RC4 unicode support?

[tmplinshi]

I'm using https://github.com/ahkscript/libcrypt.a ... rc/RC4.ahk for RC4 Encryption/Decryption, but it doesn't support unicode characters.

The folowing code displays Paste your 数据 here, but the correct result should be Paste your 数据 here as shown in this online RC4 tool.

Code: Select all

MsgBox % LC_RC4_Decrypt("CC0F1F0B6A005AA797149C55F4B2038A02496968A13A", "SECRET")

; https://github.com/ahkscript/libcrypt.ahk/blob/master/src/RC4.ahk
LC_RC4_Encrypt(Data,Pass) {
	Format:=A_FormatInteger,b:=0,j:=0,Key:=Object(),sBox:=Object()
	SetFormat,Integer,Hex
	VarSetCapacity(Result,StrLen(Data)*2)
	Loop 256
		a:=(A_Index-1),Key[a]:=Asc(SubStr(Pass,Mod(a,StrLen(Pass))+1,1)),sBox[a]:=a
	Loop 256
		a:=(A_Index-1),b:=(b+sBox[a]+Key[a])&255,sBox[a]:=(sBox[b]+0,sBox[b]:=sBox[a]) ; SWAP(a,b)

		,Result.=SubStr(Asc(A_LoopField)^sBox[k],-1,2)
	StringReplace,Result,Result,x,0,All
	SetFormat,Integer,%Format%
	Return Result
}

LC_RC4_Decrypt(Data,Pass) {
	b:=0,j:=0,x:="0x",Key:=Object(),sBox:=Object()
	VarSetCapacity(Result,StrLen(Data)//2)
	Loop 256
		a:=(A_Index-1),Key[a]:=Asc(SubStr(Pass,Mod(a,StrLen(Pass))+1,1)),sBox[a]:=a
	Loop 256
		a:=(A_Index-1),b:=(b+sBox[a]+Key[a])&255,sBox[a]:=(sBox[b]+0,sBox[b]:=sBox[a]) ; SWAP(a,b)

		,Result.=Chr((x . SubStr(Data,(2*A_Index)-1,2))^sBox[k])
	Return Result
}

Can anyone help please?
