How to create a WIF private key.
A WIF private key is a standard private key, but with a few added extras:
- Version Byte prefix - Indicates which network the private key is to be used on.
- Compression Byte suffix (optional) - Indicates if the private key is used to create a compressed public key.
- Checksum - Useful for detecting errors/typos when you type out your private key.
This is all then converted to Base58, which shortens the entire thing and makes it easier to transcribe...
