NAME

       ntp-keygen - generate public and private keys

SYNOPSIS

       ntp-keygen  [  -deGgHIMnPT ] [ -c [RSA-MD2 | RSA-MD5 | RSA-SHA | RSA-SHA1 | RSA-MDC2 | RSA-RIPEMD160 | DSA-SHA | DSA-SHA1 ] ] [ -i name ] [
       -p password ] [ -S [ RSA | DSA ] ] [ -s name ] [ -v nkeys ]

DESCRIPTION

       This program generates cryptographic data files used by the NTPv4 authentication and identification schemes. It	generates  MD5	key  files
       used  in  symmetric  key  cryptography. In addition, if the OpenSSL software library has been installed, it generates keys, certificate and
       identity files used in public key cryptography. These files are used for cookie encryption, digital signature and challenge/response  iden-
       tification algorithms compatible with the Internet standard security infrastructure.

openssl_get_md_methods - Gets available digest methods

SYNOPSIS

       array openssl_get_md_methods ([bool  $aliases = false])

DESCRIPTION

	Gets a list of available digest methods.

PARAMETERS

	      o $aliases
		- Set to TRUE if digest aliases should be included within the returned array.

RETURN VALUES

	An array of available digest methods.

EXAMPLES

       Example #1

	      openssl_get_md_methods(3) example

	       Shows how the available digests might look, and also which aliases might be available.

	      <?php
	      $digests		   = openssl_get_md_methods();
	      $digests_and_aliases = openssl_get_md_methods(true);
	      $digest_aliases	   = array_diff($digests_and_aliases, $digests);

	      print_r($digests);

	      print_r($digest_aliases);

	      ?>

	      The above example will output something similar to:
