Function Documentation

clean()

void Util::OpenSsl::clean

(

)

Cleans resources of OpenSSL.

Definition at line 119 of file openssl.cpp.

computeSha256Sum()

Sha256Sum Util::OpenSsl::computeSha256Sum	(	const unsigned char *	buffer,
		std::size_t	size )

Computes a SHA-256 sum using OpenSSL.

Definition at line 130 of file openssl.cpp.

computeTOTP()

TOTP Util::OpenSsl::computeTOTP	(	std::string_view	url,
		CppUtilities::DateTime	time )

Compute a token following the TOTP standard (RFC 6238).

Parameters

url	Specifies a URL containing the secret and parameters, e.g. "otpauth://totp/some/path?secret=ABCDABCDABCDABCD&period=30&digits=6&issuer=some_issuer".
time	Specifies the time to compute the for (UTC).

Returns

Returns the token with as many number of digits as specified in the URL.

Exceptions

Throws a CppUtilities::ConversionException if URL parameters are invalid/missing.

• Throws an Io::CryptoException if an error occurs during cryptographic computation.
