Generates a new JOSE.JWK
based on another JOSE.JWK
or from initialization params provided.
Passing another JOSE.JWK
results in different behavior depending on the "kty"
:
"EC"
- uses the same named curve to generate a new key"oct"
- uses the byte size to generate a new key"OKP"
- uses the same named curve to generate a new key"RSA"
- uses the same modulus and exponent sizes to generate a new key
The following initialization params may also be used:
{:ec, "P-256" | "P-384" | "P-521"}
- generates an"EC"
key using the"P-256"
,"P-384"
, or"P-521"
curves{:oct, bytes}
- generates an"oct"
key made of a randombytes
number of bytes{:okp, :Ed25519 | :Ed25519ph | :Ed448 | :Ed448ph | :X25519 | :X448}
- generates an"OKP"
key using the specified EdDSA or ECDH edwards curve{:rsa, modulus_size} | {:rsa, modulus_size, exponent_size}
- generates an"RSA"
key using themodulus_size
andexponent_size
