The XMLEncrypt class is used to encrypt and decrypt XML.

Syntax

ipworksencrypt.xmlencrypt()

Remarks

The XMLEncrypt class provides a simple API for encrypting and decrypting XML. The Encrypt method will encrypt the XML document, or a specific element. Multiple elements may be encrypted at one time by setting EncryptedDataDetails. The Decrypt method will decrypt the XML document.

The class supports encrypting and decrypting with a shared SymmetricKey, and also using asymmetric encryption to encrypt the SymmetricKey (session key) via the RecipientCert and Certificate properties.

Encrypt

To begin first specify a XML document by setting InputFile, or InputXML.

The EncryptedDataDetails property specify the XML element to encrypt. By default the entire XML document is encrypted.

The SymmetricKey property specifies the key which will be used to encrypt the data.

If the RecipientCert property is set, then the SymmetricKey will be encrypted and included in the encrypted data. This allows for the recipient to decrypt the key, with their certificate. Encrypting the symmetric key is also referred to as using a session key. The benefit of using certificate to encrypt and decrypt a session key (SymmetricKey) is that knowledge of the key value is not needed ahead of time to process the encrypted data. Note that if specified, RecipientCert MUST have a RSA key, not a DSA key.

If the RecipientCert property is not set, then the recipient must know the value of SymmetricKey before decrypting the XML. The KeyName setting may be set to provide a key identifier to the recipient.

Optionally set EncryptingAlgorithm, and then call Encrypt to encrypt the XML.

The following properties are applicable when calling this method:

Input and Output Properties

The class will determine the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

When a valid source is found, the search stops. The order in which the output properties are checked is as follows:
  • OutputFile
  • OutputXML: The output data is written to this property if no other destination is specified.

Decrypt

To begin first specify a XML document by setting InputFile, or InputXML.

The SymmetricKey property specifies the key used to decrypt the data. This may be set before calling Decrypt or inside the EncryptedDataInfo event. The EncryptedDataInfo event fires once for each encrypted element when Decrypt is called.

If the data was encrypted using an session key, set the Certificate property to the certificate with private key before calling Decrypt. The certificate will be used to decrypt the encrypted session key. In this case the SymmetricKey property is ignored.

The following properties are applicable when calling this method:

    Constructors

    public Certificate();

    Creates a instance whose properties can be set. This is useful for use with when generating new certificates. 

    public Certificate(String certificateFile);

    Opens CertificateFile and reads out the contents as an X.509 public key. 

    public Certificate(byte[] encoded);

    Parses Encoded as an X.509 public key. 

    public Certificate(int storeType, String store, String storePassword, String subject);

    StoreType identifies the type of certificate store to use. See for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store.

    After the store has been successfully opened, the class will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X.509 certificate's subject Distinguished Name (DN). The Subject parameter can also take an MD5, SHA-1, or SHA-256 thumbprint of the certificate to load in a "Thumbprint=value" format. 

    public Certificate(int storeType, String store, String storePassword, String subject, String configurationString);

    StoreType identifies the type of certificate store to use. See for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store.

    ConfigurationString is a newline-separated list of name-value pairs that may be used to modify the default behavior. Possible values include "PersistPFXKey", which shows whether or not the PFX key is persisted after performing operations with the private key. This correlates to the PKCS12_NO_PERSIST_KEY CryptoAPI option. The default value is True (the key is persisted). "Thumbprint" - an MD5, SHA-1, or SHA-256 thumbprint of the certificate to load. When specified, this value is used to select the certificate in the store. This is applicable to the cstUser , cstMachine , cstPublicKeyFile , and cstPFXFile store types. "UseInternalSecurityAPI" shows whether the platform (default) or the internal security API is used when performing certificate-related operations.

    After the store has been successfully opened, the class will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X.509 certificate's subject Distinguished Name (DN). The Subject parameter can also take an MD5, SHA-1, or SHA-256 thumbprint of the certificate to load in a "Thumbprint=value" format. 

    public Certificate(int storeType, String store, String storePassword, byte[] encoded);

    StoreType identifies the type of certificate store to use. See for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store.

    After the store has been successfully opened, the class will load Encoded as an X.509 certificate and search the opened store for a corresponding private key. 

    public Certificate(int storeType, byte[] store, String storePassword, String subject);

    StoreType identifies the type of certificate store to use. See for descriptions of the different certificate stores. Store is a byte array containing the certificate data. StorePassword is the password used to protect the store.

    After the store has been successfully opened, the class will attempt to find the certificate identified by Subject .

    public XMLEncryptedDataDetail(String id, String XMLElement, int scope, String MIMEType);

    Config Settings (class ipworksencrypt.xmlencrypt)

    The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

    XMLEnc Config Settings

    DecryptWithCryptoAPI:   Whether to use the Crypto API for decrypt operations.

