ECIES (X25519)
ECIES (X25519)
Hybrid encryption: ephemeral X25519 key agreement + HKDF + AEAD, letting a sender encrypt an arbitrary-length message directly to a recipient's public key — no other asymmetric module here does this end-to-end.

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.
