Method Detail

obtainKey

public final byte[] obtainKey(Algorithms algorithm)
                       throws CryptoException

Description copied from interface: KeyProvider

Obtain the current cryptographic key present in the storage. The storage used for the key returned must be protected by additional means such as access control against abuse of the key. The key is generated once at startup via the KeyGenerator and stays the same for the lifetime of the service (unless is physically erased in the storage system)

Specified by:

obtainKey in interface KeyProvider

Parameters:

algorithm - the standard string name of the algorithm. Currently supported algorithm are defined in Algorithms

Returns:

the related stored key

Throws:

CryptoException - If any problem occurs while obtaining the key
