    Neither is the module that was posted. What's your point?
      Let me explain a little background. In an embedded device exists perl as a means for reliable memory management and possibility to fix bugs remotely. As a "security" (against reverse engineering) the policy is only to run from internal mem. There are three blocks (1536 bytes) available that I try to use for encrypting a database (tied hash) on external mem as a more real means of security. SHA is available because "auth the updates". Blowfish alone is more than 3 blocks.

      Sorry about the missing blanks, but I forgot to "ungolf" this.

        Doesn't change the fact that SHA doesn't provide encryption. Any use of it is pure obfuscation, not encryption. I'm sure there are encryption algorithms designed for use in memory-tight systems.
