Verify k-lite codec windows 10 file SHA256

I'm trying to verify the hashes with kleopatra(or anything really)

I assume you have windows as the file is an exe. Try using Powershell to get the file's hash

Get-FileHash C:\path\to\your_file -Algorithm SHA256 | select hash

where C:\path\to\your_file is the path to your file.

This is the output after downloading and checking the hash:

PS C:\Downloads\Programs> Get-FileHash "kl*" -Algorithm SHA256 | select hash

Hash
----
C62ADDBEA3CC244020B7B587838F9E65A2F8B4FE31252C1B34B0F8EEAF6D7FC6

which is the hash listed on the linked page.

SHA256 hash of the file as shown on the linked page
