Cracking NSIS CRCCheck!

[Kruger]

Hi, after looking into this nice installer it only took one byte to crack the crccheck protection!!!
To bad!!!

Uhh, yeah, what's your point? The CRC check is there to help keep you from installing corrupted data.. Of course you could modify it if you really wanted to.

This guy obviously has no idea what the crc check is even for.

Hi, for starters.:
I do think i know what a crc check is...
If you make a installer someone can easy rip it/alter it etc. if the protection is not strong enough.
Maybe "PsyPab" need a new way of thinking...crc check is the only thing in this installer that gives you some sort of protection!
That's my point...

Umm, well you could use a really advanced encryption system, but then again, since NSIS is open source, anybody could see how it works and easily decrypt, right?
What's the point?

If you are that paranoid just sign the file. Better yet, provide the MD5 checksums. I don't think installshield does anymore than a crc check either.

CRC checks are designed to detect data corruption during transfers.
Digital Signatures are designed to provide security against deliberate code manipulation. Use GPG/PGP for signatures.

I don't think most of us are at all worried about someone 'cracking' our installers. After all, like Justin said NSIS is open source anyway so it wouldn't be very difficult.
