使用Python库解密令牌时出错，使用JAVA库创建

Question

已经有解密密钥和signed_key ..。只要知道python中的哪个库是正确的，就可以解码这个Java算法创建的JWT令牌。

加密:算法: RSA_OAEP，加密A128GCM令牌签名:算法: RS256

decrypt.py文件：

 from jwcrypto import jwt, jwk

    k = {"n": G_DECRYPTION_KEY, "kty": "RSA", "e":"A128GCM"} #, "alg":"RS256"} # "e":"AQAB"
    print 'k : %s \n'% k

    key = jwk.JWK(**k)
    print 'key : %s \n'% key

    decrypted_key = jwt.JWT(key=key, jwt= g_token)
    print 'decrypted_key : %s \n'% decrypted_key

    signed_key = jwt.JWT(key=key, jwt=decrypted_key.claims)
    print 'signed_key : %s'% signed_key

    signed_key.claims
    print 'signed_key.claims %s

‘

我正在收到的错误：

decrypted_key = jwt.JWT(key=key, jwt= g_token)
  File "C:\Python27\lib\site-packages\jwcrypto\jwt.py", line 204, in __init__
    self.deserialize(jwt, key)
  File "C:\Python27\lib\site-packages\jwcrypto\jwt.py", line 460, in deserialize
    self.token.deserialize(jwt, key)
  File "C:\Python27\lib\site-packages\jwcrypto\jwe.py", line 472, in deserialize
    self.decrypt(key)
  File "C:\Python27\lib\site-packages\jwcrypto\jwe.py", line 399, in decrypt
    'key' + repr(self.decryptlog))
InvalidJWEData: No recipient matched the provided key["Failed: [KeyError('p',)]"]

确保您的解密密钥与加密密钥相同。我认为这两个键都应该是来自jwcrypto包的jwcrypto的一个实例。
