A shortened AEAD algorithm is similar to the corresponding AEAD algorithm, but has an authentication tag that consists of fewer bytes. Depending on the algorithm, the tag length may affect the calculation of the ciphertext.

Parameters
aead_algAn AEAD algorithm identifier (value of type psa_algorithm_t such that PSA_ALG_IS_AEAD(alg) is true).
tag_lengthDesired length of the authentication tag in bytes.
Returns
The corresponding AEAD algorithm with the specified length.
Unspecified if alg is not a supported AEAD algorithm or if tag_length is not valid for the specified AEAD algorithm.

#define PSA_ALG_ANY_HASH   ((psa_algorithm_t)0x010000ff)

In a hash-and-sign algorithm policy, allow any hash algorithm.

This value may be used to form the algorithm usage field of a policy for a signature algorithm that is parametrized by a hash. The key may then be used to perform operations using the same signature algorithm parametrized with any supported hash.

That is, suppose that PSA_xxx_SIGNATURE is one of the following macros:

``` psa_set_key_usage_flags(&attributes, PSA_KEY_USAGE_SIGN_HASH); // or VERIFY psa_set_key_algorithm(&attributes, PSA_xxx_SIGNATURE(PSA_ALG_ANY_HASH));

  • ```

#define PSA_ALG_DETERMINISTIC_ECDSA (   hash_alg)    (PSA_ALG_DETERMINISTIC_ECDSA_BASE | ((hash_alg) & PSA_ALG_HASH_MASK))

Deterministic ECDSA signature with hashing.

This is the deterministic ECDSA signature scheme defined by RFC 6979.

The representation of a signature is the same as with PSA_ALG_ECDSA().

Note that when this algorithm is used for verification, signatures made with randomized ECDSA (PSA_ALG_ECDSA(hash_alg)) with the same private key are accepted. In other words, PSA_ALG_DETERMINISTIC_ECDSA(hash_alg) differs from PSA_ALG_ECDSA(hash_alg) only for signature, not for verification.

Parameters
hash_algA hash algorithm (PSA_ALG_XXX value such that PSA_ALG_IS_HASH(hash_alg) is true). This includes PSA_ALG_ANY_HASH when specifying the algorithm in a usage policy.
Returns
The corresponding deterministic ECDSA signature algorithm.

#define PSA_ALG_ECB_NO_PADDING   ((psa_algorithm_t)0x04404400)

The Electronic Code Book (ECB) mode of a block cipher, with no padding.

Warning
ECB mode does not protect the confidentiality of the encrypted data except in extremely narrow circumstances. It is recommended that applications only use ECB if they need to construct an operating mode that the implementation does not provide. Implementations are encouraged to provide the modes that applications need in preference to supporting direct access to ECB.

The underlying block cipher is determined by the key type.

This symmetric cipher mode can only be used with messages whose lengths are a multiple of the block size of the chosen block cipher.

ECB mode does not accept an initialization vector (IV). When using a multi-part cipher operation with this algorithm, psa_cipher_generate_iv() and psa_cipher_set_iv() must not be called.

Definition at line 999 of file crypto_values.h.

#define PSA_ALG_ECDH   ((psa_algorithm_t)0x30200000)

The elliptic curve Diffie-Hellman (ECDH) key agreement algorithm.

The shared secret produced by key agreement is the x-coordinate of the shared secret point. It is always ceiling(m / 8) bytes long where m is the bit size associated with the curve, i.e. the bit size of the order of the curve's coordinate field. When m is not a multiple of 8, the byte containing the most significant bit of the shared secret is padded with zero bits. The byte order is either little-endian or big-endian depending on the curve type.

  • For Montgomery curves (curve types PSA_ECC_FAMILY_CURVEXXX), the shared secret is the x-coordinate of d_A Q_B = d_B Q_A in little-endian byte order. The bit size is 448 for Curve448 and 255 for Curve25519.
  • For Weierstrass curves over prime fields (curve types PSA_ECC_FAMILY_SECPXXX and PSA_ECC_FAMILY_BRAINPOOL_PXXX), the shared secret is the x-coordinate of d_A Q_B = d_B Q_A in big-endian byte order. The bit size is m = ceiling(log_2(p)) for the field F_p.
