NAME
    XML::Enc - XML Encryption

METHODS
  new( ... )
    Constructor. Creates an instance of the XML::Enc object

    Arguments:

    key Filename of the private key to be used for decryption.

    cert
        Filename of the public key to be used for encryption.

    no_xml_declaration
        Do not return the XML declaration if true (1). Return it if false
        (0). This is useful for decrypting documents without the declaration
        such as SAML2 Responses.

    data_enc_method
        Specify the data encryption method to be used. Supported methods
        are:

        Used in encryption. Optional. Default method: aes256-cbc

        *   tripledes-cbc
            <https://www.w3.org/TR/2002/REC-xmlenc-core-20021210/Overview.ht

        *   aes256-cbc
            <https://www.w3.org/TR/2002/REC-xmlenc-core-20021210/Overview.ht
            ml#aes256-cbc>

        *   aes128-gcm <https://www.w3.org/TR/xmlenc-core/#aes128-gcm>

        *   aes192-gcm <https://www.w3.org/TR/xmlenc-core/#aes192-gcm>

        *   aes256-gcm <https://www.w3.org/TR/xmlenc-core/#aes256-gcm>

    key_transport
        Specify the encryption method to be used for key transport.
        Supported methods are:

        Used in encryption. Optional. Default method: rsa-oaep-mgf1p

        *   rsa-1_5
            <https://www.w3.org/TR/2002/REC-xmlenc-core-20021210/Overview.ht
            ml#rsa-1_5>

        *   rsa-oaep-mgf1p
            <https://www.w3.org/TR/2002/REC-xmlenc-core-20021210/Overview.ht
            ml#rsa-oaep-mgf1p>

        *   rsa-oaep <http://www.w3.org/2009/xmlenc11#rsa-oaep>

    oaep_mgf_alg
        Specify the Algorithm to be used for rsa-oaep. Supported algorithms
        are:

        Used in encryption. Optional. Default method: mgf1sha1

        *   mgf1sha1 <http://www.w3.org/2009/xmlenc11#mgf1sha1>

        *   mgf1sha224 <http://www.w3.org/2009/xmlenc11#mgf1sha224>

        *   mgf1sha265 <http://www.w3.org/2009/xmlenc11#mgf1sha256>

        *   mgf1sha384 <http://www.w3.org/2009/xmlenc11#mgf1sha384>

        *   mgf1sha512 <http://www.w3.org/2009/xmlenc11#mgf1sha512>

    oaep_params
        Specify the OAEPparams value to use as part of the mask generation
        function (MGF). It is optional but can be specified for rsa-oaep and
        rsa-oaep-mgf1p EncryptionMethods.

        It is base64 encoded and stored in the XML as OAEPparams.

        If specified you MAY specify the oaep_label_hash that should be
        used. You should note that not all implementations support an
        oaep_label_hash that differs from that of the MGF specified in the
        xenc11:MGF element or the default MGF1 with SHA1.

        The oaep_label_hash is stored in the DigestMethod child element of
        the EncryptionMethod.

    oaep_label_hash
        Specify the Hash Algorithm to use for the rsa-oaep label as
        specified by oaep_params.

        The default is sha1. Supported algorithms are:

        *   sha1 <http://www.w3.org/2000/09/xmldsig#sha1>

        *   sha224 <http://www.w3.org/2001/04/xmldsig-more#sha224>

        *   sha256 <http://www.w3.org/2001/04/xmlenc#sha256>

        *   sha384 <http://www.w3.org/2001/04/xmldsig-more#sha384>

        *   sha512 <http://www.w3.org/2001/04/xmlenc#sha512>

    key_name
        Specify a key name to add to the KeyName element. If it is not
        specified then no KeyName element is added to the KeyInfo

  decrypt( ... )
    Main decryption function.

    Arguments:

    xml XML containing the encrypted data.

  encrypt( ... )
    Main encryption function.

    Arguments:

    xml XML containing the plaintext data.
