Public key material corresponding to a private XMLDSig signing key.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Rsa

RSA public key with DER SubjectPublicKeyInfo and normalized parameters.

Fields

spki_der: Vec<u8>

DER-encoded SubjectPublicKeyInfo bytes.

modulus: Vec<u8>

Unsigned big-endian RSA modulus (n), normalized without leading zeroes.

exponent: Vec<u8>

Unsigned big-endian RSA public exponent (e), normalized without leading zeroes.

Ec

EC public key with DER SubjectPublicKeyInfo and XMLDSig 1.1 KeyValue data.

Fields

spki_der: Vec<u8>

DER-encoded SubjectPublicKeyInfo bytes.

curve_oid: &'static str

Bare named-curve OID, without the XMLDSig urn:oid: prefix.

public_key: Vec<u8>

Uncompressed SEC1 point (0x04 || x || y).

Dsa

DSA public key and signature component width.

Fields

spki_der: Vec<u8>

DER-encoded SubjectPublicKeyInfo bytes.

p: Vec<u8>

Prime modulus P, normalized as unsigned big-endian bytes.

q: Vec<u8>

Prime divisor Q, normalized as unsigned big-endian bytes.

g: Vec<u8>

Generator G, normalized as unsigned big-endian bytes.

y: Vec<u8>

Public value Y, normalized as unsigned big-endian bytes.

modulus_bits: usize

Prime modulus width used for signing policy.

component_len: usize

Fixed XMLDSig width of each r and s component.

Hmac

Symmetric HMAC key metadata without exposing secret bytes.

Fields

key_bits: usize

Secret length used for signing policy.

EdDsa

EdDSA key metadata; the algorithm fixes its wire format and width.

Fields

algorithm: SignatureAlgorithm

Pure EdDSA method supported by this key.

spki_der: Vec<u8>

DER SubjectPublicKeyInfo with absent RFC 8410 parameters.

PostQuantum

Experimental PQ key metadata; permission is independent of this capability.

Fields

algorithm: PqAlgorithm

Exact FIPS parameter set.

spki_der: Vec<u8>

DER SubjectPublicKeyInfo with absent parameters.
