A method and apparatus is provided for transferring encrypted files from a source computer to one or more target computers. An export program is provided in the source computer and an import program is provided in the target computer. The export program decrypts the encrypted file and tags the export operation with an export counter value. The clear text file is then encrypted with an encryption operation utilizing a key which is unique to a transfer memory media, such as diskette serial number. The memory media is carried to a target computer which utilizes the import file to decrypt the encrypted file.
