Hello,
I am debugging a problem with SHA1 checksums. I have found the following ha=
ndy one-liner on Stack Overflow [^1], which serves well as a minimal exampl=
e:
```
perl -MDigest::SHA1=3Dsha1_hex -le "print sha1_hex <>" secure.txt
```
The problem is, that the result is simply not correct. Doing the same on a =
Unix system gives the correct result. And I also get a correct result when =
I generate the SHA1 sum with the 7-zip file manager.
Any ideas what the problem might be?
