Post by voffi on Converting UINT into bytes and converting 2Bytes into UINT ^{CODESYS Forge talk (Post)}
There are some ways. One is to use SHR and SHL and it depends on your byte order in the data array. For Motorola byte order: PROGRAM PLC_PRG VAR u : UINT; byte_array_in : ARRAY [1..8] OF BYTE := [16#11, 16#12, 16#13, 16#14, 16#15, 16#16, 16#17]; byte_array_out : ARRAY [1..8] OF BYTE; END_VAR u := SHL(TO_UINT(byte_array_in[2]), 8) + TO_UINT(byte_array_in[1]); byte_array_out[1] := TO_BYTE(u); byte_array_out[2] := TO_BYTE(SHR(u, 8)); If it's Intel byte order just change 1 and 2 in the array indexes.

Post by otbeka on CmpCrypto CryptoGenerateHash Not Outputting ^{CODESYS Forge talk (Post)}
Hi, I have been trying to use CryptoGenerateHash from the CmpCrypto Implementation library. My code is taken almost directly from the CryptoDemo.project example provided on Codesys Forge, yet the CryptoGenerateHash function does not write to the address listed in pHash. RTS_IEC_RESULT is OK, but I am getting nothing out of the function. No errors either, all my libraries are up to date. Any help would be appreicated! PROGRAM PLC_PRG VAR sMessage : MESSAGE := 'The red fox runs across the ice'; abyHashCode : HASH_CODE := [ 16#52, 16#ED, 16#87, 16#9E, 16#70, 16#F7, 16#1D, 16#92, 16#6E, 16#B6, 16#95, 16#70, 16#08, 16#E0, 16#3C, 16#E4, 16#CA, 16#69, 16#45, 16#D3 ]; xMessageOK : BOOL; END_VAR xMessageOK := CheckMessage(sMessage, abyHashCode); FUNCTION CheckMessage : BOOL VAR_INPUT sMessage : REFERENCE TO MESSAGE; abyHashCode : REFERENCE TO HASH_CODE; END_VAR VAR _hHASH : RTS_IEC_HANDLE := CryptoGetAlgorithmById(ui32CryptoID:=RtsCryptoID.HASH_SHA1, pResult:=0); Result : RTS_IEC_RESULT; bsMessage : RtsByteString := (ui32MaxLen:=SIZEOF(sMessage), pByData:=ADR(sMessage), ui32Len:=TO_UDINT(LEN(sMessage))); abyNewHashCode : HASH_CODE; bsNewHashCode : RtsByteString := (ui32MaxLen:=SIZEOF(abyNewHashCode), pByData:=ADR(abyNewHashCode)); diCmpResult : DINT; END_VAR Result := CryptoGenerateHash(hAlgo:=_hHASH, pData:=ADR(bsMessage), pHash:=ADR(bsNewHashCode)); diCmpResult := SysMemCmp(pBuffer1:=ADR(abyHashCode), pBuffer2:=ADR(abyNewHashCode), udiCount:=SIZEOF(HASH_CODE)); CheckMessage := diCmpResult = 0;
