I have requirement like while sending data to sever using SFTP i need to use crccheck/cheksum for data integrity. I am newbie to python. For SFTP file transfer i am using pysftp module and using put() i am transferring one by one file to server. 

    sftp.put(localpath=newlocalPath,remotepath=newremotePath,preserve_mtime=True)

So to check unsuccessful transfer, corrupted data transferred i need to implement CRCCheck. Is there any library for that in python? Any help please..

  • Thanks@Martin Prikryl . I used hashlib for generating md5 for local file and same i need to do for remote server. After that i need to match both local md5 and server md5. That i am facing IOError for remote fillepath due to sftp connection i think. haslib not able to connect remote path. Any suggestion please.. – somanath mishra Oct 09 '18 at 15:50
  • There's no suggestion. You cannot use hashlib with remote path. Read carefuly my answer to the duplicate question. – Martin Prikryl Oct 09 '18 at 16:04
