Algorithm

public Algorithm(java.lang.String algorithm0,
                 int keySize0)
          throws SMIMEException

Object construction with the given name of algorithm and key size in bits. This constructor performs checking of the imported parameters of the algorithm and defines specific names for later use in Chiper class.

Parameters:

algorithm0 - name of the one of the following algorithms: "DES", "DES_EDE3_CBC" and "RC2_CBC".

keySize0 - key size in bits.

Throws:

SMIMEException - in case of invalid algorithm names, or in case of wrong key sizes in bits.

Method Detail

getAlgorithmName

public java.lang.String getAlgorithmName()

Returns algorithm name used in the symmetric encryption.

Returns:

Name of the chosen algorithm for symmetric encryption.

getKeySize

public int getKeySize()

Returns key size in bits which is used in the symmetric algorithm.

Returns:

Key size in bits for the algorithm used in the symmetric encryption.
