Detailed Description

HCRYPTHASH wrapper class.

Constructor & Destructor Documentation

◆ ~crypt_hash()

virtual winstd::crypt_hash::~crypt_hash ( )

inlinevirtual

Destroys the hash context.

Member Function Documentation

◆ create()

bool winstd::crypt_hash::create	(	1 HCRYPTPROV	hProv,
		1 ALG_ID	Algid,
		1 HCRYPTKEY	hKey = `NULL`,

	)

inlinenoexcept

Creates the hash context.

Returns

true when creation succeeds;
false when creation fails. For extended error information, call GetLastError().
