NAME

       IO::Socket::SSL::Utils -- loading, storing, creating certificates and keys

SYNOPSIS

	   use IO::Socket::SSL::Utils;
	   my $cert = PEM_file2cert('cert.pem');
	   my $string = PEM_cert2string($cert);
	   CERT_free($cert);

	   my $key = KEY_create_rsa(2048);
	   PEM_string2file($key);
	   KEY_free($key);

DESCRIPTION

       This module provides various utility functions to work with certificates and private keys, shielding some of the complexity of the
       underlying Net::SSLeay and OpenSSL.

FUNCTIONS

       o   Functions converting between string or file and certificates and keys.  They croak if the operation cannot be completed.

	   PEM_file2cert(file) -> cert
	   PEM_cert2file(cert,file)
	   PEM_string2cert(string) -> cert
	   PEM_cert2string(cert) -> string
	   PEM_file2key(file) -> key
	   PEM_key2file(key,file)
	   PEM_string2key(string) -> key
	   PEM_key2string(key) -> string
       o   Functions for cleaning up.  Each loaded or created cert and key must be freed to not leak memory.

	   CERT_free(cert)
	   KEY_free(key)
       o   KEY_create_rsa(bits) -> key

	   Creates an RSA key pair, bits defaults to 1024.

       o   CERT_asHash(cert) -> hash

	   Extracts the information from the certificate into a hash:

	   serial  The serial number

	   version Certificate version, usually 2 (x509v3)

	   subject Hash with the parts of the subject, e.g. commonName, countryName, organizationName, stateOrProvinceName, localityName.

	   subjectAltNames
		   Array with list of alternative names. Each entry in the list is of "[type,value]", where "type" can be OTHERNAME, EMAIL, DNS,
		   X400, DIRNAME, EDIPARTY, URI, IP or RID.

	   not_before, not_after
		   The time frame, where the certificate is valid, as time_t, e.g. can be converted with localtime or similar functions.

       o   CERT_create(hash) -> cert

	   Creates a certificate based on the given hash.  Additionally to the information described in "CERT_asHash" the following keys can be
	   given:

	   CA true|false
		   if true declare certificate as CA, defaults to false

	   key key use given key as key for certificate, otherwise a new one will be generated

	   issuer_cert cert
		   set issuer for new certificate

	   issuer_key key
		   sign new certificate with given key

	   If not all necessary information are given some will have usable defaults, e.g.

	   not_before defaults to the current time
	   not_after defaults to 365 days in the future
	   subject has a default pointing to IO::Socket::SSL
	   version defaults to 2 (x509v3)
	   serial will be a random number
