Member Function Documentation

◆ AddDataRange()

void svl::crypto::Signing::AddDataRange	(	const void *	pData,
		sal_Int32	size
	)

inline

Add a range to sign.

Note: for efficiency this takes a naked pointer, which must remain valid until this object is discarded.

Definition at line 60 of file cryptosign.hxx.

References pData, and size.

◆ SetSignPassword()

void svl::crypto::Signing::SetSignPassword ( const OUString & password )

inline

Definition at line 66 of file cryptosign.hxx.

◆ SetSignTSA()

void svl::crypto::Signing::SetSignTSA ( const OUString & tsa )

inline

Definition at line 65 of file cryptosign.hxx.

◆ Sign()

bool svl::crypto::Signing::Sign ( OStringBuffer & rCMSHexBuffer )

Signs one or more data blocks (as a single, contiguous, array).

Returns the signature (in PKCS#7 format) as string (hex).

◆ Verify() [1/2]

bool svl::crypto::Signing::Verify	(	const std::vector< unsigned char > &	aData,
		const bool	bNonDetached,
		const std::vector< unsigned char > &	aSignature,
		SignatureInformation &	rInformation
	)

static

Verify and get Signature Information given a byte array.

		const bool	bNonDetached,
		const std::vector< unsigned char > &	aSignature,
