Detailed Description

SHA-2 (Secure Hash Algorithm 2)

SHA-384 and SHA-512 are secure hash functions belonging to the SHA-2 family with a digest length of 384 and 512 bits, respectively. The message length should be less than 2¹²⁸ bits. Refer to FIPS 180-4 for more details.

Macro Definition Documentation

CX_SHA384_SIZE

#define CX_SHA384_SIZE   48

SHA-384 message digest size.

CX_SHA512_SIZE

#define CX_SHA512_SIZE   64

SHA-512 message digest size.

Typedef Documentation

cx_sha512_t

See cx_sha512_s.

Function Documentation

cx_hash_sha512()

size_t cx_hash_sha512	(	const uint8_t *	in,
		size_t	in_len,
		uint8_t *	out,
		size_t	out_len
)

Computes a one shot SHA-512 digest.

Parameters

[in]	in	Input data.
[in]	in_len	Length of the input data.
[out]	out	Buffer where to store the output.
[out]	out_len	Length of the output. This is actually 512 bits.

cx_sha384_init()

static int cx_sha384_init ( cx_sha512_t *  hash )

Initializes a SHA-384 context.

Parameters

hash

Pointer to the context. The context shall be in RAM.

Returns

SHA384 identifier.

cx_sha384_init_no_throw()

cx_err_t cx_sha384_init_no_throw

(

cx_sha512_t *

hash

)

Initializes a SHA-384 context.

Parameters

[out]

hash

Pointer to the context. The context shall be in RAM.

Returns

Error code:

• CX_OK on success

cx_sha512_init()

static int cx_sha512_init ( cx_sha512_t *  hash )

Initializes a SHA-512 context.

Parameters

Returns

SHA512 identifier.

cx_sha512_init_no_throw()

cx_err_t cx_sha512_init_no_throw

(

cx_sha512_t *

hash

)

Initializes a SHA-512 context.

Parameters

[out]

hash

Pointer to the context. The context shall be in RAM.

Returns

Error code:

• CX_OK on success
