The application that wrote it is gone
Decommissioned, or the vendor left. The encrypted archive remains, in a format nobody in the building has touched in years, and nobody wants to be the one who breaks it.
ANKASecure© modernizes legacy cryptographic estates in four steps without the originating application: PKCS#12 keystores are imported through a seven-stage validation pipeline that reports certificate status and migration path and accepts expired material by design; each PKCS#7 archive is analyzed for the algorithms and key references it uses; the archive is converted to a JOSE-based representation (JWE/JWS with extended identifiers) in streaming with bounded memory, the data key re-wrapped inside the control plane and the payload never decrypted to storage, log or caller; and the transition is bridged by retiring rather than destroying the old keys so original envelopes stay readable under policy. Every import, analysis and conversion is recorded in a signed, tamper-evident audit trail. Discovery of which archives exist is delivered by ANKATech channel partners.
Twenty years of PKCS#7 archives, one governed format.
The system that wrote them is gone, the vendor with it, and the certificate is expiring on data the business cannot lose. ANKASecure© imports the keys, converts the archives to a JOSE-based representation in streaming — without plaintext — and puts the result under policy, while the originals stay readable.

Is this you
Three ways this lands on your desk
A certificate is expiring on data that must stay readable
Retention says ten more years. The key material says eighteen months. Renewal is not an option when the issuing system no longer exists.
A modernization program stalls on one question
“And the encrypted archive?” Every plan to move the platform stops at the data that was encrypted under the old one.
Who signs this: A head of platform engineering or a modernization program owner with a decommissioning date, and a CISO who has to approve what happens to the archive. If the honest plan for the legacy data is “leave it where it is”, this is the conversation.
How it works
Four moves, none of them a rewrite
Import, analyze, convert, bridge. The originating application is not needed at any step, and the plaintext is never written anywhere.
Import the keys, including the expired ones
ANKASecure© imports PKCS#12 keystores through a seven-stage validation pipeline that reports each certificate’s real status and its migration path. Expired material is imported deliberately, because data encrypted under it still has to be readable.
Analyze what each archive actually uses
Before converting anything, ANKASecure© reads the PKCS#7 structure and reports the algorithms, the key references and the migration path per item — compact or streaming — so the conversion is planned against what is there, not against what the documentation said.
- analyzePkcs7
- streaming analysis
- per-item migration path
- Patent pending
Convert to a JOSE-based representation, in streaming
The PKCS#7 envelope is converted to JWE/JWS with extended identifiers, under a key the policy approves. The data key is re-wrapped inside the control plane; the payload streams with bounded memory and is never decrypted to storage, to a log or to the caller.
- PKCS#7 → JOSE
- streaming, bounded memory
- no plaintext egress
Bridge the transition
Old keys are retired, not destroyed, so the original envelopes stay readable for as long as the policy says. New writes go to the governed format. Both coexist under one policy until the last archive is converted — and the audit trail links each conversion to its source.
Fifteen minutes
What you will actually watch
Live, on a real deployment, with an archive shaped like yours. Nothing in this list is a mock-up or a roadmap item.
A PKCS#7 archive from a decommissioned system, and the PKCS#12 keystore that goes with it.
The keystore is imported: seven validation stages, the certificate reported as expired, the migration path named.
The archive is analyzed, then converted to the JOSE-based representation. Memory stays flat while it streams.
The converted envelope opens under a policy-approved key. The original still opens too, because its key was retired and not destroyed.
The audit trail: import, analysis and conversion, signed, each linked to its source.
Your archive, discussed on the deployment rather than on a slide.
What it rests on
The capabilities underneath, with their state
Shipping
PKCS#7 analysis and conversion to JOSE
Compact and streaming; the conversion re-wraps the data key inside the control plane with no plaintext egress.
Shipping
PKCS#12 import
Seven-stage validation pipeline with certificate status and migration-path analysis; expired material accepted by design.
Shipping
Re-encryption and re-signing without plaintext exposure
Compact and streaming, bounded memory at any file size.
Shipping
Key lifecycle with retirement
A retired key still decrypts what it protected; only destruction removes that, and destruction is a separate, audited step.

The framework
Where this sits in CAPA
The Cryptographic Control Plane reference architecture describes each pillar through the scenarios it must handle and one practical test. This solution is the modernization pillar’s scenarios, taken literally.
03
Primary pillar
Frictionless Modernization
Scenario realised
Migrating legacy cryptographic infrastructure
Practical test
“Can the protection of data encrypted years ago be changed today, without the originating application and without plaintext at rest?”
04
Supporting pillar
Cryptographic Governance & Compliance
Scenario realised
Enforcing a new enterprise security requirement
Practical test
“Can the organization prove, by querying the control plane, which policy applied to a given operation, and change that policy centrally?”

Maturity move
From algorithms and formats embedded in systems nobody can change to data held in a governed representation under a Control Plane. This is the step that makes every later level possible for the archive.
What this does not do
It does not recover data whose key is lost. Conversion needs the original key material; without it there is nothing to re-wrap, and no control plane changes that.
It does not reach archives held by a system that will not delegate the operation. Data stays where it is until that system, or a copy of its data, is brought under the plane.
It does not certify you. ANKASecure© maps its controls to NIST CSWP 39, the GSA PQC Buyer’s Guide and OWASP and hands you the evidence; the determination is still your auditor’s.
After this
The same installation already does these
No new deployment, no second contract for the platform. Once the archive is in the governed format, everything else is a policy change.
Bring the archive nobody wants to touch.
