Jwk class

A JWK (RFC 7517: "JSON Web Key") formatted cryptographic key.

Examples of JSON representation

AES 128 bit key

final key = Jwt.fromJson({
  "kty": "OCT",
  "alg":"A128KW",
  "k": "{BYTES_IN_BASE64URI}",
});

Ed25519 private key

final key = Jwt.fromJson({
  "kty": "OKP",
  "crv": "Ed25519",
  "d": "{BYTES_IN_BASE64URI}",
  "x": "{BYTES_IN_BASE64URI}",
});

P-256 private key

final key = Jwt.fromJson({
  "kty": "EC",
  "crv": "P-256",
  "d": "{BYTES_IN_BASE64URI}",
  "x": "{BYTES_IN_BASE64URI}",
  "y": "{BYTES_IN_BASE64URI}",
});

RSA private key

final key = Jwt.fromJson({
  "kty": "RSA",
  "n": "{BYTES_IN_BASE64URI}",
  "e": "{BYTES_IN_BASE64URI}",
  "d": "{BYTES_IN_BASE64URI}",
  "q": "{BYTES_IN_BASE64URI}",
  "dp": "{BYTES_IN_BASE64URI}",
  "dq": "{BYTES_IN_BASE64URI}",
  "qi": "{BYTES_IN_BASE64URI}",
})
