Typedef Documentation

◆ mbedtls_sha512_context

typedef struct mbedtls_sha512_context mbedtls_sha512_context

The SHA-512 context structure.

            The structure is used both for SHA-384 and for SHA-512
            checksum calculations. The choice between these two is
            made in the call to mbedtls_sha512_starts_ret().

Function Documentation

◆ mbedtls_sha512_init()

void mbedtls_sha512_init ( mbedtls_sha512_context * ctx )

This function initializes a SHA-512 context.

Parameters

ctx	The SHA-512 context to initialize. This must not be `NULL`.

◆ mbedtls_sha512_free()

void mbedtls_sha512_free ( mbedtls_sha512_context * ctx )

This function clears a SHA-512 context.

Parameters

ctx	The SHA-512 context to clear. This may be `NULL`, in which case this function does nothing. If it is not `NULL`, it must point to an initialized SHA-512 context.

◆ mbedtls_sha512_clone()

void mbedtls_sha512_clone	(	mbedtls_sha512_context *	dst,
		const mbedtls_sha512_context *	src

This function clones the state of a SHA-512 context.

Parameters

dst	The destination context. This must be initialized.
src	The context to clone. This must be initialized.

◆ mbedtls_sha512_starts_ret()

int mbedtls_sha512_starts_ret	(	mbedtls_sha512_context *	ctx,

This function starts a SHA-384 or SHA-512 checksum calculation.

Parameters

ctx	The SHA-512 context to use. This must be initialized.
is384	Determines which function to use. This must be either `0` for SHA-512, or `1` for SHA-384.

Note: When MBEDTLS_SHA512_NO_SHA384 is defined, is384 must be 0, or the function will return MBEDTLS_ERR_SHA512_BAD_INPUT_DATA.

Returns: 0 on success.; A negative error code on failure.

◆ mbedtls_sha512_update_ret()

int mbedtls_sha512_update_ret	(	mbedtls_sha512_context *	ctx,
		const unsigned char *	input,
		size_t	ilen
	)

This function feeds an input buffer into an ongoing SHA-512 checksum calculation.

Parameters

ctx	The SHA-512 context. This must be initialized and have a hash operation started.
input	The buffer holding the input data. This must be a readable buffer of length `ilen` Bytes.
ilen	The length of the input data in Bytes.

Returns: 0 on success.; A negative error code on failure.

◆ mbedtls_sha512_finish_ret()

int mbedtls_sha512_finish_ret	(	mbedtls_sha512_context *	ctx,
		unsigned char	output[64]
	)

This function finishes the SHA-512 operation, and writes the result to the output buffer.

Parameters

ctx	The SHA-512 context. This must be initialized and have a hash operation started.
output	The SHA-384 or SHA-512 checksum result. This must be a writable buffer of length `64` Bytes.

Returns: 0 on success.; A negative error code on failure.

◆ mbedtls_internal_sha512_process()

int mbedtls_internal_sha512_process	(	mbedtls_sha512_context *	ctx,
		const unsigned char	data[128]
	)

This function processes a single data block within the ongoing SHA-512 computation.

This function is for internal use only.

Parameters

ctx	The SHA-512 context. This must be initialized.
data	The buffer holding one block of data. This must be a readable buffer of length `128` Bytes.

Returns: 0 on success.; A negative error code on failure.

◆ mbedtls_sha512_starts()

void mbedtls_sha512_starts	(	mbedtls_sha512_context *	ctx,
		int	is384
	)

This function starts a SHA-384 or SHA-512 checksum calculation.

Deprecated:: Superseded by mbedtls_sha512_starts_ret() in 2.7.0

Parameters

ctx	The SHA-512 context to use. This must be initialized.
is384	Determines which function to use. This must be either `0` for SHA-512 or `1` for SHA-384.
