Starsinic to enable setting the private key, rather than always having it generated. - Removed unnecessary mp2bin function. 0.02 2001.04.24 - Fixed broken test program (still need more tests). 0.01 2001.03.22 - original version; created by h2xs 1.19 ./Crypt-DH-0.07/inc/0000755000175100010010000000000011775536022011245 5ustar SVN./Crypt-DH-0.07/inc/Devel/0000755000175100010010000000000011775536022012304 5ustar SVN./Crypt-DH-0.07/inc/Devel/CheckLib.pm0000755000175100010010000003625111775535600014321 0ustar SVN# $Id: CheckLib.pm,v 1.25 2008/10/27 12:16:23 drhyde Exp $ package # Devel::CheckLib; use 5.00405; #postfix foreach use strict; use vars qw($VERSION @ISA @EXPORT); $VERSION = '0.98'; use Config qw(%Config); use Text::ParseWords 'quotewords'; use File::Spec; use File::Temp; require Exporter; @ISA = qw(Exporter); @EXPORT = qw(assert_lib check_lib_or_exit check_lib); # localising prevents the warningness leaking out of this module local $^W = 1; # use warnings is a 5.6-ism _findcc(); # bomb out early if there's no compiler =head1 NAME Devel::CheckLib - check that a library is available =head1 DESCRIPTION Devel::CheckLib is a perl module that checks whether a particular C library and its headers are available. =head1 SYNOPSIS use Devel::CheckLib; check_lib_or_exit( lib => 'jpeg', header => 'jpeglib.h' ); check_lib_or_exit( lib => [ 'iconv', 'jpeg' ] ); # or prompt for path to library and then do this: check_lib_or_exit( lib => 'jpeg', libpath => $additional_path ); =head1 USING IT IN Makefile.PL or Build.PL If you want to use this from Makefile.PL or Build.PL, do not simply copy the module into your distribution as this may cause problems when PAUSE and search.cpan.org index the distro. Instead, use the use-devel-checklib script. =head1 HOW IT WORKS You pass named parameters to a function, describing to it how to build and link to the libraries. It works by trying to compile some code - which defaults to this: int main(void) { return 0; } and linking it to the specified libraries. If something pops out the end which looks executable, it gets executed, and if main() returns 0 we know that it worked. That tiny program is built once for each library that you specify, and (without linking) once for each header file. If you want to check for the presence of particular functions in a library, or even that those functions return particular results, then you can pass your own function body for main() thus: check_lib_or_exit( function => 'foo();if(libversion() > 5) return 0; else return 1;' incpath => ... libpath => ... lib => ... header => ... ); In that case, it will fail to build if either foo() or libversion() don't exist, and main() will return the wrong value if libversion()'s return value isn't what you want. =head1 FUNCTIONS All of these take the same named parameters and are exported by default. To avoid exporting them, C. =head2 assert_lib This takes several named parameters, all of which are optional, and dies with an error message if any of the libraries listed can not be found. B: dying in a Makefile.PL or Build.PL may provoke a 'FAIL' report from CPAN Testers' automated smoke testers. Use C instead. The named parameters are: =over =item lib Must be either a string with the name of a single library or a reference to an array of strings of library names. Depending on the compiler found, library names will be fed to the compiler either as C<-l> arguments or as C<.lib> file names. (E.g. C<-ljpeg> or C) =item libpath a string or an array of strings representing additional paths to search for libraries. =item LIBS a C-style space-seperated list of libraries (each preceded by '-l') and directories (preceded by '-L'). This can also be supplied on the command-line. =back And libraries are no use without header files, so ... =over =item header Must be either a string with the name of a single header file or a reference to an array of strings of header file names. =item incpath a string or an array of strings representing additional paths to search for headers. =item INC a