Compute MD5 message digest for 'len' bytes beginning at 'buffer'. The result is always in little endian byte order, so that a byte-wise output yields to the wanted ASCII representation of the message digest.

int BLI_hash_md5_stream | ( | FILE * | stream, |

Compute MD5 message digest for bytes read from 'stream'. The resulting message digest number will be written into the 16 bytes beginning at 'resblock'.

Starting with the result of former calls of this function (or the initialization), this function updates the 'ctx' context for the next 'len' bytes starting at 'buffer'. It is necessary that 'len' is a multiple of 64!!!

Put result from 'ctx' in first 16 bytes of 'resbuf'. The result is always in little endian byte order, so that a byte-wise output yields to the wanted ASCII representation of the message digest.
