Method Detail |
public static Key buildKey(byte keyType, short keyLength, boolean keyEncryption) throws CryptoException
Signature
and Cipher
.
Note that the object returned must be cast to their appropriate key type interface.
keyType
- the type of key to be generated. Valid codes listed in TYPE.. constants.keyLength
- the key size in bits. The valid key bit lengths are key type dependent. See above.keyEncryption
- if true
this boolean requests a key implementation
which implements the javacardx.crypto.KeyEncryption
interface.
The key implementation returned may implement the javacardx.crypto.KeyEncryption
interface even when this parameter is false
.
CryptoException
- with the following reason codes:CryptoException.NO_SUCH_ALGORITHM
if the requested algorithm
associated with the specified type, size of key and key encryption interface is not supported.
