Method Detail

getType

public SymmetricKey.Type getType()

Specified by:

getType in interface SymmetricKey

getOwningToken

public CryptoToken getOwningToken()

Specified by:

getOwningToken in interface SymmetricKey

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.
