Variable SignatureSchemeConst

Supported digital signature schemes.

This enum represents the various signature schemes supported in this package.

• Schnorr: BIP-340 Schnorr signature scheme (secp256k1) - DEFAULT
• ECDSA: ECDSA signature scheme (secp256k1)
• Ed25519: RFC 8032 signatures
• MLDSA44: ML-DSA44 post-quantum signature scheme (NIST level 2)
• MLDSA65: ML-DSA65 post-quantum signature scheme (NIST level 3)
• MLDSA87: ML-DSA87 post-quantum signature scheme (NIST level 5)
• SshEd25519: Ed25519 via SSH agent
• SshDsa: DSA via SSH agent
• SshEcdsaP256: ECDSA P-256 via SSH agent
• SshEcdsaP384: ECDSA P-384 via SSH agent

Wire format note: the reference models SignatureScheme as a unit-only enum; TypeScript uses string-typed values for ergonomic switch/equals checks. The CBOR/UR wire format never includes the scheme name — only the scheme's integer/byte-string discriminator on Signature, SigningPrivateKey, SigningPublicKey — so this is a stylistic difference, not a parity gap.
