XLATEASM(8)                 Legato NetWorker 4.0                 XLATEASM(8)


NAME
       xlateasm - NetWorker module for encrypting and decrypting files

SYNOPSIS
       xlateasm [ standard-asm-arguments ]

DESCRIPTION
       The xlateasm is a standard, external ASM (Application Specific Mod­
       ule) used to encrypt files prior to being saved and decrypt files
       when they are recovered.

       See uasm(8) for a general description of ASM's and the [standard-asm-
       arguments].  It is intended that xlateasm be invoked by uasm during
       save(8) or recover(8) operations.

       The xlateasm uses a simple encryption method to encrypt files prior
       to saving them.  This makes it less likely that someone eavesdropping
       on the network or someone who gains unauthorized access to a tape can
       decipher data.  Upon retrieval, files are decrypted into their origi­
       nal form.

NOTE
       The encryption method used by xlateasm is not very sophisticated and
       relies on the security of the encryption algorithm.  Thus, we do not
       publish what this algorithm is.  No encryption key is required.  How­
       ever, a hacker might well be able to figure out how to de-encrypt
       data either by examining the executable code or by brute force.
       Therefore, we do not recommend use of this method for any purpose
       other than to discourage prying or eliminate the possibility of unin­
       tentional examination of data.  More sophisticated methods can be
       easily built (for example, the Data Encryption Standard), but such
       methods have restrictions on their distribution by the U. S. govern­
       ment.
