## Detailed Description

XMLObject representing XML Digital Signature, version 20020212, Signature element.

The default signature settings include Exclusive c14n w/o comments, SHA-1 digests, and RSA-SHA1 signing.

## Constructor & Destructor Documentation

xmlsignature::Signature::Signature | ( |  | ) |
| protected

Default constructor.

## Member Function Documentation

virtual Signature* xmlsignature::Signature::cloneSignature | ( |  | ) | const
| pure virtual

Type-safe clone operation.

Returns
  copy of object

static unsigned int xmlsignature::Signature::createRawSignature | ( | XSECCryptoKey * | key,
|  | const XMLCh * | sigAlgorithm,
|  | const char * | in,
|  | unsigned int | in_len,
|  | char * | out,
|  | unsigned int | out_len
| ) |  |
| static

Sign the input data and return a base64-encoded signature.

The signature value MUST NOT contain any embedded linefeeds.

Allows specialized applications to create raw signatures over any input using the same cryptography layer as XML Signatures use.

Parameters

  key | key to sign with, will NOT be freed
  sigAlgorithm | XML signature algorithm identifier
  in | input data
  in_len | size of input data in bytes
  out | output buffer
  out_len | size of output buffer in bytes

Returns
  size in bytes of base64-encoded signature

virtual const XMLCh* xmlsignature::Signature::getCanonicalizationMethod | ( |  | ) | const
| pure virtual

Gets the canonicalization method for the ds:SignedInfo element.

Returns
  the canonicalization method

virtual ContentReference* xmlsignature::Signature::getContentReference | ( |  | ) | const
| pure virtual

Gets the ContentReference object associated with the Signature.

This is NOT provided for access to the data associated with an unmarshalled signature. It is used only in the creation of signatures. Access to data for validation purposes is provided through the native DSIGSignature object.

Returns
  pointer to a ContentReference object, or nullptr

virtual KeyInfo* xmlsignature::Signature::getKeyInfo | ( |  | ) | const
| pure virtual

Gets the KeyInfo object associated with the Signature.

This is NOT provided for access to the data associated with an unmarshalled signature. It is used only in the creation of signatures. Access to data for validation purposes is provided through the native DSIGSignature object.

Returns
  pointer to a KeyInfo object, or nullptr

virtual const XMLCh* xmlsignature::Signature::getSignatureAlgorithm | ( |  | ) | const
| pure virtual

Gets the signing algorithm for the signature.

Returns
  the signature algorithm, or nullptr if indeterminate

virtual DSIGSignature* xmlsignature::Signature::getXMLSignature | ( |  | ) | const
| pure virtual

Gets the native Apache signature object, if present.

Returns
  the native Apache signature interface

virtual void xmlsignature::Signature::setCanonicalizationMethod | ( | const XMLCh * | c14n | ) |
| pure virtual

Sets the canonicalization method for the ds:SignedInfo element.

Parameters

  c14n | the canonicalization method

virtual void xmlsignature::Signature::setContentReference | ( | ContentReference * | reference | ) |
| pure virtual

Sets the ContentReference object to the Signature to be applied when the signature is created.

Parameters

  reference | the reference to attach, or nullptr

virtual void xmlsignature::Signature::setKeyInfo | ( | KeyInfo * | keyInfo | ) |
| pure virtual

Sets a KeyInfo object to embed in the Signature.

Parameters

  keyInfo | pointer to a KeyInfo object, or nullptr

virtual void xmlsignature::Signature::setSignatureAlgorithm | ( | const XMLCh * | sm | ) |
| pure virtual

Sets the signing algorithm for the signature.

Parameters

  sm | the signature algorithm

virtual void xmlsignature::Signature::setSigningKey | ( | XSECCryptoKey * | signingKey | ) |
| pure virtual

Sets the signing key used to create the signature.

Parameters

  signingKey | the secret/private key used to create the signature

virtual void xmlsignature::Signature::sign | ( | const xmltooling::Credential * | credential = `0` | ) |
| pure virtual

Compute and append the signature based on the assigned ContentReference, KeyInfo, and signing key.

Parameters

  credential | optional source of signing key and KeyInfo

static bool xmlsignature::Signature::verifyRawSignature | ( | XSECCryptoKey * | key,
|  | const XMLCh * | sigAlgorithm,
|  | const char * | signature,
|  | const char * | in,
|  | unsigned int | in_len
| ) |  |
| static

Verifies a base-64 encoded signature over the input data.

Allows specialized applications to verify raw signatures over any input using the same cryptography layer as XML Signatures use.

Parameters

  key | key to verify with, will NOT be freed
  sigAlgorithm | XML signature algorithm identifier
  signature | base64-encoded signature value
  in | input data
  in_len | size of input data in bytes
