Examples

Create a 256bit symmetric key::

>>> from jwcrypto import jwk
>>> key = jwk.JWK.generate(kty='oct', size=256)

Export the key with::

>>> key.export()    
'{"k":"...","kty":"oct"}'

Create a 2048bit RSA key pair::

>>> jwk.JWK.generate(kty='RSA', size=2048) 
{"kid":"Missing Key ID","thumbprint":"..."}

Create a P-256 EC key pair and export the public key::

>>> key = jwk.JWK.generate(kty='EC', crv='P-256')
>>> key.export(private_key=False)   
'{"crv":"P-256","kty":"EC","x":"...","y":"..."}'

Import a P-256 Public Key::

>>> expkey = {"y":"VYlYwBfOTIICojCPfdUjnmkpN-g-lzZKxzjAoFmDRm8",
...           "x":"3mdE0rODWRju6qqU01Kw5oPYdNxBOMisFvJFH1vEu9Q",
...           "crv":"P-256","kty":"EC"}
>>> key = jwk.JWK(**expkey)

Import a Key from a PEM file::

>>> with open("public.pem", "rb") as pemfile:  
...     key = jwk.JWK.from_pem(pemfile.read())
