Symmetric Encryption vs. Asymmetric Encryption? How it Works …

WebFeb 13, 2024 · Typically, the asymmetric key system uses a public key for encryption and a private key for decryption. However, when dealing with digital signatures, it’s the opposite. The private key is used to encrypt the signature, and the public key is used to decrypt it. WebNov 15, 2015 · @headcode it only applies to asymmetric keys. Symmetric keys don't come in pairs. – slim Jul 4, 2015 at 18:06 3 In fact, it only applies to RSA keys. With ECDSA keys, for example, you can trivially generate the public key from the private key, and the private key is a scalar while the public key is a coordinate. – David Schwartz
