XML::Compile::WSS::Signature - WSS in CICS-TS style
XML::Compile::WSS::Signature is a XML::Compile::WSS
my $wss = XML::Compile::WSS::Signature->new ( ... some required params, see below );
WARNING: under development!
The generic Web Service Security protocol is implemented by the super class XML::Compile::WSS. This extension implements Signatures.
Only digest algorithms which are provided via the Digest module are supported for the elements to be signed.
Only a limited subset of signing (algoritm, hash) combinations are supported. Lower on this page, you find details about each of the provided signing implementations.

The algorithm to be used for canonicalization of some component. These constants are pre-defined with nice
C14N_* names in XML::Compile::C14N::Util.
The algorithm used to sign the body digest, when sending. The digest name is an ugly constant which has a nice
DSIG_* alias defined in XML::Compile::WSS::Util.
The exact features of this option depend on the sign_method. Usually, you can specify an OBJECT which contains the key, or STRING or FILENAME to create such an object.
In some cases, the public key can be derived from the private key.
The KEYTYPE must be specified in the SignedInfo. It depends on the
sign_method which default is taken.
How to publish the public key. The
INCLUDE_BY_REF constant (currently the only one supported) will add the key as BinarySecurityToken in the message, plus a keyinfo structure with a reference to that token.
Returns the default DIGEST constant, as set with new(digest_method).
This must be a full constant name, as provided by XML::Compile::WSS::Util. They are listed under export tags
Digest the text (passed as TEXTREF for reasons of performance) into a binary string.
Returns information about canonicalization method CANON. By default the algoritm of defaultCanonMethod().
Returns the default Canonicalization method as constant.
Returns an ARRAY with the prefixes to be used in canonicalization.
-Option--Default id unique
The base of this whole security protocol is crypto-signing the messages, so you will always need to specify some parameters for new().
my $wss = XML::Compile::WSS::Signature->new ( sign_method => DSIG_$algo , ...parameters for $algo... );
When the algorithm is known (see the next sections of this chapter), then the parameters will be used to produce the CODE which will do the signing.
The signing algorithm uses Crypt::OpenSSL::RSA. According to its manual-page, the current implementation is limited to
DSIG_RSA_SHA1 DSIGM_RSA_MD5 DSIGM_RSA_SHA256 DSIGM_RSA_SHA384 DSIGM_RSA_SHA512
It could support some RSA_RIPEMD160, however there is no official constant for that in the standards.
my $wss = XML::Compile::WSS::Signature->new ( sign_method => DSIG_RSA_SHA1 , private_key => $privkey , public_key_type => XTP10_X509 # default , public_key => $pubkey # default from $privkey , public_key_uri => '#public-key' # default , publish_pubkey => 'INCLUDE_BY_REF' # default );
You have to provide the private key. There are various ways to do that. Valid values for
$privkey in above example:
containing the private key, for instance created via its
The private key is read from the FILENAME. Typically, the filename ends on ".pem".
The private key is provided as string, formatted the same way as a PEM file looks.
public_key_type, you specify the format of the public key. By default, the
XTP10_X509 is taken. You may also specify other
XTP10_* constants XML::Compile::WSS::Util tag-group
public_key, you have the same options as for the
private_key option, although the object is created with new_public_key this time. If the $pubkey is not provided, the $privkey object is used.
publish_pubkey can be a prefined constant or a CODE reference. This function will be called then the
wsse:Security structure is being constructed. It puts the public key information in the right Perl structure to be translated into XML automatically. The only defined constant is
