Complete the steps with a synthetic example before using real data. Checkmarks live only in this tab.
Set purpose and retention boundaries before packaging evidence
An evidence package should reconstruct a defined event, not collect every log line. State the time range, system, incident identifier, decision owner, and intended recipients first.
Real tokens, session cookies, private keys, customer data, and unnecessary bodies do not belong in the shared package. Keep an access-controlled original separately and redact the working copy.
- Define the incident question in one sentence.
- Choose the shortest necessary time range.
- Separate original and sharing copy.
Use secret scanning for prioritization, not a verdict
Diff and text scans can flag key shapes, high-entropy strings, and known prefixes. No finding does not prove that secrets are absent; custom formats, split values, and binaries need separate review.
For every finding, record whether to remove it, partially display it, replace it consistently, or retain it only in an authorized channel. Consistent placeholders may themselves enable correlation.
Use hashes to check integrity, not provenance
A SHA-256 digest helps compare whether a shared file changed in transit. It cannot prove who created the file, whether its claims are true, or whether the originating device was compromised.
A manifest should include filename, byte size, digest, creation time, and redaction-rule version. Protect the manifest because filenames and timing can still reveal context.
Separate observation, inference, and obligation in the timeline
For each entry, keep source timezone, observed event, confidence, and missing information distinct. Do not present an inference such as 'breach began' as though it were a raw log event.
A notification-timeline tool provides date arithmetic and prompts only; it does not decide legal awareness or duty. Authorized teams must apply current law, contracts, and incident facts.
Tools and responsibilities in this workflow
Each tool contributes different evidence; no single output approves the whole workflow. Start with synthetic data, apply the acceptance check, and stop when a boundary is exceeded.

Turn the guide into a repeatable review
Use this 4-tool review plan for “Safe Incident-Evidence Handover Without Uploading Logs”. Goal: A guide to preparing a safer incident package with local secret pre-scans, a redaction plan, hash comparison, and a bounded timeline. Start with a safe example instead of real data, then record each expected result and acceptance decision.
Git Diff Secret Scanner
- Prepare
- Load the safe example or enter your own data. Expected format for Git Diff Secret Scanner: For Git Diff Secret Scanner, provide synthetic or minimized code, configuration, identifiers, or file content you are authorized to review. The requested outcome is to find high-signal secret patterns only in added diff lines..
- Apply
- Run it on-device and inspect errors, warnings, and metrics. Git Diff Secret Scanner applies this method: Git Diff Secret Scanner uses this disclosed method to find high-signal secret patterns only in added diff lines: content is not executed; only explainable static patterns and bounded browser operations are applied.
- Acceptance check
- Validate the output in the target environment and with edge cases. Acceptance check for Git Diff Secret Scanner: Before accepting a Git Diff Secret Scanner result, complete manual review at the source location and independent verification with an appropriate professional security tool or authorized process; the evidence should support the goal to find high-signal secret patterns only in added diff lines..
- Expected output
- When Git Diff Secret Scanner finishes, it returns evidence locations, severity, false-positive considerations, and the next verification action, organised around the goal to find high-signal secret patterns only in added diff lines.. Find high-signal secret patterns only in added diff lines.
Secret Redaction Planner
- Prepare
- Enter only content you are authorized to inspect. Expected format for Secret Redaction Planner: For Secret Redaction Planner, provide synthetic or minimized code, configuration, identifiers, or file content you are authorized to review. The requested outcome is to turn key, token, and connection-string candidates into a type-aware redaction plan..
- Apply
- Run the bounded local scan. Secret Redaction Planner applies this method: Secret Redaction Planner uses this disclosed method to turn key, token, and connection-string candidates into a type-aware redaction plan: content is not executed; only explainable static patterns and bounded browser operations are applied.
- Acceptance check
- Independently verify critical findings. Acceptance check for Secret Redaction Planner: Before accepting a Secret Redaction Planner result, complete manual review at the source location and independent verification with an appropriate professional security tool or authorized process; the evidence should support the goal to turn key, token, and connection-string candidates into a type-aware redaction plan..
- Expected output
- When Secret Redaction Planner finishes, it returns evidence locations, severity, false-positive considerations, and the next verification action, organised around the goal to turn key, token, and connection-string candidates into a type-aware redaction plan.. Turn key, token, and connection-string candidates into a type-aware redaction plan.
File Hash Calculator & Comparator
- Prepare
- Choose one file up to 100 MB and optionally a second for comparison. Expected format for File Hash Calculator & Comparator: For File Hash Calculator & Comparator, provide local file or files of a supported type within the disclosed size limit. The requested outcome is to calculate SHA-256 for one or two files and compare integrity locally..
- Apply
- Calculate SHA-256 on your device. File Hash Calculator & Comparator applies this method: File Hash Calculator & Comparator uses this disclosed method to calculate SHA-256 for one or two files and compare integrity locally: the file is read in browser memory and a new output is created without overwriting the original.
- Acceptance check
- Compare it with an expected value obtained through a separate trusted channel. Acceptance check for File Hash Calculator & Comparator: Before accepting a File Hash Calculator & Comparator result, complete preserving the original and checking that output opens correctly, retains expected pages or frames, size, and visible quality; the evidence should support the goal to calculate SHA-256 for one or two files and compare integrity locally..
- Expected output
- When File Hash Calculator & Comparator finishes, it returns a downloadable new file, size and format metrics, and disclosed processing limits, organised around the goal to calculate SHA-256 for one or two files and compare integrity locally.. Calculate SHA-256 for one or two files and compare integrity locally.
Breach Notification Timeline
- Prepare
- Load the safe example or enter your own data. Expected format for Breach Notification Timeline: For Breach Notification Timeline, provide a date, time, duration, or schedule with an explicit format and time zone. The requested outcome is to show elapsed time and decision points awaiting documented review..
- Apply
- Run it on-device and inspect errors, warnings, and metrics. Breach Notification Timeline applies this method: Breach Notification Timeline uses this disclosed method to show elapsed time and decision points awaiting documented review: calendar, time-zone, and inclusion rules are calculated separately.
- Acceptance check
- Validate the output in the target environment and with edge cases. Acceptance check for Breach Notification Timeline: Before accepting a Breach Notification Timeline result, complete uTC equivalence, daylight-saving transitions, boundary dates, and applicable official calendar rules; the evidence should support the goal to show elapsed time and decision points awaiting documented review..
- Expected output
- When Breach Notification Timeline finishes, it returns a normalized temporal value, calculation summary, and ambiguous-zone warnings, organised around the goal to show elapsed time and decision points awaiting documented review.. Show elapsed time and decision points awaiting documented review.
Apply this boundary to Git Diff Secret Scanner: Git Diff Secret Scanner limitation: Code is not executed, and no finding does not prove the absence of vulnerabilities. If that condition is not met, do not pass the output to the next workflow step.
For “Safe Incident-Evidence Handover Without Uploading Logs”, record the tool, selected setting, browser version, and acceptance or rejection reason for “Auditable pre-publication quality control: local analysis with Git Diff Secret Scanner”—not the sensitive content. This keeps the review repeatable without copying real data.
