Beginner Topic 15 of 51 Security & Cryptography
Asymmetric Encryption
Encryption with paired public and private keys.
How it works
A key pair: the public key encrypts or verifies, the private key decrypts or signs. It solves key distribution but is slow, so it protects symmetric keys.
Where it is used
TLS handshakes, PGP, SSH.
Common pitfall
Private key leakage breaks everything; protect and rotate keys.
Where it fits in the course
Asymmetric Encryption is topic 15 of 51 in Security & Cryptography, rated Beginner. It follows AES. The next topic is RSA.
