Detailed Description

Interface class for DSA keys.

The library uses classes derived from this to process DSA keys.

Public Member Functions
Constructors and Destructors
	XSECCryptoKeyDSA ()
virtual	~XSECCryptoKeyDSA ()
Key Interface methods
virtual XSECCryptoKey::KeyType	getKeyType ()
	Return the type of this key.
virtual XSECCryptoKey *	clone ()=0
	Replicate key.
Mandatory DSA interface methods
These classes are required by the library.
virtual bool	verifyBase64Signature (unsigned char *hashBuf, unsigned int hashLen, char *base64Signature, unsigned int sigLen)=0
	Verify a signature.
virtual unsigned int	signBase64Signature (unsigned char *hashBuf, unsigned int hashLen, char *base64SignatureBuf, unsigned int base64SignatureBufLen)=0
	Create a signature.
Optional Interface methods
These functions do not necessarily have to be implmented. They are used by XSECKeyInfoResolverDefault to try to create a key from KeyInfo elements without knowing anything else. If an interface class does not implement these functions, a simple stub that does nothing should be used.
virtual void	loadPBase64BigNums (const char *b64, unsigned int len)=0
	Load P.
virtual void	loadQBase64BigNums (const char *b64, unsigned int len)=0
	Load Q.
virtual void	loadGBase64BigNums (const char *b64, unsigned int len)=0
	Load G.
virtual void	loadYBase64BigNums (const char *b64, unsigned int len)=0
	Load Y.
virtual void	loadJBase64BigNums (const char *b64, unsigned int len)=0
	Load J.

Member Function Documentation

virtual XSECCryptoKey* XSECCryptoKeyDSA::clone (   )  [pure virtual]

Replicate key. Implements XSECCryptoKey. Implemented in OpenSSLCryptoKeyDSA, and WinCAPICryptoKeyDSA.

virtual XSECCryptoKey::KeyType XSECCryptoKeyDSA::getKeyType (   )  [inline, virtual]

Return the type of this key. For DSA keys, this allows people to determine whether this is a public key, private key or a key pair Reimplemented from XSECCryptoKey. Reimplemented in OpenSSLCryptoKeyDSA, and WinCAPICryptoKeyDSA.

virtual void XSECCryptoKeyDSA::loadGBase64BigNums (  const char *  b64, unsigned int  len )  [pure virtual]

Load G. Parameters: b64  Base64 encoded parameter - read from XML document len  Length of the encoded string Implemented in OpenSSLCryptoKeyDSA, and WinCAPICryptoKeyDSA.

virtual void XSECCryptoKeyDSA::loadJBase64BigNums (  const char *  b64, unsigned int  len )  [pure virtual]

Load J. Parameters: b64  Base64 encoded parameter - read from XML document len  Length of the encoded string Implemented in OpenSSLCryptoKeyDSA, and WinCAPICryptoKeyDSA.

virtual void XSECCryptoKeyDSA::loadPBase64BigNums (  const char *  b64, unsigned int  len )  [pure virtual]

Load P. Parameters: b64  Base64 encoded parameter - read from XML document len  Length of the encoded string Implemented in OpenSSLCryptoKeyDSA, and WinCAPICryptoKeyDSA.

virtual void XSECCryptoKeyDSA::loadQBase64BigNums (  const char *  b64, unsigned int  len )  [pure virtual]

Load Q. Parameters: b64  Base64 encoded parameter - read from XML document len  Length of the encoded string Implemented in OpenSSLCryptoKeyDSA, and WinCAPICryptoKeyDSA.

virtual void XSECCryptoKeyDSA::loadYBase64BigNums (  const char *  b64, unsigned int  len )  [pure virtual]

Load Y. Parameters: b64  Base64 encoded parameter - read from XML document len  Length of the encoded string Implemented in OpenSSLCryptoKeyDSA, and WinCAPICryptoKeyDSA.

virtual unsigned int XSECCryptoKeyDSA::signBase64Signature (  unsigned char *  hashBuf, unsigned int  hashLen, char *  base64SignatureBuf, unsigned int  base64SignatureBufLen )  [pure virtual]

Create a signature. The library will call this function to create a signature from a pre-calculated digest. The output signature is required to be Base64 encoded such that it can be placed directly into the XML document Parameters: hashBuf  Buffer containing the pre-calculated (binary) digest hashLen  Number of bytes of hash in the hashBuf base64SignatureBuf  Buffer to place the base64 encoded result in. base64SignatureBufLen  Implementations need to ensure they do not write more bytes than this into the buffer Implemented in OpenSSLCryptoKeyDSA, and WinCAPICryptoKeyDSA.

virtual bool XSECCryptoKeyDSA::verifyBase64Signature (  unsigned char *  hashBuf, unsigned int  hashLen, char *  base64Signature, unsigned int  sigLen )  [pure virtual]

Verify a signature. The library will call this function to validate a signature Parameters: hashBuf  Buffer containing the pre-calculated (binary) digest hashLen  Length of the data in the digest buffer base64Signature  Buffer containing the Base64 encoded signature sigLen  Length of the data in the signature buffer Returns: true if the signature was valid, false otherwise Implemented in OpenSSLCryptoKeyDSA, and WinCAPICryptoKeyDSA.
