#include "xf_security/sha1.hpp"
template <unsigned int w> void sha1 ( hls::stream <ap_uint <w>>& msg_strm, hls::stream <ap_uint <64>>& len_strm, hls::stream <bool>& end_len_strm, hls::stream <ap_uint <5*w>>& digest_strm, hls::stream <bool>& end_digest_strm )
Top function of SHA-1.
The algorithm reference is : “Secure Hash Standard”, which published by NIST in February 2012. The implementation dataflows the pre-processing part and message digest part.
Parameters:
| w | The bit width of each input message word, default value is 32. |
| msg_strm | The message being hashed. |
| len_strm | The message length in byte. |
| end_len_strm | The flag to signal end of input message stream. |
| digest_strm | Output digest stream. |
| end_digest_strm | End flag for output digest stream. |
