| 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().
| 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.
| 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. |
0 on success. | MBEDTLS_DEPRECATED void mbedtls_sha512 | ( | const unsigned char * | input, |
| 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.
The SHA-512 result is calculated as output = SHA-512(input buffer).
| input | The buffer holding the data. This must be a readable buffer of length ilen Bytes. |
| 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. |
| void mbedtls_sha512_clone | ( | mbedtls_sha512_context * | dst, |
| const mbedtls_sha512_context * | src | ||
| ) |
This function clones the state of a SHA-512 context.
| dst | The destination context. This must be initialized. |
| src | The context to clone. This must be initialized. |
| MBEDTLS_DEPRECATED void mbedtls_sha512_finish | ( | mbedtls_sha512_context * | ctx, |
| unsigned char | output[64] | ||
| ) |
This function finishes the SHA-512 operation, and writes the result to the output buffer.
| 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 size 64 Bytes. |