  • For Weierstrass curves over binary fields (curve types PSA_ECC_FAMILY_SECTXXX), the shared secret is the x-coordinate of d_A Q_B = d_B Q_A in big-endian byte order. The bit size is m for the field F_{2^m}.

#define PSA_ALG_ECDSA (   hash_alg)    (PSA_ALG_ECDSA_BASE | ((hash_alg) & PSA_ALG_HASH_MASK))

ECDSA signature with hashing.

This is the ECDSA signature scheme defined by ANSI X9.62, with a random per-message secret number (k).

The representation of the signature as a byte string consists of the concatentation of the signature values r and s. Each of r and s is encoded as an N-octet string, where N is the length of the base point of the curve in octets. Each value is represented in big-endian order (most significant octet first).

Parameters
hash_algA hash algorithm (PSA_ALG_XXX value such that PSA_ALG_IS_HASH(hash_alg) is true). This includes PSA_ALG_ANY_HASH when specifying the algorithm in a usage policy.
Returns
The corresponding ECDSA signature algorithm.
Unspecified if hash_alg is not a supported hash algorithm.

Definition at line 1178 of file crypto_values.h.

#define PSA_ALG_ECDSA_ANY   PSA_ALG_ECDSA_BASE

ECDSA signature without hashing.

This is the same signature scheme as PSA_ALG_ECDSA(), but without specifying a hash algorithm. This algorithm may only be used to sign or verify a sequence of bytes that should be an already-calculated hash. Note that the input is padded with zeros on the left or truncated on the left as required to fit the curve size.

Get the hash used by a hash-and-sign signature algorithm.

A hash-and-sign algorithm is a signature algorithm which is composed of two phases: first a hashing phase which does not use the key and produces a hash of the input message, then a signing phase which only uses the hash and the key and not the message itself.

Parameters
algA signature algorithm (PSA_ALG_XXX value such that PSA_ALG_IS_SIGN(alg) is true).
Returns
The underlying hash algorithm if alg is a hash-and-sign algorithm.
0 if alg is a signature algorithm that does not follow the hash-and-sign structure.
Unspecified if alg is not a signature algorithm or if it is not supported by the implementation.

#define PSA_ALG_TLS12_PRF (   hash_alg)    (PSA_ALG_TLS12_PRF_BASE | ((hash_alg) & PSA_ALG_HASH_MASK))

Macro to build a TLS-1.2 PRF algorithm.

TLS 1.2 uses a custom pseudorandom function (PRF) for key schedule, specified in Section 5 of RFC 5246. It is based on HMAC and can be used with either SHA-256 or SHA-384.

This key derivation algorithm uses the following inputs, which must be passed in the order given here:

For the application to TLS-1.2 key expansion, the seed is the concatenation of ServerHello.Random + ClientHello.Random, and the label is "key expansion".

For example, PSA_ALG_TLS12_PRF(PSA_ALG_SHA256) represents the TLS 1.2 PRF using HMAC-SHA-256.

Parameters
hash_algA hash algorithm (PSA_ALG_XXX value such that PSA_ALG_IS_HASH(hash_alg) is true).
Returns
The corresponding TLS-1.2 PRF algorithm.
Unspecified if hash_alg is not a supported hash algorithm.

#define PSA_ALG_TLS12_PSK_TO_MS (   hash_alg)    (PSA_ALG_TLS12_PSK_TO_MS_BASE | ((hash_alg) & PSA_ALG_HASH_MASK))

Macro to build a TLS-1.2 PSK-to-MasterSecret algorithm.

In a pure-PSK handshake in TLS 1.2, the master secret is derived from the PreSharedKey (PSK) through the application of padding (RFC 4279, Section 2) and the TLS-1.2 PRF (RFC 5246, Section 5). The latter is based on HMAC and can be used with either SHA-256 or SHA-384.

This key derivation algorithm uses the following inputs, which must be passed in the order given here:

For the application to TLS-1.2, the seed (which is forwarded to the TLS-1.2 PRF) is the concatenation of the ClientHello.Random + ServerHello.Random, and the label is "master secret" or "extended master secret".

For example, PSA_ALG_TLS12_PSK_TO_MS(PSA_ALG_SHA256) represents the TLS-1.2 PSK to MasterSecret derivation PRF using HMAC-SHA-256.

Parameters
hash_algA hash algorithm (PSA_ALG_XXX value such that PSA_ALG_IS_HASH(hash_alg) is true).
Returns
The corresponding TLS-1.2 PSK to MS algorithm.
Unspecified if hash_alg is not a supported hash algorithm.

