Fix creating keys with Passphrase.emptyPassphrase()

Browse source 
Previously the code supplied `null` to BouncyCastle's
encryptor/decryptor builder's build method and that caused
NullPointerException to be thrown.

The fix checks if the passphrase is empty and omits the BouncyCastle
builder in that case.

Fixes #16.
