On June 18, 2026 a patent application published that does not describe a new cipher, a key-exchange scheme, or a signature algorithm. It describes a way to find the cryptography a development team is already shipping. Titled "Monitoring and Managing Cryptographic Libraries in Software Development," the application is assigned to DigiCert, Inc. and carried at US20260169731A1. Before anything else, the important label: this is a published application, not a granted patent. It establishes what DigiCert filed and asked an examiner to consider, not anything it can yet enforce. With that fixed, the interesting question is what the application is directed to.

The disclosed approach is, in plain terms, a cryptographic-discovery tool that lives inside the source-code repository rather than scanning a finished binary. As described, a monitoring agent is integrated with a version-control system as a hook or plugin and triggers on version-control events — commits, pushes, or merges. On each trigger it observes code changes in real time, analyzes the newly added or modified files to detect cryptographic libraries and the cryptographic functions they call, and generates alerts when it sees a cryptographic component that has been introduced, deprecated, or flagged as vulnerable. The named inventor is Avesta Hojjati, who appears across much of DigiCert's recent filing record. The shape of the disclosure is a continuous-integration control: catch the crypto at the moment a developer writes it into the repo, not months later in an audit.

Systems and methods for monitoring and managing cryptographic libraries within a version control system include steps of subsequent to integrating a monitoring agent with the version control system as a hook or plugin that triggers upon one or more version control events including commits, pushes, or merges, continuously observing code changes in real-time as source code is committed to the version control system; analyzing newly added or modified files within the committed code to detect cryptographic libraries and associated cryptographic functions; and generating alerts upon detection of introduced, deprecated, or vulnerable cryptographic components.— Monitoring and Managing Cryptographic Libraries in Software Development, US20260169731A1

The CPC class tells you where this lands

The classification is the tell. This application is classified under G06F 8/71 — software configuration management, the subclass for version control and managing changes to source code. It is not classified under H04L 9/, the cryptographic-mechanism family where DigiCert files most of its certificate and key-management work, nor under the G06F 21/ security subclass for protecting data and computers. That placement is consistent with the disclosure: the claimed contribution is not a cryptographic primitive but a development-pipeline mechanism that happens to be looking for cryptography. In landscape terms, it sits at the intersection of DevOps tooling and what the industry calls a cryptographic bill of materials — an inventory of every crypto dependency in a codebase. The application is directed to building that inventory continuously, from inside the commit history, and raising an alert the moment a deprecated or vulnerable library enters the tree.

Read against DigiCert's own recent record, the single G06F 8/71 filing reads less like an outlier and more like the front end of a larger theme. The same publication and assignee cluster contains a run of applications directed at moving existing systems off classical cryptography and onto quantum-safe schemes. US20260113205A1, "Seamlessly Transitioning to Post-Quantum Cryptography (PQC) in Digital Certificate Management" (classified under H04L 9/3265 and H04L 9/3249), is directed to automatically transitioning an end entity from a current cryptography scheme established over one certificate chain to a new scheme established over an alternate certificate chain when a flag is set and a certificate is up for reissue. US20260100823A1 is directed to offloading the authentication and session-key negotiation for a post-quantum encryption algorithm to a remote Secure Key Service (H04L 9/0852, H04L 9/32). The throughline is migration mechanics: how an installed base actually gets from RSA-and-ECC to PQC without manual rework.

A cluster directed at the post-quantum transition

The quantum-safe theme deepens further down the cluster. US20260046116A1, "Distributed Seed Storage for Quantum-Safe Private Key Generation on Constrained Devices" (H04L 9/0825, H04L 9/0852), is directed to deriving a private key for a quantum-safe algorithm by combining seeds provisioned at manufacturing with seeds delivered during a later update — aimed at IoT devices and tracker tags that cannot easily store a full key. US20250373411A1 is directed to protecting documents and code that were already signed with a classical algorithm by hashing them and re-signing the hash with a PQC private key, wrapping a quantum-vulnerable signature in a quantum-resistant one (H04L 9/3247). And US20250371170A1 is directed to tracking the one-time signatures of stateful hash-based schemes — Leighton-Micali (LMS) and the extended Merkle Signature Scheme (XMSS) — on a distributed ledger so a given one-time key is never reused (G06F 21/602). Stateful hash-based signatures are among the post-quantum schemes whose central operational hazard is exactly that reuse problem, and this application is directed to a bookkeeping mechanism for it.

A nearer-term certificate-handling filing rounds out the picture. US20260106753A1, "Public Key Cryptography with Password Protection" (H04L 9/14, H04L 9/3263), is directed to a modified PKCS #12 file-formatting scheme in which a user password is itself transmitted encrypted under a public key, decrypted server-side, and then used to protect the issued certificate and private key. Across these records, the CPC spread is informative: a payload of H04L 9/ subclasses for the cryptographic operations themselves, a G06F 21/602 placement for the signature-tracking record, and — for the hero of this week's drop — a G06F 8/71 placement that puts the discovery problem in the build pipeline rather than in the crypto layer.

What the hero application claims, then, is narrower and more specific than "crypto inventory": a version-control-integrated agent, triggered by commit-class events, that detects cryptographic libraries and functions in changed files and alerts on introduced, deprecated, or vulnerable components. Whether the claims that ultimately issue track the published language is a question for prosecution, and the scope an examiner allows may be narrower than the disclosure reads. For the purpose of reading the record as filed, the coverage is plain on its face, and its company is unambiguous: it published alongside a cluster of DigiCert applications directed, repeatedly, at the operational problem of getting deployed cryptography ready for a post-quantum world. The discovery tool is the step that comes first — you cannot migrate the crypto you cannot see — and this is the application that is directed to seeing it.
