Constructor & Destructor Documentation

cRsaPrivateKey::cRsaPrivateKey

(

void

)

Creates a new empty object, the key is not assigned.

Definition at line 12 of file RsaPrivateKey.cpp.

cRsaPrivateKey::cRsaPrivateKey

(

const cRsaPrivateKey &

a_Other

)

Deep-copies the key from a_Other.

Member Function Documentation

int cRsaPrivateKey::Decrypt	(	const Byte *	a_EncryptedData,
		size_t	a_EncryptedLength,
		Byte *	a_DecryptedData,
		size_t	a_DecryptedMaxLength
	)

Decrypts the data using RSAES-PKCS#1 algorithm.

Both a_EncryptedData and a_DecryptedData must be at least <KeySizeBytes> bytes large. Returns the number of bytes decrypted, or negative number for error.

Definition at line 108 of file RsaPrivateKey.cpp.

int cRsaPrivateKey::Encrypt	(	const Byte *	a_PlainData,
		size_t	a_PlainLength,
		Byte *	a_EncryptedData,
		size_t	a_EncryptedMaxLength
	)

Encrypts the data using RSAES-PKCS#1 algorithm.

Both a_EncryptedData and a_DecryptedData must be at least <KeySizeBytes> bytes large. Returns the number of bytes decrypted, or negative number for error.

Definition at line 142 of file RsaPrivateKey.cpp.

bool cRsaPrivateKey::Generate

(

unsigned

a_KeySizeBits = 1024

)

Generates a new key within this object, with the specified size in bits.

Returns true on success, false on failure.

Definition at line 42 of file RsaPrivateKey.cpp.

mbedtls_rsa_context* cRsaPrivateKey::GetInternal ( void  )

inlineprotected

Returns the internal context ptr.

Only use in mbedTLS API calls.

Definition at line 59 of file RsaPrivateKey.h.

AString cRsaPrivateKey::GetPubKeyDER

(

void

)

Returns the public key part encoded in ASN1 DER encoding.

Definition at line 58 of file RsaPrivateKey.cpp.
