An apparatus and methods for facilitating an encryption process for use in systems employing cryptography based security, removes unnecessary data relating to encryption keys prior to storing the data after receipt of the encrypted information from a sender. Encrypted data, such as message data for multiple recipients, is analyzed to determine whether encryption related data for other recipients may be removed and/or whether a preferred encrypting process was used. In one embodiment, the apparatus and method also determines whether a non-preferred encryption process was used to encrypt encrypted data and re-encrypts the encrypted data with a different encryption process in response to detected non-preferred encryption key usage.
