The first has correct pkcs-1 padding and rsa.decrypt() run on it would succeed without error, whereas the second has byte 05 where rsa.decrypt() would expect to see a 02 byte.
# now decrypt 'manually' to see the padding RSAOAEPEnc ( message, pubkey ) print ( C) To decrypt the code, copy the output C and paste it along with the decryption key into decrytion. encode ( 'utf-8' ) pubkey enter public key tuple that was generated from keygeneration.py C rsa. It supports encryption and decryption, signing and verifying signatures, and key generation according to. rsa.encrypt(m) does not just compute pow(m, e, n), instead it computes pow(pkcs1_padding(m), e, n), and that inner pkcs1_padding function is not multiplicative.Ĭonsider a slight variation of the program to print out what happens to the plaintext: import rsaī_message = b'Journalist belong' # m should be in bytesĬ = rsa.encrypt(b_message, pub_key) # this is a byte numberĬ = int.from_bytes(c, byteorder='big') # turn bytes into int message input ( 'input message to encrypt: ' ) message message. Python-RSA is a pure-Python RSA implementation.
