Key Pair Generator

This lesson is part of Web Developer Tools · All levels

Summary

Key pair generators create asymmetric key pairs consisting of public and private keys. Public keys may be shared for signature verification or encryption, whereas private keys must be kept confidential. Key pairs such as RSA or ECC became the basis of TLS, digital signatures, and modern authentication.

Key points

Public keys shared, private keys never shared
RSA uses a minimum key size of 2048 bits for new uses
ECC offers the same security as a shorter key
Private keys are used to sign or decrypt data
The general storage format is PEM, while DER is binary
