> Basically, the {{CryptoCodec}} class is not a closeable, but the {{OpensslAesCtrCryptoCodec}} implementation of it contains a closeable member (the Random object). Currently it is left for {{finalize()}} to clean up, this depends on when a FGC is run, and would create problems if {{OpensslAesCtrCryptoCodec}} is used with {{OsSecureRandom}}, which could let OS run out of FDs on {{/dev/urandom}} if too many codecs created.
