DOWNLOAD $($from OneDrive$)$: file$-3-$signature.zipLinks to an external site.

Once unzipped, there should be two files in the folder:

$1)$ file$-3.$txt

$2)$ file$-3.$txt$.$asc

The file$-3.$txt has been signed by me using my private key.

The file$-3.$txt$.$asc is a "detached" signature file. It contains the signature for the file$-3.$txt$.$

Download My Public Key Certificate from One Drive if needed: You should already have my public key certificate as you used it in the Cryptography assignment. However, here it is again just in case: Shaji$-$Khan$-$TEST$-$OpenPGP$-$Public$-$Certificate.ascLinks to an external site.

Verify whether the signature is valid given the public key above.
