Digital signature
In Turkish: Dijital imza
A way to prove that a message or file really came from a given sender and was not changed on the way.
A sender uses a private key to sign, and anyone can check the signature with the matching public key. It is how software updates, secure websites and many documents are verified as genuine.
A digital signature is not the same as an image of a handwritten signature pasted on a file; a picture of a signature proves nothing. The legal weight of electronic signatures depends on the kind of signature and the rules that apply, so ask the relevant institution if it matters.
What to do
- Download software only from the maker's official site or app store.
- Be careful with a document that only shows a pasted signature image.
- Ask the institution which kind of signature is accepted for your case.
