Description

A JSON Web Key (JWK) is a JavaScript Object Notation (JSON) data structure that represents a cryptographic key. This module also defines a JSON Web Key Set (JWK Set) JSON data structure for representing a set of JWKs.

-- Generate RSA JWK and set "kid" param to
-- base64url-encoded SHA-256 thumbprint of key.

jwkX5c :: Getter JWK (Maybe (NonEmpty SignedCertificate)) Source #

Get the certificate chain. Not a lens, because the key of the first certificate in the chain must correspond be the public key of the JWK. To set the certificate chain use setJWKX5c.

setJWKX5c :: Maybe (NonEmpty SignedCertificate) -> JWK -> Maybe JWK Source #

Set the "x5c" Certificate Chain parameter. If setting the list, checks that the key in the first certificate matches the JWK; returns Nothing if it does not.

Converting from other key formats

fromRSA :: PrivateKey -> JWK Source #

Convert RSA private key into a JWK

fromOctets :: Cons s s Word8 Word8 => s -> JWK Source #

Convert octet string into a JWK

fromX509Certificate :: (AsError e, MonadError e m) => SignedCertificate -> m JWK Source #

Convert an X.509 certificate into a JWK.

Only RSA keys are supported. Other key types will throw KeyMismatch.

The "x5c" field of the resulting JWK contains the certificate.

JWK Thumbprint

thumbprint :: HashAlgorithm a => Getter JWK (Digest a) Source #

Compute the JWK Thumbprint of a JWK

digest :: HashAlgorithm a => Prism' ByteString (Digest a) Source #

Prism from ByteString to HashAlgorithm a => Digest a.

Use re digest to view the bytes of a digest

base64url :: (AsEmpty s1, AsEmpty s2, Cons s1 s1 Word8 Word8, Cons s2 s2 Word8 Word8) => Prism' s1 s2 Source #

Prism for encoding / decoding base64url.

To encode, review base64url. To decode, preview base64url.

Works with any combinations of strict/lazy ByteString.

Methods

getVerificationKeys :: h -> s -> JWKSet -> m [JWK] Source #

bestJWSAlg :: (MonadError e m, AsError e) => JWK -> m Alg Source #

Choose the cryptographically strongest JWS algorithm for a given key. The JWK "alg" algorithm parameter is ignored.
