This file contains SHA-384 and SHA-512 definitions and functions.
The Secure Hash Algorithms 384 and 512 (SHA-384 and SHA-512) cryptographic hash functions are defined in FIPS 180-4: Secure Hash Standard (SHS).

#define MBEDTLS_ERR_SHA512_BAD_INPUT_DATA -0x0075 |
#define MBEDTLS_ERR_SHA512_HW_ACCEL_FAILED -0x0039 |
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().
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.
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. |

size_t | ilen, | ||
unsigned char | output[64], | ||
int | is384 | ||
) |
This function calculates the SHA-512 or SHA-384 checksum of a buffer.
The function allocates the context, performs the calculation, and frees the context.

ilen | The length of the input data in Bytes. |
output | The SHA-384 or SHA-512 checksum result. This must be a writable buffer of length 64 Bytes. |
is384 | Determines which function to use. This must be either 0 for SHA-512, or 1 for SHA-384. |
