A simple overview of Zig's std.log for Zig v0.12.0 or higher

Logging functionality that supports:

• If a log message should be printed is determined at comptime, meaning zero overhead for unprinted messages (so just leave the code peppered with debug logs, but when it makes sense scope them; so downstream users can filter them out)
• Scoped log messages
• Different log levels per scope
• Overrideable log output (write to file, database, etc.)
• All the standard std.fmt formatting magic

Basic Usage:

Create Root CA (Done once)

Create Root Key

Attention: this is the key used to sign the certificate requests, anyone holding this can sign certificates on your behalf. So keep it in a safe place!

openssl genrsa -des3 -out rootCA.key 4096
