Ed448
EdDSA signatures over Curve448 (RFC 8032) — the higher-security-margin sibling of Ed25519, using SHAKE256 internally instead of SHA-512. Completes the Curve25519/Curve448 x agreement/signing grid alongside x25519, x448, and ed25519.

An asymmetric cipher based on the difficulty of factoring large semiprimes. Supports key generation, encryption, and decryption.
The finite-field discrete-log ancestor of ECDSA (NIST FIPS 186, 1994) — same r/s signature equation, computed in a prime-order subgroup instead of on a curve. Demo uses toy parameters; real DSA needs p>=2048 bits, q>=224 bits.
A key exchange protocol enabling two parties to establish a shared secret over an insecure channel.
