NAME
OpenCA::OpenSSL - Perl Crypto Extention to OpenSSLSYNOPSIS
use OpenCA::OpenSSL;
DESCRIPTION
This Perl Module implements an interface to the openssl backend program. It actually uses the openssl command and it is not fully integrated as PERL/C mixture.Passing parameters to functions should be very simple as them have no particular order and have, often, self-explaining name. Each parameter should be passed to the function like this:
... ( NAME=>VALUE, NAME=>VALUE, ... );
FUNCTIONS
sub new () - Creates a new Class instance.
This functions creates a new instance of the class. It accepts
only one parameter: the path to the backend command (openssl).
This is due because if it cannot find the openssl command it
will return an uninitialized class (default value is /usr/bin/
openssl which may not fit many distributions/OSs)
EXAMPLE:
my $openssl->new OpenCA::OpenSSL( $path );
sub setParams () - Set internal module variables.
This function can handle the internal module data such as the
backend path or the tmp dir. Accepted parameters are:
SHELL - Path to the openssl command.
CONFIG - Path to the openssl config file.
TMPDIR - Temporary files directory.
STDERR - Where to redirect the STDERR file.
(*) - Optional parameters;
EXAMPLE:
$openssl->setParams( SHELL=>'/usr/local/ssl/bin/openssl',
CONFIG=>$ca/stuff/openssl.cnf,
TMPDIR=>'/tmp',
STDERR=>'/dev/null' );
sub errno () - Get last command errno value.
This functions returns last operation's errno value. Non
zero value means there has been an error.
EXAMPLE:
print $openssl->errno;
sub errval () - Get last command errval value.
This functions returns last operation's errval value. This
value usually has a brief error description.
EXAMPLE:
print $openssl->errval;
sub genKey () - Generate a private Key.
This functions let you generate a new private key. Accepted
parameters are:
BITS - key lengh in bits(*);
OUTFILE - Output file name(*);
ALGORITHM - Encryption Algorithm to be used(*);
PASSWD - Password to be used when encrypting(*);
(*) - Optional parameters;
EXAMPLE:
my $key = $openssl->genKey( BITS=>1024 );
sub genReq () - Generate a new Request.
This function generate a new certificate request. Accepted
parameters are:
OUTFILE - Output file(*);
KEYFILE - File containing the key;
PASSWD - Password to decript key (if needed) (*);
DN - Subject list (as required by openssl, see
the openssl.cnf doc on policy);
SUBJECT - DN string (use this instead of passing separate
attributes list)(*);
(*) - Optional parameters;
EXAMPLE:
my $req = $openssl->genReq( KEYFILE=>"00_key.pem",
DN => [ "madwolf@openca.org","Max","","","" ] );
my $req = $openssl->genReq( KEYFILE=>"00_key.pem",
SUBJECT => "CN=Madwolf, O=OpenCA, C=IT" );
sub genCert () - Generate a certificate from a request.
This function let you generate a new certificate starting
from the request file. It is used for self-signed certificate
as it simply converts the request into a x509 structure.
Accepted parameters are:
OUTFILE - Output file(*);
KEYFILE - File containing the private key;
REQFILE - Request File;
PASSWD - Password to decrypt private key(*);
DAYS - Validity days(*);
(*) - Optional parameters;
EXAMPLE:
$cert = $openssl->genCert( KEYFILE=>"priv_key.pem",
REQFILE=>"req.pem",
DAYS=>"720" );
sub crl2pkcs7 () - Convert a crl and/or certs into pkcs7 structure.
This function converts certificates (optional) and a crl
(also optional) into a pkcs7 structure. It is used to build
strucutures to load certificates/crls into some browsers.
Accepted parameters are:
DATA - PEM|DER formatted CRL(*);
INFORM - Input crl format (DER|PEM) (*);
OUTFORM - Output pkcs7 structure format (DER|PEM) (*);
INFILE - Input crl file (*);
OUTFILE - Output pkcs7 file (*);
CERTSLIST - List of files containing certificates to
be added to the pkcs7 structure (*);
(*) - Optional parameters;
EXAMPLE:
$pkcs7 = $openssl->crl2pkcs7( DATA=>$crl->getPEM(),
CERTSLIST=>[ "cert1.pem", "cert2.pem" ]);
sub dataConvert () - Convert data to different format.
This functions will convert data you pass to another format. Ir
requires you to provide with the data's type and IN/OUT format.
Accepted parameters are:
DATA - Data to be processed;
INFILE - Data file to be processed (one of DATA and
INFILE are required and exclusive);
KEYFILE - file with the priv. key (* PEM to PKCS12 only).
Not needed if key is presented in DATA or INFILE too.
DATATYPE - Data type ( CRL | CERTIFICATE | REQUEST );
OUTFORM - Output format (PEM|DER|NET|TXT)(*);
INFORM - Input format (PEM|DER|NET|TXT)(*);
OUTFILE - Output file(*);
PASSWD - priv. key password (* PKCS12 to PEM only)
omitting the PASSWD leads into an unencrypted priv. key
ALGO - des,des3 or idea. Default is des3 encryption for priv. key
P12PASSWD - PKCS12 export password (* only needed for PKCS12)
NOKEYS - extract only the certificate (* PKCS12 to PEM only)
No need for the PASSWD parameter with this option.
CACERT - CA-certificate to add if OUTFORM is PKCS#12
(*) - Optional parameters;
EXAMPLES:
# PEM file to TXT format
print $openssl->dataConvert( INFILE=>"crl.pem",
OUTFORM=>"TXT" );
# PEM file to PKCS12 format, priv key will be des3 encrypted
print $openssl->dataConvert( INFILE=>"crl.pem",
DATATYPE=>'CERTIFICATE',
OUTFORM=>"PKCS12",
PASSWD=>$pem_pass,
P12PASSWD=>$export_pass );
# PKCS12 data to PEM formated certificate (no key)
print $openssl->dataConvert( DATA=>$pkcs12_cert,
DATATYPE=>'CERTIFICATE',
INFORM=>"PKCS12",
NOKEYS=>1,
P12PASSWD=>$export_pass );