Definition: crypto_values.h:826

Macro to build a truncated MAC algorithm.

A truncated MAC algorithm is identical to the corresponding MAC algorithm except that the MAC value for the truncated algorithm consists of only the first mac_length bytes of the MAC value for the untruncated algorithm.

Note
This macro may allow constructing algorithm identifiers that are not valid, either because the specified length is larger than the untruncated MAC or because the specified length is smaller than permitted by the implementation.
It is implementation-defined whether a truncated MAC that is truncated to the same length as the MAC of the untruncated algorithm is considered identical to the untruncated algorithm for policy comparison purposes.
Parameters
mac_algA MAC algorithm identifier (value of type psa_algorithm_t such that PSA_ALG_IS_MAC(alg) is true). This may be a truncated or untruncated MAC algorithm.
mac_lengthDesired length of the truncated MAC in bytes. This must be at most the full length of the MAC and must be at least an implementation-specified minimum. The implementation-specified minimum shall not be zero.
Returns
The corresponding MAC algorithm with the specified length.
Unspecified if alg is not a supported MAC algorithm or if mac_length is too small or too large for the specified MAC algorithm.

Parameters
typeA cipher key type (value of type psa_key_type_t).
Returns
The block size for a block cipher, or 1 for a stream cipher. The return value is undefined if type is not a supported cipher key type.
Note
It is possible to build stream cipher algorithms on top of a block cipher, for example CTR mode (PSA_ALG_CTR). This macro only takes the key type into account, so it cannot be used to determine the size of the data that psa_cipher_update() might buffer for future processing in general.
This macro returns a compile-time constant if its argument is one.

#define PSA_KEY_TYPE_DSA_KEY_PAIR   ((psa_key_type_t)0x7002)

DSA key pair (private and public key).

The import and export format is the representation of the private key x as a big-endian byte string. The length of the byte string is the private key size in bytes (leading zeroes are not stripped).

Determinstic DSA key derivation with psa_generate_derived_key follows FIPS 186-4 §B.1.2: interpret the byte string as integer in big-endian order. Discard it if it is not in the range [0, N - 2] where N is the boundary of the private key domain (the prime p for Diffie-Hellman, the subprime q for DSA, or the order of the curve's base point for ECC). Add 1 to the resulting integer and use this as the private key x.

#define PSA_KEY_TYPE_DSA_PUBLIC_KEY   ((psa_key_type_t)0x4002)

DSA public key.

The import and export format is the representation of the public key y = g^x mod p as a big-endian byte string. The length of the byte string is the length of the base prime p in bytes.

Typedef Documentation

typedef uint32_t psa_algorithm_t

Encoding of a cryptographic algorithm.

For algorithms that can be applied to multiple key types, this type does not encode the key type. For example, for symmetric ciphers based on a block cipher, psa_algorithm_t encodes the block cipher mode and the padding mode while the block cipher itself is encoded via psa_key_type_t.

Definition at line 96 of file crypto_types.h.

typedef uint8_t psa_dh_family_t

The type of PSA Diffie-Hellman group family identifiers.

The group identifier is required to create an Diffie-Hellman key using the PSA_KEY_TYPE_DH_KEY_PAIR() or PSA_KEY_TYPE_DH_PUBLIC_KEY() macros.

Values defined by this standard will never be in the range 0x80-0xff. Vendors who define additional families must use an encoding in this range.

Definition at line 86 of file crypto_types.h.

typedef uint8_t psa_ecc_family_t

The type of PSA elliptic curve family identifiers.

The curve identifier is required to create an ECC key using the PSA_KEY_TYPE_ECC_KEY_PAIR() or PSA_KEY_TYPE_ECC_PUBLIC_KEY() macros.

Values defined by this standard will never be in the range 0x80-0xff. Vendors who define additional families must use an encoding in this range.