    This setting determines whether to use the Microsoft Crypto API to decrypt. This is helpful in cases where the certificate is present in the Windows Certificate Store but the private key is not marked as exportable. For instance when using a USB security key. The default value is False.

    Note: This functionality is only available on Windows.

    EncryptedKeyXPath:   The XPath of the EncryptedKey element.

    This setting specifies the XPath where the EncryptedKey element will be written. In most cases this does not need to be changed. By default it is included in the EncryptedData element.

    KeyName:   The name of the key used to encrypt the XML.

    This setting optionally holds the key name which may be useful to the recipient to help identify the key used to encrypt the data. This may be set before calling Encrypt. When calling Decrypt this may be queried inside the EncryptedDataInfo event.

    Note that this value is only informative, it does not affect processing.

    LogLevel:   Specifies the level of detail that is logged.

    This setting controls the level of detail that is logged through the Status event. Possible values are:

    0 (None)No events are logged.
    1 (Info - default)Informational events are logged.
    2 (Verbose)Detailed data is logged.
    3 (Debug)Debug data is logged.
    OAEPMGF1HashAlgorithm:   The MGF1 hash algorithm used with OAEP.

    This configuration setting specifies the MGF1 hash algorithm used when UseOAEP is set to True. The default value is SHA256. Possible values are as follows:

    • "SHA1"
    • "SHA224"
    • "SHA256" (default)
    • "SHA384"
    • "SHA512"
    • "RIPEMD160"
    • "MD2"
    • "MD5"
    • "MD5SHA1"

    Note: This setting is not applicable when UseFIPSCompliantAPI is set to true or when the private key of the signing certificate is not exportable since the underlying system implementation does not support separate OAEPRSAHashAlgorithm and OAEPMGF1HashAlgorithm values. In this case the OAEPRSAHashAlgorithm is also used for MGF1.

    OAEPParams:   The hex encoded OAEP parameters.

    This configuration setting optionally specifies Optimal Asymmetric Encryption Padding (OAEP) parameters to be used when UseOAEP is set to True. The specified value should be hex encoded.

    OAEPRSAHashAlgorithm:   The RSA hash algorithm used with OAEP.

    This configuration setting specifies that RSA hash algorithm used when UseOAEP is set to True. The default value is SHA256. Possible values are as follows:

    • "SHA1"
    • "SHA224"
    • "SHA256" (default)
    • "SHA384"
    • "SHA512"
    • "RIPEMD160"
    • "MD2"
    • "MD5"
    • "MD5SHA1"
    The RSA hash algorithm used when encrypting a key.

    When encryption is enabled, this algorithm specifies the RSA hash algorithm used for the encryption key. This may differ from the hash algorithm used to sign the message content. Possible values are:

    • "SHA1" (default)
    • "SHA224"
    • "SHA256"
    • "SHA384"
    • "SHA512"
    OAEPRSAHashAlgorithm:   The RSA hash algorithm used with OAEP.

    This configuration setting specifies that RSA hash algorithm used when UseOAEP is set to True. The default value is SHA256. Possible values are as follows:

    • "SHA1"
    • "SHA224"
    • "SHA256" (default)
    • "SHA384"
    • "SHA512"
    • "RIPEMD160"
    • "MD2"
    • "MD5"
    • "MD5SHA1"
    The RSA hash algorithm used when encrypting a key.

    When encryption is enabled, this algorithm specifies the RSA hash algorithm used for the encryption key. This may differ from the hash algorithm used to sign the message content. Possible values are:

    • "SHA1" (default)
    • "SHA224"
    • "SHA256"
    • "SHA384"
    • "SHA512"
    ReadFromProgressEvent:   Whether to read input data from inside the progress event.

    When set to True this setting allows input data to be specified from within the Progress event. The class will repeatedly fire the Progress event to ask for data. Inside the event set InputXML when the Operation parameter of the event is 1 (Read). When all data has been provided set the IsEOF parameter of the event to True. This allows input data to be chunked and provided piece by piece. The default value is False.

    WriteToProgressEvent:   Whether to write output data so it is accessible from inside the progress event.

    When set to True this setting allows output data to be obtained from within the Progress event. The class will repeatedly fire the Progress event to provide output data. Inside the event check OutputXML when the Operation parameter of the event is 2 (Write). The IsEOF parameter should be checked inside the event to determine when all output data has been provided. This allows output data to be chunked and obtained piece by piece. The default value is False.

    Base Config Settings

    BuildInfo:   Information about the product's build.

    When queried, this setting will return a string containing information about the product's build.

    CodePage:   The system code page used for Unicode to Multibyte translations.

    UseInternalSecurityAPI:   Whether or not to use the system security libraries or an internal implementation.

    When set to false, the class will use the system security libraries by default to perform cryptographic functions where applicable.

    Setting this configuration setting to true tells the class to use the internal implementation instead of using the system security libraries.

    This setting is set to false by default on all platforms.
