| typedef struct mbedtls_sha1_context mbedtls_sha1_context |
The SHA-1 context structure.
| int mbedtls_internal_sha1_process | ( | mbedtls_sha1_context * | ctx, |
| const unsigned char | data[64] | ||
| ) |
SHA-1 process data block (internal use only).
| ctx | The SHA-1 context to use. This must be initialized. |
| data | The data block being processed. This must be a readable buffer of length 64 Bytes. |
0 on success. | MBEDTLS_DEPRECATED void mbedtls_sha1 | ( | const unsigned char * | input, |
| size_t | ilen, | ||
| unsigned char | output[20] | ||
| ) |
This function calculates the SHA-1 checksum of a buffer.
The function allocates the context, performs the
calculation, and frees the context.
The SHA-1 result is calculated as
output = SHA-1(input buffer).
| input | The buffer holding the input data. This must be a readable buffer of length ilen Bytes. |
| ilen | The length of the input data input in Bytes. |
| output | The SHA-1 checksum result. This must be a writable buffer of size 20 Bytes. |
| void mbedtls_sha1_clone | ( | mbedtls_sha1_context * | dst, |
| const mbedtls_sha1_context * | src | ||
| ) |
This function clones the state of a SHA-1 context.
| dst | The SHA-1 context to clone to. This must be initialized. |
| src | The SHA-1 context to clone from. This must be initialized. |
| MBEDTLS_DEPRECATED void mbedtls_sha1_finish | ( | mbedtls_sha1_context * | ctx, |
| unsigned char | output[20] | ||
| ) |
This function finishes the SHA-1 operation, and writes the result to the output buffer.
| ctx | The SHA-1 context. This must be initialized and have a hash operation started. |
| output | The SHA-1 checksum result. This must be a writable buffer of length 20 Bytes. |
| int mbedtls_sha1_finish_ret | ( | mbedtls_sha1_context * | ctx, |
| unsigned char | output[20] | ||
| ) |
This function finishes the SHA-1 operation, and writes the result to the output buffer.
| ctx | The SHA-1 context to use. This must be initialized and have a hash operation started. |
| output | The SHA-1 checksum result. This must be a writable buffer of length 20 Bytes. |
0 on success. | void mbedtls_sha1_free | ( | mbedtls_sha1_context * | ctx | ) |
This function clears a SHA-1 context.
| ctx | The SHA-1 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-1 context. |
| void mbedtls_sha1_init | ( | mbedtls_sha1_context * | ctx | ) |
This function initializes a SHA-1 context.
| ctx | The SHA-1 context to initialize. This must not be NULL. |
