SignedInfo

public SignedInfo(EbicsUser user,
 byte[] digest)

Constructs a new SignedInfo element

Parameters:

digest - the digest value

Method Details

build

public void build()
           throws EbicsException

Description copied from interface: EbicsElement

Builds the EbicsElement XML fragment

Throws:

EbicsException

getDigest

public byte[] getDigest()

Returns the digest value.

Returns:

the digest value.

getSignatureType

public SignatureType getSignatureType()

Returns the signed info element as an XmlObject

Returns:

he signed info element

sign

public byte[] sign(byte[] toSign)
            throws EbicsException

Canonizes and signs a given input with the authentication private key. of the EBICS user.

The given input to be signed is first Canonized using the http://www.w3.org/TR/2001/REC-xml-c14n-20010315 algorithm.

The element to be canonized is only the SignedInfo element that should be contained in the request to be signed. Otherwise, a TransformationException is thrown.

The namespace of the SignedInfo element should be named ds as specified in the EBICS specification for common namespaces nomination.

The signature is ensured using the user X002 private key. This step is done in authenticate.

Parameters:

toSign - the input to sign

Returns:

the signed input

Throws:

EbicsException - signature fails.

toByteArray

public byte[] toByteArray()

Description copied from interface: EbicsRootElement

Converts the EbicsElement to a byte array

Specified by:

Overrides:

toByteArray in class DefaultEbicsRootElement

Returns:

the equivalent byte array of this EbicsElement

getName

public String getName()

Description copied from interface: EbicsElement

Returns the name of this EbicsElement

Returns:

the name of the element
