title: How to decrypt data with botocore
body: <p>I am trying to print the decrypted data with the encrypted data to verify that it is correct.  </p>
  
  <pre><code>session = botocore.session.get_session()
      client = session.create_client('kms',region_name = 'us-east-1',aws_access_key_id = '[YOUR ACCESS KEY]',aws_secret_access_key = '[YOUR SECRET ACCESS KEY]')
  
  key_id = '[KEY ID]'
  plaintext='[FILEPATH\FILENAME.CSV]'
  
  
  ciphertext = client.encrypt(KeyId=key_id, Plaintext=plaintext)
  ciphertextblob = ciphertext
  decrypt_ciphertext = client.decrypt(CiphertextBlob = ciphertextblob)
  print('Ciphertext: ' ciphertext)
  print('Decrypted Ciphertext: 'decrypt_ciphertext)
  </code></pre>
  
  <p>When I run this code, the data is successfully encrypted, however, when it attempts to decrypt the data it gives me a Parameter Validation Failed error.  Does anyone know why it gives this error or how to fix it?</p>
