Product Overview

SLiKZip is a z/OS-based compression utility designed to create and extract ZIP and GZIP archives. It operates within batch, TSO, and ISPF environments. The architecture consists of the following components: 1.

**SLIKZIP Command Processor:** This component parses the `SLIKZIP` command and its parameters, initiating the compression or extraction process. 2. **Compression/Decompression Engine:** This component implements the compression and decompression algorithms, including DEFLATE64 and AES encryption.

3. **Dataset I/O Module:** This component handles reading and writing data to and from z/OS datasets, including tape datasets. 4.

**Security Interface:** This component integrates with z/OS security systems (RACF, ACF2, Top Secret) for authentication and authorization. These components communicate through internal subroutine calls and data structures. SLiKZip does not use external databases; it relies on z/OS datasets for storage.

The utility integrates with z/OS SMF for audit logging. Configuration files define default settings for compression levels, encryption methods, and character set conversions. zip) COMPRESSLEVEL(9) ENCRYPT(AES256)`.

Competing products include CA Compress and FDRComp. SLiKZip's support for DEFLATE64 and its integration with z/OS security and logging facilities are key differentiators.
