## Symmetric ciphers

- Same secret key is used for encryption/decryption
- Examples: AES, DES, 3DES, IDEA

## Asymmetric/Public Key ciphers

- Public key used for encryption and verification
- Private key used for decryption and signing
- Examples: DSA, RSA

## Hybrid ciphers

- Public Key cipher used to encrypt symmetric cipher key, which is then used to encrypt the session
