ACME challenge mock server

## NAME

pebble-challtestsrv - ACME challenge mock server

## SYNOPSIS

**pebble** \[**-defaultIPv4** *string*\] \[**-defaultIPv6** *string*\] \[**-dns01** *string*\] \[**-http01** *string*\] \[**-https01** *string*\] \[**-management** *string*\] \[**-tlsalpn01** *string*\]

## DESCRIPTION

**pebble-challtestsrv** is a utility that responds to HTTP-01, DNS-01, and TLS-ALPN-01 ACME challenges.  It can also be used as a mock DNS server letting developers mock \`A\`, \`AAAA\`, \`CNAME\`, and \`CAA\` DNS data for specific hostnames.

Important note: The \`pebble-challtestsrv\` utility is for TEST USAGE ONLY.  It is trivially insecure, offering no authentication whatsoever.  Only use this library in a controlled test environment.
