getType
public SymmetricKey.Type getType()

getOwningToken

getStrength
public int getStrength()
- Returns key strength, measured as the number of bits of secret material.
NOTE: Due to a bug in the security library (333440), this
may return a wrong answer for PBE keys that have embedded parity
(like DES). A DES key is 56 bits of information plus
8 bits of parity, so it takes up 64 bits. For a normal DES key,
this method will correctly return 56, but for a PBE-generated DES key,
the security library bug causes it to return 64.
