I use this code to create public and private keys:
import rsa
(pubkey, privkey) = rsa.newkeys(512)
And then convert it to PEM format:
exppub =pubkey.save_pkcs1(format='PEM')
exppriv = privkey.save_pkcs1(format='PEM')
When i encrypt massage with this keys:
message = 'hello Bob!'
crypto = rsa.encrypt(message, pubkey)
encrypted massage is like this:
"@\xc4\xb2\x14r\xf1x\xb8\xb2\t;\x9a:\x1dl\x11\xe2\x10\xa9E\xee\x8b\xac\xd0\xd3Y\xfb}\xd9@\xdd\x0c\xa5\xd2\xfc1\xd6\x06\xf0\xb8\x944\xe1\xc2r\xe5anyq\xac\xdfh\xeb\x10\x80\x98\xa1\xee'\xe6hpi"
and i know it should be like this:
SEcPB1mYNrfeE4zP4RI3z2K4Rh9HDNfPhuF28IyxHFjEOJ9Z+1zdIwPF0jsJGQDJyKpAju7dcYueHHXXeH8d+w==
How can i change the format of this?
I can't help with the crypto, but I can help make it more likely that
someone will be able to help.
1) Always specify the Python version and OS when you start a new thread.
2) When you show data, show how you're displaying that data. You have
two strings, but the one is apparently a repr() of a string, while the
other is not. And you don't specify how you "know it should be like
this." Are you running some other encryption utility that gives you
that message? Be specific. Something like:
crypto = rsa.enc....
print( repr(crypto) )
displays as
"@\xc4\xb2\x...
but running mycrypto.exe key="xyzyzzyzyzy" data="hello Bob!"
displays as
SEcPB1mYNrf...
Have you tried decrypting the encrypted message, using the privkey? Did
it in fact produce the original? Could it be that the error is in how
you're transporting the public key to your reference program?
It might also be useful to show the types of each of the variables. For
example, you probably cannot encrypt text, but only binary. So you
might need to explicitly encode the text "hello Bob!" before encrypting it.
