Use module Crypto.Cipher.PKCS1_OAEP instead

Hi everyone,

I got an error in this class while using jira rest api authentication, until now it worked well; but today i got an error.

class SignatureMethod_RSA_SHA1(oauth.SignatureMethod):
 name = 'RSA-SHA1'

def signing_base(self, request, consumer, token):
 if not hasattr(request, 'normalized_url') or request.normalized_url is None:
 raise ValueError("Base URL for request is not set.")

sig = (
 oauth.escape(request.method),
 oauth.escape(request.normalized_url),
 oauth.escape(request.get_normalized_parameters()),
 )

key = '%s&' % oauth.escape(consumer.secret)
 if token:
 key += oauth.escape(token.secret)
 raw = '&'.join(sig)
 return key, raw

def sign(self, request, consumer, token):
 """Builds the base signature string."""
 key, raw = self.signing_base(request, consumer, token)

with open('***.pem', 'r') as f:
 data = f.read()
 privateKeyString = data.strip()

privatekey = keyfactory.parsePrivateKey(privateKeyString)
 signature = privatekey.hashAndSign(raw)

return base64.b64encode(signature)

The error:

 raise NotImplementedError("Use module Crypto.Cipher.PKCS1_OAEP instead")
NotImplementedError: Use module Crypto.Cipher.PKCS1_OAEP instead

Any suggestion to fix this error?

Thanks.
