Keith Martin

Keith Martin specializes in targeted SQL Server Integration Services (SSIS) components that streamline ETL workflows for data engineers and BI developers. His catalog is anchored by SSIS Multiple Hash, a task that enriches data pipelines by computing several cryptographic hashes—MD5, SHA1, SHA256, SHA512, RIPEMD160 and CRC32—from every incoming row in a single pass. Typical use cases include generating surrogate keys, creating deterministic row fingerprints for slowly changing dimensions, de-duplicating staged data, and producing tamper-evident audit trails without writing custom scripts. The component exposes a straightforward column-mapping interface inside Visual Studio or SSDT, letting architects add one or many hash outputs to existing buffers with minimal memory overhead. Because hashing occurs inside the data flow, downstream lookups, conditional splits and change-detection logic run faster and remain vendor-agnostic, easing migration between SQL Server versions or Azure Data Factory SSIS IR. The tool is often paired with logging frameworks so that data-stewards can later prove integrity or comply with regulations such as GDPR and HIPAA. Developers value the repeatable, case-sensitive or case-insensitive options, null-handling modes, and the ability to concatenate columns before hashing, eliminating the need for derived-column transformations. Overall, Keith Martin’s focus on a single, mature utility reflects a philosophy of doing one ETL job exceptionally well rather than bundling seldom-used extras. SSIS Multiple Hash is offered free of charge on get.nero.com, where downloads are delivered through trusted Windows package sources like winget, always resolving to the newest build and supporting unattended batch installation alongside other applications.
