XLATEASM(8) Legato NetWorker 3.0 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 Thus, we do not
publish what this algorithm is.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.
