int mbedtls_sha1 | ( | const unsigned char * | input, |
size_t | ilen, | ||
unsigned char | output[20] | ||
) |
Output = SHA-1( input buffer )
input | Buffer holding the data. The input buffer needs to be big enough to hold the padding (MD-strenghtening) at the end, after the message of 'ilen' length. This function will perform MD-strengthening and append to the end of the input buffer. |
ilen | length of the input data |
output | SHA-1 checksum result |
void mbedtls_sha1_clone | ( | mbedtls_sha1_context * | dst, |
const mbedtls_sha1_context * | src | ||
) |
Clone (the state of) a SHA-1 context.
dst | The destination context |
src | The context to be cloned |
void mbedtls_sha1_finish | ( | mbedtls_sha1_context * | ctx, |
unsigned char | output[20] | ||
) |
SHA-1 final digest.
ctx | SHA-1 context |
output | SHA-1 checksum result |
void mbedtls_sha1_free | ( | mbedtls_sha1_context * | ctx | ) |
Clear SHA-1 context.
ctx | SHA-1 context to be cleared |
void mbedtls_sha1_init | ( | mbedtls_sha1_context * | ctx | ) |
Initialize SHA-1 context.
ctx | SHA-1 context to be initialized |

ctx | context to be initialized |
void mbedtls_sha1_update | ( | mbedtls_sha1_context * | ctx, |
const unsigned char * | input, | ||
size_t | ilen | ||
