哪个Python JOSE库支持嵌套JWT (signed+encrypted)？

Question

我研究了python-jose和jose，但似乎都不支持加密签名的JWT。例如，"jose“库支持单独签名和加密，而不需要嵌套它们。

我是不是遗漏了什么，比如在库之外嵌套JWTs可能相当容易？如果是这样，请分享实现这一点的技巧，以使结果格式正确。

jwcrypto支持嵌套的JWS和JWE。

要签名，然后进行加密：

# Load your RSA pub and private keys
pubKey = jwk.JWK().from_pyca(serializedPublicKey)
privateKey = jwk.JWK().from_pyca(serializedPrivateKey)

# your JWT claims go here
claims = {
    # JWT claims in JSON format
          }
# sign the JWT
# specify algorithm needed for JWS
header = {
          u'alg' : 'RS256', 
          'customSigHeader':'customHeaderContent'
          }
# generate JWT
T = jwt.JWT(header, claims)
# sign the JWT with a private key
T.make_signed_token(privateKey)
# serialize it
signed_token = T.serialize(compact=True)

# JWE algorithm in the header
eprot = {
    'alg': "RSA-OAEP", 
    'enc': "A128CBC-HS256",
     'customEncHeader':'customHeaderContent'
     }   
E = jwe.JWE(signed_token, json_encode(eprot))
# encrypt with a public key
E.add_recipient(pubKey)#
# serialize it
encrypted_signed_token = E.serialize(compact=True)

要解密和验证签名：

#Decrypt and Verify signature
E = jwe.JWE()
# deserialize and decrypt
E.deserialize(encrypted_signed_token, key=privateKey)
raw_payload = E.payload
# verify signature
S = jws.JWS()
S.deserialize(raw_payload, key=pubKey)
final_payload = S.payload
