Signature verification

[gontajones]

Yep, I run this code in my step 4 and it returned True.

Yeah but the problem for me is in line 17 i am hard coding the key as “BEGIN PUBLIC KEY ”+ hardcoded key value+”END PUBLIC KEY”. But i am getting false

The key that you are mentioning is a private key, the function needs the public key (and it reads it from file).
Your public key file should looks like:

Output:
ssh-rsa AAAAB3N...ns3bhHGhjR6XCJcFik9K/ne+uhSy40Ij user@linux

Another question, how are you generating the signature?
