 This also allows the issuer to "sign" a file, creating a unique signature file, which people can check against that
 file to confirm it wasn't modified. This signature can only be generated with the issuer's secret/private key, however
 anyone with the public key can check that the signature is genuine and was issued by the corresponding private key to
 their public one.

+In contrast, a symmetric encryption scheme, which is the alternative, is when the involved parties share the same key,

+they can decrypt all sent conversation easily. Symmetric encryption also lacks the possibility of meaningful signature
 generation, since to verify the signature, you'd need the single key, and if you did have that key, you could easily
 modify the file and sign in with that key, resulting in a perfectly valid signature.
