Destructor (prevents use of direct delete).

Member Function Documentation

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

Authenticate a client.

Parameters
credCredentials supplied by the client.
parmsPlace where the address of additional authentication data is to be placed for another autrhentication handshake.
einfoThe 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 *  inbuff,
int  inlen,
XrdSecBuffer **  outbuff 
)
inlinevirtual

Decrypt data in inbuff using the session key.

Parameters
inbuffbuffer holding data to be decrypted.
inlenlength of the data.
outbuffplace 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 *  inbuff,
int  inlen,
XrdSecBuffer **  outbuff 
)
inlinevirtual

Encrypt data in inbuff using the session key.

Parameters
inbuffbuffer holding data to be encrypted.
inlenlength of the data.
outbuffplace 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
parmPointer to the information returned by the server either in the initial login response or the authmore response.
einfoThe 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 *  buff = 0,
int  size = 0 
)
inlinevirtual

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

Parameters
buffbuffer to hold the key, and may be null.
sizesize 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 *  buff,
int  size 
)
inlinevirtual

Set the current encryption key

Parameters
buffbuffer that holds the key.
sizesize 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 *  inbuff,
int  inlen,
XrdSecBuffer **  outbuff 
)
inlinevirtual

Sign data in inbuff using the session key.

Parameters
inbuffbuffer holding data to be signed.
inlenlength of the data.
outbuffplace 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 *  inbuff,
int  inlen,
const char *  sigbuff,
int  siglen 
)
inlinevirtual

Verify a signature using the session key.

Parameters
inbuffbuffer holding data to be verified.
inlenlength of the data.
sigbuffpointer to the signature data.
siglenlength 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.
