Programm to create hashes list and verify it.

[RJ_STN]

Hi!

Please, help me to find a free portable programm (or not portable but without installation) software to calculate hashes for files in directory and save it in txt files, something like:
1.txt fsdfsdfsdfasdfasd (hash, md5 or sha256)
2. txt dfsd2232j.dfsjdf
... and so on.
Files are big (1-2 Gb) and total their size about 4 Tb.
And then, one can use that hashes file to verify files and show files:
a) exists in directory, but not in hash file
b) exists in hash file, but not exists in directory
c) hash correct
d) hash incorrect (file changed).

OpenSFV programm can something like that, but it need installation and on my PC installator closes with error.

RapidCRC Unicode?

For sure also something else, just check in Checksum Calculators and Integrity Checkers categories

RapidCRC Unicode?

I agree with billon: I like RapidCRC Unicode (fast, works with huge files and huge file lists, dev is responsive) but I should point out that - when checking hashes - it ignores anything not part of the hash:

So for example, I created a list of 3 files (Temp.7z, file1.txt, file2.txt) and generated a hash file. I then changed file2.txt and added file3.txt. As you can see below, it ignored file3.txt:



You might submit a github issue and ask him to add that functionality.
