getAlgorithm

public String getAlgorithm()

setAlgorithm

public void setAlgorithm(String algorithm)

Sets the encryption algorithm and resets the key size. You may change the key size after calling this method. Additionally run the initialize() method after setting algorithm and keysize.

Parameters:

algorithm - The encryption algorithm to use.

getKeySize

public int getKeySize()

setKeySize

public void setKeySize(int keySize)

Sets the key size for the encryption. This method must be called after setting the algorithm. The keysize will be reset by calling setAlgorithm() The key size must be valid for the given algorithm.

Parameters:

keySize - The size of the encryption key
