I am trying to encrypt and decrypt files RSA library. I’m always successful with the encryption but i get an overflow error during the decryption I get an exception saying “OverflowError: 64 bytes needed for message, but there is only space for 53” here is the code below;

import rsa
pubkey,privekey= rsa.newkeys(512)

path = "C:\Users\PC\Documents\Document.rtf"
with open (path,'rb') as thefile:
    contents = thefile.read()
    contents_encryp = rsa.encrypt(contents,pubkey)
with open(path, 'wb') as thefile:
    thefile.write(contents_encryp)

here is the decryption code below;

import rsa
from encryptor import contents_encryp,privekey
path = "C:\Users\PC\Documents\Document.rtf"
with open (path,'rb') as thefile:
    contents = thefile.read()
    contents_decryp = rsa.decrypt(contents_encryp,privekey)
with open(path, 'wb') as thefile:
    thefile.write(contents_decryp)
