Algorithms — every signature algorithm mkit speaks. Wire numbers are load-bearing. Do NOT renumber. New algorithms append.

Variants

ALGORITHM_UNSPECIFIED = 0

ALGORITHM_ED25519 = 1

Ed25519 over raw signing payload. The default for mkit commit/ref signing.

ALGORITHM_SECP256K1 = 2

ECDSA over secp256k1 with SHA-256 (Bitcoin-flavoured curve, NOT secp256r1). DSSE compatible.

ALGORITHM_P256 = 3

ECDSA over P-256 with SHA-256 (NIST-flavoured curve, also called secp256r1 / prime256v1). DSSE compatible.

ALGORITHM_ED25519_WEBAUTHN = 4

Ed25519, but the signing input is wrapped in a WebAuthn ClientDataJSON + authenticatorData per CTAP2. Used by the FIDO2/WebAuthn signer.

ALGORITHM_BLS12381_THRESHOLD = 5

BLS12-381 threshold signature. The wire signature is the aggregated form recovered from M-of-N partial signatures (variant MinSig — public key in G1, signature in G2, 96 bytes compressed). The DSSE keyid carries the aggregated group public key, NOT a per-share public key — every signer in the M-of-N cohort emits a partial signature that combines into a single signature verifiable against one keyid.

Defined in docs/specs/SPEC-RELEASE-THRESHOLD.md. Used by the “release party” flow where N maintainers co-sign a release without each maintainer’s signature appearing on the wire.
