Member Function Documentation

createFromDER()

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

static

Creates an RSA private key object from DER data.

Parameters

der	DER data.
derLengthBytes	DER data length in bytes.

Returns

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

createFromPEM()

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

static

Creates an RSA private 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 private key object or NULL on memory allocation error or invalid PEM data.

decrypt()

unsigned char* Superpowered::RSAPrivateKey::decrypt	(	void *	encrypted,
		unsigned int *	decryptedSizeBytes,
		bool	OAEP_PSS_V21
	)

RSA decryption with private key.

Parameters

encrypted	Encrypted input data.
decryptedSizeBytes	The length of the decrypted (output) data in bytes.
OAEP_PSS_V21	True for OAEP PSS v2.1, false for PKCS1 v1.5.

Returns

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

isPair()

bool Superpowered::RSAPrivateKey::isPair

(

RSAPublicKey *

publicKey

)

Checks if a public key is the pair of this private key.

Parameters

publicKey

The public key object.

Returns

True if the public key is the pair of this private key, false otherwise.

sign()

unsigned char* Superpowered::RSAPrivateKey::sign	(	hashType	alg,
		unsigned int	inputLengthBytes,
		void *	input,
		bool	OAEP_PSS_V21
	)

Creates an RSA signature.

Parameters

alg	The hashing algorithm to use.
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

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

signHash()

unsigned char* Superpowered::RSAPrivateKey::signHash	(	hashType	alg,
		unsigned int	hashLengthBytes,
		const unsigned char *	hash,
		bool	OAEP_PSS_V21
	)

Creates an RSA signature.

Parameters

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

Returns

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