SHA3Lib

SHA3Lib provides a SHA-3 digest generation FB for Sysmac Studio. OMRON's Sysmac Studio is required to view and execute the code.

Environment

Sysmac Studio Version 1.60

How to use "SHA3Lib.slr"

1. git clone this repository or download the zip.
2. Reference "SHA3Lib.slr" in your project.

Also check "SHA3LibExample.smc2".

How to use "SHA3LibExample.smc2"

1. git clone this repository or download the zip.
2. Open "SHA3LibExample.smc2" in Sysmac Studio.
3. Check "POU/Program/README".
4. Build the project.
5. Execute on simulator or actual machine.

"SHA3LibExample.smc2" includes "SHA3Lib.slr".

Explanation

SHA3Lib provides SHA-3 digest generation FB. FB generates a digest from an input sequence of bytes.

CASE iState OF
    0:
        iMessage := 'abc'; // 3a985da74fe225b2045c172d6bd390bd855f086e3e9d525b46bfe24511431532
        iBinMessageSize := StringToAry(In:=iMessage,
                                       AryOut:=iBinMessage[0]);
        iBinMessageHead := 0;
        iSHA3_256StreamDigest(Execute:=FALSE,
                              Stream:=iBinMessage,
                              StreamHead:=iBinMessageHead);
		
        Inc(iState);
    1:
        WHILE NOT iSHA3_256StreamDigest.Done DO
            iSHA3_256StreamDigest(Execute:=TRUE,
                                  Stream:=iBinMessage,
                                  StreamHead:=iBinMessageHead,
                                  StreamSize:=iBinMessageSize,
                                  HashStr=>iHashStr);
        END_WHILE;
		
        Inc(iState);
END_CASE;

File hash

I recommend checking the hash value of the acquired Sysmac Studio project.
