I think, the help is not correct. The ciphering using always 16 Bytes.

Code: Select all
destLen = compressBound(sourceLen) ; destLen = sourceLen + 13 + (Int(sourceLen / 100))
FileHeader\crc = crc32(#Null, *mem, size) ; CRC32Fingerprint(*mem, size)
Thanks for the hint, i have changed to compressBound, crc is unchanged, this make no difference.

I tried to update the code to PB 5.4 Beta but I'm getting crc error when reading *.ico files but ok with png in zbin file. Any idea?
Code: Select all
UseMD5Fingerprint()
;If MD5Fingerprint(*keybuffer, #zBin_HASH_Size) <> PeekS(@\Header\HASH[0], -1, #PB_Ascii)
If Fingerprint(*keybuffer, #zBin_HASH_Size, #PB_Cipher_MD5) <> PeekS(@\Header\HASH[0], -1, #PB_Ascii)
Code: Select all
UseCRC32Fingerprint()
;If CRC32Fingerprint(*dest, MemorySize(*dest)) = \FileInfo(Number - 1)\crc
If Val("$" + Fingerprint(*dest, MemorySize(*dest), #PB_Cipher_CRC32)) = \FileInfo(Number - 1)\crc

Add at the end of "zBin_Common.pbi"
Code: Select all
CompilerIf #PB_Compiler_Version >= 540
UseMD5Fingerprint()
Procedure.s MD5Fingerprint(*hashbuffer, Size)
ProcedureReturn Fingerprint(*hashbuffer, Size, #PB_Cipher_MD5)
EndProcedure
UseCRC32Fingerprint()
Procedure CRC32Fingerprint(*mem, size)
ProcedureReturn Val("$" + Fingerprint(*mem, size, #PB_Cipher_CRC32))
EndProcedure
CompilerEndIf
I hope, this works.
Greetings Thomas

Hi Thomas, its still crc error. It only happens when reading *.ico files in zbin. I'm testing the gui unpacker code.
\FileInfo(Number-1)\crc
negative value when reading *.ico in
zBinUnpack_CatchFile. Reading png is ok.

It's an unsigned long comparing with integer probem.
NicTheQuick pointed me to this at
http://www.purebasic.fr/german/viewtopi ... 75#p332175 
.
Just replace each
\FileInfo(Number-1)\crc
in the zBin_Unpack.pbi with
Code: Select all
\FileInfo(Number-1)\crc & $ffffffff
This do the trick, quick and dirty
