Parameters

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

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.

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_CURVE_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_CURVE_SECPXXX and PSA_ECC_CURVE_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_CURVE_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}.

Macro to build an HKDF algorithm.

For example, PSA_ALG_HKDF(PSA_ALG_SHA256) is HKDF using HMAC-SHA-256.

This key derivation algorithm uses the following inputs:

• PSA_KEY_DERIVATION_INPUT_INFO is the info string used in the "expand" step. You must pass PSA_KEY_DERIVATION_INPUT_SALT before PSA_KEY_DERIVATION_INPUT_SECRET. You may pass PSA_KEY_DERIVATION_INPUT_INFO at any time after steup and before starting to generate output.

Parameters

Whether the specified algorithm is a TLS-1.2 PRF algorithm.

Parameters

alg	An algorithm identifier (value of type psa_algorithm_t).

Returns

1 if alg is a TLS-1.2 PRF algorithm, 0 otherwise. This macro may return either 0 or 1 if alg is not a supported key derivation algorithm identifier.
