Integrate `go-git` into the application, and use it to `git clone` cheatsheets when the installer runs. Previously, the installer required that `git` be installed on the system `PATH`, so this change has to big advantages: 1. It removes that system dependency on `git` 2. It paves the way for implementing the `--update` command Additionally, `cheat` now performs a `--depth=1` clone when installing cheatsheets, which should at least somewhat improve installation times (especially on slow network connections).

Package x448 provides Diffie-Hellman functions as specified in RFC-7748.
|
|
|
|
Validation of public keys.
|
|
|
|
The Diffie-Hellman function, as described in RFC-7748 [1], works for any
|
|
public key. However, if a different protocol requires contributory
|
|
behaviour [2,3], then the public keys must be validated against low-order
|
|
points [3,4]. To do that, the Shared function performs this validation
|
|
internally and returns false when the public key is invalid (i.e., it
|
|
is a low-order point).
