public KeyPairImpl(byte algorithm,
short keyLength)
throws CryptoException
KeyPair instance for the specified algorithm and keylength;
the encapsulated keys are uninitialized. To initialize the
KeyPair instance use the
genKeyPair() method. The encapsulated key objects are of
the specified
keyLength size and implement the appropriate
Key interface associated with the specified algorithm
(example -
RSAPublicKey interface for the public key and
RSAPrivateKey interface for the private key within an
ALG_RSA key pair).
Notes:
KeyPair object need
not support the KeyEncryption interface.
algorithm - the type of algorithm whose key pair needs to be
generated. Valid codes listed in ALG_.. constants above.
KeyPairkeyLength - the key size in bits. The valid key bit lengths are key
type dependent. See the KeyBuilder class.
CryptoException - with the following reason codes:CryptoException.NO_SUCH_ALGORITHM if the requested
algorithm associated with the specified type, size of key is not
supported.KeyBuilder,

public KeyPairImpl(PublicKey publicKey,
PrivateKey privateKey)
throws CryptoException
KeyPair object containing the specified public key and
private key. Note that this constructor only stores references to the
public and private key components in the generated
KeyPair object. It does not throw an exception if the key
parameter objects are uninitialized.
publicKey - the public key.privateKey - the private key.
CryptoException - with the following reason codes:CryptoException.ILLEGAL_VALUE if the input parameter key
objects are inconsistent with each other - i.e mismatched algorithm, size
etc. CryptoException.NO_SUCH_ALGORITHM if the algorithm
associated with the specified type, size of key is not supported. | Method Detail |

public final void genKeyPair()
throws CryptoException
KeyPair instance with new key values. The initialized public
and private key objects encapsulated in this instance will then be
suitable for use with the
Signature,
Cipher and
KeyAgreement objects. An internal secure random number
generator is used during new key pair generation. Notes:
CryptoException - with the following reason codes:CryptoException.ILLEGAL_VALUE if the exponent value
parameter in RSA or the p, q, g parameter set in DSA or the Field, A, B,
G and R parameter set in EC is invalid. APDU,
