ChaCha20-Poly1305

RFC 8439 AEAD combining the existing ChaCha20 and Poly1305 modules — the software-oriented alternative to AES-GCM, used by TLS 1.3 and WireGuard when hardware AES acceleration isn't available.

XChaCha20
Secure

The 192-bit-nonce extension of ChaCha20 (used by libsodium) — an HChaCha20 subkey-derivation step, the ChaCha20 sibling of this batch's XSalsa20, lets you pick nonces randomly instead of managing a counter.

ASCON-128
Secure

NIST-selected lightweight cryptography standard (SP 800-232, 2023). Authenticated encryption with associated data (AEAD) — encrypts and authenticates simultaneously using a 320-bit sponge permutation. Designed for IoT and constrained devices. Output = nonce + ciphertext + 128-bit tag.

HMAC-SHA256
Secure

Keyed-hash Message Authentication Code. Combines SHA-256 with a cryptographic secret key.
