	)			throw (NoSuchAlgorithmException) [static]

static Signature* beecrypt::security::Signature::getInstance	(	const String &	algorithm,
		const String &	provider
	)			throw (NoSuchAlgorithmException, NoSuchProviderException) [static]

Returns a Signature object that implements the requested algorithm, from the requested provider.

Parameters:

	algorithm	the standard algorithm name.
	provider	the name of the provider.

Exceptions:

	NoSuchAlgorithmException	if the requested algorithm is not available in the requested provider.
	NoSuchProviderException	if the requested provider is not available.

static Signature* beecrypt::security::Signature::getInstance

(

const String &

algorithm

)

throw (NoSuchAlgorithmException) [static]

Returns a Signature object that implements the requested algorithm.

If the default provider has an implementation of the requested algorithm that one is used; otherwise other providers are searched.

Parameters:

algorithm

the standard name of the requested algorithm.

Exceptions:

NoSuchAlgorithmException

if the requested algorithm is not available.
