DSA
DSA
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.

Imported traces are validated and replayed locally. They never run a cipher operation automatically.

An asymmetric cipher based on the difficulty of factoring large semiprimes. Supports key generation, encryption, and decryption.
A key exchange protocol enabling two parties to establish a shared secret over an insecure channel.
Diffie-Hellman key exchange over Curve448 (RFC 7748) — the higher-security sibling of X25519, targeting ~224-bit security with 56-byte keys instead of X25519's 32-byte keys.
