<p> The XML Security Library allows application to load multiple
"xmlsec-<crypto> libraries. To prevent symbol conflicts,
all "xmlsec-mycrypto" library names MUST start with "xmlSecMyCrypto".
However, in some applications (for example, the xmlsec command line
utility) that can use any crypto library, would prefer to
use a generic function names where possible.
The "include/xmlsec/crypto.h" and "include/xmlsec/mycrypto/symbols.h"
include files do the magic by mapping "xmlSecMyCrypto*" to
"xmlSecCrypto*" names using "XMLSEC_CRYPTO_*" defines.
</p>
<p> In order to build xmlsec command line utility, the
"xmlsec-<crypto>" library must implement several functions.
The stubs for all these functions are provided in the "skeleton"
we've created. While these functions are not required to be
implemented by "xmlsec-<crypto>" library, you should consider
doing so (if possible) to simplify testing (thru xmlsec command line
utility) and application development.
</p>
<p> In adition to xmlSecCryptoApp* functions, the xmlsec-<crypto>
library MUST implement following xmlSecCrypto* functions:

<tbody>
<tr>
<td>xmlSecCryptoInit()</td>
<td>Initializes xmlsec-<crypto> library: registers cryptographic
transforms implemented by the library, keys, etc.
Please note, that the application might want to intialize
the cryprographic library by itself. The default cryprographic
library initialization (for example, used by xmlsec utility)
is implemented in xmlSecCryptoAppInit() function.
