Secrets

Use IOptions<>

If you don't know how IOptions work, then go check out a tutorial. This is the recommended and supported way of storing configuration in Modular Pipelines.

Your options classes should be registered as IOptions.

If you have any sensitive/secret data stored in these classes, you can attribute your property with [SecretValue].

This attribute, combined with the IModuleLogger, means that if that value is ever attempted to be written to logs, it'll be censored out, so that secret values aren't visible to those unauthorised.

[SecretValue] supports scalar strings, character sequences such as char[], IEnumerable<char>, Memory<char>, and ReadOnlyMemory<char>, and collections of secret values. Character sequences are treated as one secret, while secret collections are masked item by item.

Example

public record MySettings
{
    [SecretValue]
    public string? ApiKey { get; set; }
}
