This is probably an engine related problem. To test this try the following on both platforms and compare [snip] Greetings, WA
PS In fact with a litle adjustment your Blowfish stack is working on both platforms
I tried it with a speed test and the solution I'm using now:
on mouseUp
## I added speed testing
put num2char("169,170,171,172") into x
## N - decode signed four-byte integers in network order
put binaryDecode("N",x,halfBlock1) into numConverted
## I - decode unsigned four-byte integers in host order
put the milliseconds into zap1
repeat with i = 1 to 100000
put binaryDecode("I",x,halfBlock2) into numConverted
end repeat
put the milliseconds into zap2
put zap2 - zap1 into t1
## my solution I'm using now
put the milliseconds into zap6
repeat with ii = 1 to 100000
put charToNum(char 4 of x) + (charToNum(char 3 of x) * 256) + (charToNum(char 2 of x) * 65536) + (charToNum(char 1 of x) * 16777216) bitAnd 4294967295 into halfBlock3
end repeat
put the milliseconds into zap7
put zap7 - zap6 into t2
put halfblock1 && halfblock2 && halfblock3 && t1 && t2
## result = -1448432724 2846534572 2846534572 294 664
end mouseUp
function num2char sx
repeat for each item i in sx
put numtochar(i) after z
end repeat
return z
end num2charI'll have to see if this works with macToIso/isoToMac for delivery. I'm curently using ascii numbers that in the end take the charSet issue out of the delivery issue for decryption. The numbers also split out into an array that allows for one step to be dropped during decryption.
Thank you for mentioning this. This could add at the least a 100% increase in speed to the current state of the working version.
