SSL stands for Secure Socket Layer and is an encryption protocol used to secure the communication on a network. SSL is used to encrypt the segment of network connections and it uses several methods to encrypt the data, depending on the goal which needs to be achieved: asymmetric cryptography for key exchange, symmetric encryption for privacy, and message authentication codes for message integrity. A certificate injection attack misuses the first type of cryptography algorithms: asymmetric cryptographic algorithms. Asymmetric cryptography  system requires two separate keys, one to lock or encrypt the plaintext, and one to unlock or decrypt the cyphertext. Neither key will do both functions. One of these keys is published or public and the other is kept private. If the lock/encryption key is the one published then the system enables private communication from the public to the unlocking key’s owner. If the unlock/decryption key is the one published then the system serves as a signature verifier of documents locked by the owner of the private key. Although in this latter case, since encrypting the entire message is relatively expensive computationally, in practice just a hash of the message is encrypted for signature verification purposes. In order to be able…
