Asymmetric Encryption - CI/CD Glossary Definition
Asymmetric encryption uses a mathematically linked key pair - a public key to encrypt or verify and a private key to decrypt or sign - so parties can communicate securely without sharing a secret.
Where it fits
Asymmetric algorithms like RSA and elliptic curve are slower than symmetric ones, so they are used to exchange keys and sign data rather than to bulk-encrypt.
In CI/CD
JWT and OIDC token signatures, TLS handshakes, and SSH keys all rely on asymmetric key pairs to prove identity without a shared secret.
