Member Function Documentation

virtual int XrdSecProtocol::Authenticate	(	XrdSecCredentials *	cred,
		XrdSecParameters **	parms,
		XrdOucErrInfo *	einfo = 0
	)			[pure virtual]

Authenticate a client.

Parameters:

	cred	Credentials supplied by the client.
	parms	Place where the address of additional authentication data is to be placed for another autrhentication handshake.
	einfo	The error information object where error messages should be placed. The messages are returned to the client. Should einfo be null, messages should be written to stderr.

Returns:

> 0 -> parms present (more authentication needed) = 0 -> Entity present (authentication suceeded) < 0 -> einfo present (error has occured)

virtual int XrdSecProtocol::Decrypt	(	const char *	,
		int	,
		XrdSecBuffer **
	)			[inline, virtual]

Decrypt data in inbuff using the session key.

Parameters:

	inbuff	buffer holding data to be decrypted.
	inlen	length of the data.
	outbuff	place where a pointer to the decrypted data is placed.

Returns:

< 0 Failed,the return value is -errno (see Encrypt). = 0 Success, outbuff contains a pointer to the decrypted data. The caller is responsible for deleting the returned object.

virtual void XrdSecProtocol::Delete

(

)

[pure virtual]

Delete the protocol object. DO NOT use C++ delete() on this object.

virtual int XrdSecProtocol::Encrypt	(	const char *	,
		int	,
		XrdSecBuffer **
	)			[inline, virtual]

Encrypt data in inbuff using the session key.

Parameters:

	inbuff	buffer holding data to be encrypted.
	inlen	length of the data.
	outbuff	place where a pointer to the encrypted data is placed.

Returns:

< 0 Failed, the return value is -errno of the reason. Typically, -EINVAL - one or more arguments are invalid. -NOTSUP - encryption not supported by the protocol -ENOENT - Context not innitialized = 0 Success, outbuff contains a pointer to the encrypted data. The caller is responsible for deleting the returned object.

virtual XrdSecCredentials* XrdSecProtocol::getCredentials	(	XrdSecParameters *	parm = 0,
		XrdOucErrInfo *	einfo = 0
	)			[pure virtual]

Generate client credentials to be used in the authentication process.

Parameters:

	parm	Pointer to the information returned by the server either in the initial login response or the authmore response.
	einfo	The error information object where error messages should be placed. The messages are returned to the client. Should einfo be null, messages should be written to stderr.

Returns:

Success: Pointer to credentials to sent to the server. The caller is responsible for deleting the object. Failure: Null pointer with einfo, if supplied, containing the reason for the failure.

virtual int XrdSecProtocol::getKey	(	char *	= 0,
		int	= 0
	)			[inline, virtual]

Get the current encryption key (i.e. session key)

Parameters:

	buff	buffer to hold the key, and may be null.
	size	size of the buffer.

Returns:

< 0 Failed, returned value if -errno (see Encrypt) >= 0 The size of the encyption key. The supplied buffer of length size hold the key. If the buffer address is supplied, the key is placed in the buffer.

virtual int XrdSecProtocol::setKey	(	char *	,
		int
	)			[inline, virtual]

Set the current encryption key

Parameters:

	buff	buffer that holds the key.
	size	size of the key.

Returns:

: < 0 Failed, returned value if -errno (see Encrypt) = 0 The new key has been set.

virtual int XrdSecProtocol::Sign	(	const char *	,
		int	,
		XrdSecBuffer **
	)			[inline, virtual]

Sign data in inbuff using the session key.

Parameters:

	inbuff	buffer holding data to be signed.
	inlen	length of the data.
	outbuff	place where a pointer to the signature is placed.

Returns:

< 0 Failed,the return value is -errno (see Encrypt). = 0 Success, outbuff contains a pointer to the signature. The caller is responsible for deleting the returned object.

virtual int XrdSecProtocol::Verify	(	const char *	,
		int	,
		const char *	,
		int
	)			[inline, virtual]

Verify a signature using the session key.

Parameters:

	inbuff	buffer holding data to be verified.
	inlen	length of the data.
	sigbuff	pointer to the signature data.
	siglen	length of the signature data.

Returns:

< 0 Failed,the return value is -errno (see Encrypt). = 0 Success, signature is correct. > 0 Failed to verify, signature does not match inbuff data.
