is it possible to use IPFS Hash to ensure file integrity?

Question

My question is if i can use the IPFS Reference/Hash to ensure file integrity. In other words if i have a file can i use a specific Hashfunction to ensure that the generated Hash of that file is equal to the IPFS Hash of that file and therefore the file didnt change. Or do i need to generate an extra Hash for this purpose (f.e. sha256)?

thanks in advance.

From IPFS docs:

-n,          --only-hash           bool   - Only chunk and hash - do not write to disk.

So what you might want to do is:

ipfs add --only-hash <ipfs-path>
