- The advantage of Asymmetric encryption is that it does not force the user to share (secret) keys as symmetric encryption does, therefore removing the necessity of key distribution and 3-rd party/communication channel risk. Asymmetric encryption supports digital signing (via Digital Certificates) which authenticates the recipient identity and make sure that message is not tampered in transit.
- The cons of Asymmetric encryption are that it is time-intensive and it requires considerably more effort. Furthermore, you can send encrypted message only if the other person has created key pairs which means the other person must be knowledgeable. Finally, if you lose your private key – you will lose it forever. The private key is irrecoverable which could create a whole series of new problems to deal with.
