Method Detail

generateKey

public static void generateKey(java.lang.String algorithm,
                               int strength,
                               byte[] seed,
                               java.lang.String file,
                               java.lang.StringBuffer passphrase)
                        throws KeystoreException

Generates a secret (= symmetric) key object and store it in a file

Parameters:

algorithm - encryption algorithm (e.g. "Rijndael")

strength - the keysize in bits (e.g. 128)

seed - seed for SecureRandom (optional)

file - the file(name) to store the key

passphrase - the passphrase for the keystore

Throws:

KeystoreException - for all errors

loadKey

public static java.security.Key loadKey(java.lang.String algorithm,
                                        java.lang.String file,
                                        java.lang.StringBuffer passphrase)
                                 throws KeystoreException

Load the secret (= symmetric) key object from the keystore

Parameters:

algorithm - String encryption algorithm (e.g. "Rijndael")

file - String the keystore file(name)

passphrase - StringBuffer the passphrase for the keystore

Returns:

Keystore secretkey object

Throws:

KeystoreException - for all errors
