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}.

Note that the input is padded with zeros on the left or truncated on the left as required to fit the curve size.

Whether the specified algorithm is a stream cipher.

A stream cipher is a symmetric cipher that encrypts or decrypts messages by applying a bitwise-xor with a stream of bytes that is generated from a key.

Parameters

alg	An algorithm identifier (value of type psa_algorithm_t).

Returns

1 if alg is a stream cipher algorithm, 0 otherwise. This macro may return either 0 or 1 if alg is not a supported algorithm identifier or if it is not a symmetric cipher algorithm.

Whether the specified algorithm is a stream cipher.

A stream cipher is a symmetric cipher that encrypts or decrypts messages by applying a bitwise-xor with a stream of bytes that is generated from a key.

Parameters

alg	An algorithm identifier (value of type psa_algorithm_t).

Returns

1 if alg is a stream cipher algorithm, 0 otherwise. This macro may return either 0 or 1 if alg is not a supported algorithm identifier or if it is not a symmetric cipher algorithm.

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.
