The Python Crypto Library is a third-party library that provides cryptographic primitives and algorithms for Python programming language. It is also known as the PyCrypto library. The library supports a wide range of cryptographic algorithms and protocols, including symmetric and asymmetric encryption, digital signatures, hash functions, key derivation functions, and more.
Fix the broken script rsa_sign.py, to enable it to sign the message hash correctly using the provided key private.pem.
Note that the key private.pem was generated using the following command:
key = RSA.generate(2048)
pem = key.export_key(format='PEM', passphrase='dees')
f = open('private.pem','wb')
f.write(pem)
f.close()
- Usage:
sudo python3 rsa_sign.py - Your script is expected to print the signature of the hash of the plaintext message.
- Your program will be manually tested for correctness.
- Your program should execute with no errors and warnings.
