void NutMD5Init | ( | MD5CONTEXT * | context | ) |
Start MD5 accumulation.
Start MD5 accumulation, set bit count to 0 and buffer to mysterious initialization constants. Call this function to initialize every new MD5 calculation.
context | Points to the md5 context buffer. |

uint8_t CONST * | buf, | |||
uint32_t | len | |||
) |
Update MD5 context.
Update context to reflect the concatenation of another data buffer.
context | Points to the md5 context buffer. | |
buf | Points to the data buffer | |
len | Length of the data buffer |

uint8_t | digest[16] | |||
) |
Final wrapup, calculate MD5 digest.
Final wrapup - pad to 64-byte boundary with the bit pattern 1 0* (64-bit count of bits processed, MSB-first) Fill in the digest into digest buffer
context | Points to the md5 context buffer. | |
digest | Points to the digest buffer, which must be 16 bytes long |
