 The encryption is based on a given passphrase, which can be choosen by the user. However, a default-passphrase "cardano" should be used to encrypt/decrypt if no other passphrase is provided or known.
   
+OpenSSL uses [PKCS#7](https://datatracker.ietf.org/doc/html/rfc5652#section-6.3) as padding. The adopted cipher accepts only multiple of 16-byte blocks. Not fitting messages to be encrypted are filled with the number of padding bytes that are needed to form multiple of 16-bytes. So if 1 byte of padding is required, the padding "01" is added. If 2 bytes of padding are needed, "02 02" is added. If no padding is required, an extra block of 0x10 bytes is added, meaning sixteen "10" bytes. In order to be interoperable with OpenSSL this kind of padding is a requirement.

 ##### Why a default passphrase?
   
 As pointed out above, its way harder for man-in-the-middle listeners, to decrypt every single message on the fly. So by using a default passphrase, tools can encrypt messages and explorers/wallets can autodecrypt such messages trying to use the default passphrase. In that way, the displayed message is automatically readable to the user. If a more protected communication is needed, the sender can choose a custom passphrase and communicate that to the receiver as a preshared passphrase.
