**Asymmetric Cryptography** | **Asymmetric Password** 1. Asymmetric [[Cryptography|cryptography]] is also known as [[Public Key|public key]] cryptography. It uses public and [[Private Key|private keys]] to encrypt and decrypt data. The keys are large numbers that have been paired together but are not identical (asymmetric). A public key can be shared with everyone. The [[Private Key|private key]] in the pair is kept secret. [[Protocol(s)]] such as SSH, S/MIME rely on asymmetric [[Cryptography|cryptography]] for encryption and digital [[Signature|signature]] functions. 3. Asymmetric encryption is a [[Cryptography|cryptographic]] system that uses a [[Public Key]] for encryption and a [[Private Key]] for decryption. The public key can be shared with anyone, while the private key is meant to be kept secret to maintain security. Asymmetric encryption is considered more secure than [[symmetric encryption]], which uses one key for both encryption and decryption. The [[Bitcoin (blockchain)]] network uses asymmetric encryption.