C-style space-seperated list of incpaths, each preceded by '-I'. This can also be supplied on the command-line. =back =head2 check_lib_or_exit This behaves exactly the same as C except that instead of dieing, it warns (with exactly the same error message) and exits. This is intended for use in Makefile.PL / Build.PL when you might want to prompt the user for various paths and things before checking that what they've told you is sane. If any library or header is missing, it exits with an exit value of 0 to avoid causing a CPAN Testers 'FAIL' report. CPAN Testers should ignore this result -- which is what you want if an external library dependency is not available. =head2 check_lib This behaves exactly the same as C except that it is silent, returning false instead of dieing, or true otherwise. =cut sub check_lib_or_exit { eval 'assert_lib(@_)'; if($@) { warn $@; exit; } } sub check_lib { eval 'assert_lib(@_)'; return $@ ? 0 : 1; } sub assert_lib { my %args = @_; my (@libs, @libpaths, @headers, @incpaths); # FIXME: these four just SCREAM "refactor" at me @libs = (ref($args{lib}) ? @{$args{lib}} : $args{lib}) if $args{lib}; @libpaths = (ref($args{libpath}) ? @{$args{libpath}} : $args{libpath}) if $args{libpath}; @headers = (ref($args{header}) ? @{$args{header}} : $args{header}) if $args{header}; @incpaths = (ref($args{incpath}) ? @{$args{incpath}} : $args{incpath}) if $args{incpath}; # work-a-like for Makefile.PL's LIBS and INC arguments # if given as command-line argument, append to %args for my $arg (@ARGV) { for my $mm_attr_key (qw(LIBS INC)) { if (my ($mm_attr_value) = $arg =~ /\A $mm_attr_key = (.*)/x) { # it is tempting to put some \s* into the expression, but the # MM command-line parser only accepts LIBS etc. followed by =, # so we should not be any more lenient with whitespace than that $args{$mm_attr_key} .= " $mm_attr_value"; } } } # using special form of split to trim whitespace if(defined($args{LIBS})) { foreach my $arg (split(' ', $args{LIBS})) { die("LIBS argument badly-formed: $arg\n") unless($arg =~ /^-l/i); push @{$arg =~ /^-l/ ? \@libs : \@libpaths}, substr($arg, 2); } } if(defined($args{INC})) { foreach my $arg (split(' ', $args{INC})) { die("INC argument badly-formed: $arg\n") unless($arg =~ /^-I/); push @incpaths, substr($arg, 2); } } my ($cc, $ld) = _findcc(); my @missing; my @wrongresult; my @use_headers; # first figure out which headers we can't find ... for my $header (@headers) { push @use_headers, $header; my($ch, $cfile) = File::Temp::tempfile( 'assertlibXXXXXXXX', SUFFIX => '.c' ); my $ofile = $cfile; $ofile =~ s/\.c$/$Config{_o}/; print $ch qq{#include <$_>\n} for @use_headers; print $ch qq{int main(void) { return 0; }\n}; close($ch); my $exefile = File::Temp::mktemp( 'assertlibXXXXXXXX' ) . $Config{_exe}; my @sys_cmd; # FIXME: re-factor - almost identical code later when linking if ( $Config{cc} eq 'cl' ) { # Microsoft compiler require Win32; @sys_cmd = ( @$cc, $cfile, "/Fe$exefile", (map { '/I'.Win32::GetShortPathName($_) } @incpaths), "/link", @$ld ); } elsif($Config{cc} =~ /bcc32(\.exe)?/) { # Borland @sys_cmd = ( @$cc, @$ld, (map { "-I$_" } @incpaths), "-o$exefile", $cfile ); } else { # Unix-ish: gcc, Sun, AIX (gcc, cc), ... @sys_cmd = ( @$cc, @$ld, $cfile, (map { "-I$_" } @incpaths), "-o", "$exefile" ); } warn "# @sys_cmd\n" if $args{debug}; my $rv = $args{debug} ? system(@sys_cmd) : _quiet_system(@sys_cmd); push @missing, $header if $rv != 0 || ! -x $exefile; _cleanup_exe($exefile); unlink $ofile if -e $ofile; unlink $cfile; } # now do each library in turn with headers my($ch, $cfile) = File::Temp::tempfile( 'assertlibXXXXXXXX', SUFFIX => '.c' ); my $ofile = $cfile; $ofile =~ s/\.c$/$Config{_o}/; print $ch qq{#include <$_>\n} foreach (@headers); print $ch "int main(void) { ".($args{function} || 'return 0;')." }\n"; close($ch); for my $lib ( @libs ) { my $exefile = File::Temp::mktemp( 'assertlibXXXXXXXX' ) . $Config{_exe}; my @sys_cmd; if ( $Config{cc} eq 'cl' ) { # Microsoft compiler require Win32; my @libpath = map { q{/libpath:} .

