Jacquelin Potier is an independent Windows utility author whose compact, no-install tools address two perennial system-administration pain points: untangling library dependencies and performing quick, offline cryptographic operations. All DLLs Dependencies walks through Portable Executable headers to draw a tree of every implicit and delay-loaded DLL a binary requests, flagging missing redistributables, bitness mismatches, or side-by-side manifest problems long before the “missing api-ms-win-…” error appears on a client machine; release engineers routinely drop the single 200 k executable into CI pipelines to validate that freshly compiled ports still carry the correct Visual C++ runtime references. Crypto Stuff supplies an equally lightweight GUI for the opposite end of the stack—hashing, symmetric ciphering, RSA, and Elliptic Curve primitives—making it convenient for developers who need to generate a quick SHA-256 checksum, AES-encrypt a configuration blob, or verify an ECDSA signature without spinning up OpenSSL or Python scripts. Both programs are fully portable, keep no registry entries, and run from a thumb drive on air-gapped PCs, so auditors and malware analysts can inspect suspicious files or create fingerprints without altering the host. Jacquelin Potier’s software is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always install the latest upstream build, and can be queued for batch installation alongside other utilities.
