dl — Dynamic crypto-engine library loading support.

Description

Dynamic crypto-engine library loading support.

Functions

xmlSecCryptoDLFunctionsRegisterKeyDataAndTransforms ()

int
xmlSecCryptoDLFunctionsRegisterKeyDataAndTransforms
                               (xmlSecCryptoDLFunctionsPtr functions);

Registers the key data and transforms klasses from functions table in xmlsec.

Parameters

functions

the functions table.

Returns

0 on success or a negative value if an error occurs.


xmlSecCryptoDLInit ()

int
xmlSecCryptoDLInit (void);

Initializes dynamic loading engine. This is an internal function and should not be called by application directly.

Returns

0 on success or a negative value if an error occurs.


xmlSecCryptoDLShutdown ()

int
xmlSecCryptoDLShutdown (void);

Shutdowns dynamic loading engine. This is an internal function and should not be called by application directly.

Returns

0 on success or a negative value if an error occurs.


xmlSecCryptoDLLoadLibrary ()

int
xmlSecCryptoDLLoadLibrary (const xmlChar *crypto);

Loads the xmlsec-$crypto library. This function is NOT thread safe, application MUST NOT call xmlSecCryptoDLLoadLibrary, xmlSecCryptoDLGetLibraryFunctions, and xmlSecCryptoDLUnloadLibrary functions from multiple threads.

Parameters

crypto

the desired crypto library name ("openssl", "nss", ...). If NULL then the default crypto engine will be used.

Returns

0 on success or a negative value if an error occurs.


xmlSecCryptoDLGetLibraryFunctions ()

xmlSecCryptoDLFunctionsPtr
xmlSecCryptoDLGetLibraryFunctions (const xmlChar *crypto);

Loads the xmlsec-$crypto library and gets global crypto functions/transforms/keys data/keys store table. This function is NOT thread safe, application MUST NOT call xmlSecCryptoDLLoadLibrary, xmlSecCryptoDLGetLibraryFunctions, and xmlSecCryptoDLUnloadLibrary functions from multiple threads.

Parameters

crypto

the desired crypto library name ("openssl", "nss", ...).

Returns

the table or NULL if an error occurs.


xmlSecCryptoDLUnloadLibrary ()

int
xmlSecCryptoDLUnloadLibrary (const xmlChar *crypto);

Unloads the xmlsec-$crypto library. All pointers to this library functions tables became invalid. This function is NOT thread safe, application MUST NOT call xmlSecCryptoDLLoadLibrary, xmlSecCryptoDLGetLibraryFunctions, and xmlSecCryptoDLUnloadLibrary functions from multiple threads.

Parameters

crypto

the desired crypto library name ("openssl", "nss", ...).

Returns

0 on success or a negative value if an error occurs.


xmlSecCryptoDLSetFunctions ()

int
xmlSecCryptoDLSetFunctions (xmlSecCryptoDLFunctionsPtr functions);

Sets global crypto functions/transforms/keys data/keys store table.

Parameters

functions

the new table

Returns

0 on success or a negative value if an error occurs.


xmlSecCryptoDLGetFunctions ()

xmlSecCryptoDLFunctionsPtr
xmlSecCryptoDLGetFunctions (void);

Gets global crypto functions/transforms/keys data/keys store table.

Returns

the table.
