Method Detail

addSignature

public static XSSignature addSignature(oracle.security.xmlsec.util.XMLElement msg,
                                       java.lang.String referenceTargetID,
                                       java.lang.String signatureMethod,
                                       java.lang.String c14nMethod,
                                       java.lang.String digestMethod,
                                       java.lang.String[] nsURIs,
                                       java.lang.String[] localNames)

Creates a new XML-DSIG Signature element and inserts it into the given message, replacing any exisiting XML-DSIG Signature element. This method does not compute the SignatureValue or create the KeyInfo child element for the Signature element.

Note: The SHA-1 algorithm is used for the Reference's DigestMethod.

Parameters:

msg - The message the Signature element to be added on.

referenceTargetID - The ID attribute value of the element to be signed.

signatureMethod - The value of the Algorithm attribute of the SignatureMethod element contained within the new Signature element's SignedInfo child element.

c14nMethod - The value of the Algorithm attribute of the CanonicalizationMethod element contained within the new Signature element's SignedInfo child element .

digestMethod - The value of the Algorithm attribute of the DigestMethod element of the new Signature's Reference element.

localNames - The ordered set of the local names of all the child elements precede the Signature element in the schema for the element represented by the message.

nsURIs - The ordered set of the namespace URIs of the child elements precede the Signature element in the schema for the element represented by the message.

Returns:

The new oracle.security.xmlsec.dsig.XSSignature object

signURL

public static java.lang.String signURL(java.lang.String msg,
                                       java.security.PrivateKey key,
                                       java.lang.String sigAlgURI)
                                throws SigningException

Computes a signature over the given message, using the given private key and signature algorithm, and returns a URL-encoded string suitable for use as a URL query parameter.

Parameters:

msg - The data to be signed.

key - The private signing key.

sigAlgURI - The URI identifying the signature algorithm to use.

Throws:

SigningException - If an error occurs computing the signature.
