Creates a key definition name and value to be used for encrypting
    and decrypting files. The key is a string that represents the
    name under which its value is encrypted and stored in the key
    storage table; a logical name table. A DES key is created in the
    PROCESS logical name table by default unless the /AES qualifier
    is specified. Note that AES requires longer key-length values
    than the 8-byte DES keys. AES requires a minimum of 16, 24,
    or 32 bytes depending on the algorithm/key size specified for
    encryption or decryption.