Diffie-Hellman is an algorithm by which two parties can agree on a shared secret key, known only to them. The secret is negotiated over an insecure network without the two parties ever passing the actual shared secret, or their private keys, between them. =head1 THE ALGORITHM The algorithm generally works as follows: Party A and Party B choose a property I

Diffie-Hellman is an algorithm by which two parties can agree on a shared secret key, known only to them. The secret is negotiated over an insecure network without the two parties ever passing the actual shared secret, or their private keys, between them. THE ALGORITHM The algorithm generally works as follows: Party A and Party B choose a property *p* and a property *g*; these properties are shared by both parties. Each party then computes a random private key integer *priv_key*, where the length of *priv_key* is at most (number of bits in *p*) - 1. Each party then computes a public key based on *g*, *priv_key*, and *p*; the exact value is g ^ priv_key mod p The parties exchange these public keys. The shared secret key is generated based on the exchanged public key, the private key, and *p*. If the public key of Party B is denoted *pub_key_B*, then the shared secret is equal to pub_key_B ^ priv_key mod p The mathematical principles involved insure that both parties will generate the same shared secret key. More information can be found in PKCS #3 (Diffie-Hellman Key Agreement Standard): http://www.rsasecurity.com/rsalabs/pkcs/pkcs-3/ USAGE *Crypt::DH* implements the core routines needed to use Diffie-Hellman key exchange. To actually use the algorithm, you'll need to start with values for *p* and *g*; *p* is a large prime, and *g* is a base which must be larger than 0 and less than *p*. *Crypt::DH* uses *Math::BigInt* internally for big-integer calculations. All accessor methods (*p*, *g*, *priv_key*, and *pub_key*) thus return *Math::BigInt* objects, as does the *compute_secret* method. The accessors, however, allow setting with a scalar decimal string, hex string (^0x), Math::BigInt object, or Math::Pari object (for backwards compatibility). $dh = Crypt::DH->new([ %param ]). Constructs a new *Crypt::DH* object and returns the object. *%param* may include none, some, or all of the keys *p*, *g*, and *priv_key*. $dh->p([ $p ]) Given an argument *$p*, sets the *p* parameter (large prime) for this *Crypt::DH* object. Returns the current value of *p*. (as a Math::BigInt object) $dh->g([ $g ]) Given an argument *$g*, sets the *g* parameter (base) for this *Crypt::DH* object. Returns the current value of *g*. $dh->generate_keys Generates the public and private key portions of the *Crypt::DH* object, assuming that you've already filled *p* and *g* with appropriate values. If you've provided a priv_key, it's used, otherwise a random priv_key is created using either Crypt::Random (if already loaded), or /dev/urandom, or Perl's rand, in that order. $dh->compute_secret( $public_key ) Given the public key *$public_key* of Party B (the party with which you're performing key negotiation and exchange), computes the shared secret key, based on that public key, your own private key, and your own large prime value (*p*). The historical method name "compute_key" is aliased to this for compatibility. $dh->priv_key([ $priv_key ]) Returns the private key. Given an argument *$priv_key*, sets the *priv_key* parameter for this *Crypt::DH* object. $dh->pub_key Returns the public key.
