Public Private Key Encrypytion

It turns out with cryptography that one can have this pattern:

• Generate a private-public key pair

  • The public key can be given out freely

  • Other software can then generate a challenge, that only the software that holds the private key can answer.

• So when you deal with software like GIT that uses ssh as a secure mechanism to authenticate

  • It is necessary to generate a key pair and then share the public key with the software that holds the git repo you want authenticate with.
