Detailed Description

HCRYPTPROV wrapper class.

Constructor & Destructor Documentation

◆ ~crypt_prov()

virtual winstd::crypt_prov::~crypt_prov ( )

inlinevirtual

Releases the cryptographic context.

See also: CryptReleaseContext function

Member Function Documentation

◆ create()

bool winstd::crypt_prov::create	(	1 LPCTSTR	szContainer,
		1 LPCTSTR	szProvider,
		1 DWORD	dwProvType,
		1 DWORD	dwFlags = `0`
	)

inlinenoexcept

Acquires the cryptographic context.

Returns

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