Member Function Documentation

createFromDER()

static RSAPublicKey* Superpowered::RSAPublicKey::createFromDER ( const unsigned char *  der, unsigned int  derLengthBytes  )

static

Creates an RSA public key object from DER data.

Parameters

der	DER data.
derLengthBytes	DER data length in bytes.

Returns

The new RSA public key object or NULL on memory allocation error or invalid DER data.

createFromPEM()

static RSAPublicKey* Superpowered::RSAPublicKey::createFromPEM ( const char *  pem, unsigned int  pemLengthBytes  )

static

Creates an RSA public key object from a PEM string.

Parameters

pem	PEM string.
pemLengthBytes	PEM string length (not including the trailing zero if any).

Returns

The new RSA public key object or NULL on memory allocation error or invalid PEM data.

encrypt()

unsigned char* Superpowered::RSAPublicKey::encrypt	(	unsigned int	inputLengthBytes,
		void *	input,
		bool	OAEP_PSS_V21
	)

RSA encryption with public key.

Parameters

inputLengthBytes	The length of input in bytes.
input	Input data.
OAEP_PSS_V21	True for OAEP PSS v2.1, false for PKCS1 v1.5.

Returns

Encrypted data or NULL on error. Don't forget to free() this at a later point to prevent memory leaks!

getEncryptedOutputSizeBytes()

unsigned int Superpowered::RSAPublicKey::getEncryptedOutputSizeBytes

(

)

Returns

Returns with the encrypted output data size in bytes.

verifySignature()

bool Superpowered::RSAPublicKey::verifySignature	(	hashType	alg,
		unsigned int	inputLengthBytes,
		void *	input,
		const unsigned char *	signature,
		bool	OAEP_PSS_V21
	)

RSA signature verification.

Parameters

alg	The hashing algorithm to use.
inputLengthBytes	The length of input in bytes.
input	Input data.
signature	Signature string.
OAEP_PSS_V21	True for OAEP PSS v2.1, false for PKCS1 v1.5.

Returns

True if the signature is valid, false otherwise.

verifySignatureHash()

bool Superpowered::RSAPublicKey::verifySignatureHash	(	hashType	alg,
		unsigned int	hashLengthBytes,
		const unsigned char *	hash,
		const unsigned char *	signature,
		bool	OAEP_PSS_V21
	)

RSA signature verification.

Parameters

alg	The hashing algorithm to use.
hashLengthBytes	The length of hash in bytes.
hash	Hash data.
signature	Signature string.
OAEP_PSS_V21	True for OAEP PSS v2.1, false for PKCS1 v1.5.

Returns

True if the signature is valid, false otherwise.
