Crypt-LE The Crypt::LE module provides the functionality necessary to use Let's Encrypt API and generate free SSL certificates for your domains. It can also be used to generate private RSA keys or Certificate Signing Requests without resorting to openssl command line. INSTALLATION To install this module, run the following commands: perl Makefile.PL make make test make install PLUGINS Crypt::LE can be easily extended with custom plugins to handle Let's Encrypt challenges. See Crypt::LE::Challenge::Simple module as an example of such plugin. CLIENT Crypt::LE is shipped with a self-sufficient client for obtaining SSL certificates - le.pl. Run it without parameters to see how it is used. The client supports 'http' and 'dns' challenges out of the box. Usage example: le.pl --key account.key --csr domain.csr --csr-key domain.key --crt domain.crt --domains "www.domain.ext,domain.ext" --generate-missing That will generate an account key and a CSR if they are missing. If any of those files exists, they will just be loaded, so it is safe to re-run the client. The client application can be very easily extended with modules handling challenges and modules handling the process completion. For examples see Crypt::LE::Challenge::Simple and Crypt::LE::Complete::Simple. Related options of le.pl are: --handle-with --handle-params --handle-as --complete-with --complete-params Please note that parameters for --handle-params and --complete-params are expected to be valid JSON documents or to point to files containing valid JSON documents.
