Enforce a TLS 1.3 floor

Recipe IDio.moderne.cryptography.pqc.EnforceTls13

Artifactio.moderne.recipe:rewrite-cryptography

Rewrites JSSE, BouncyCastle and Spring Boot protocol configuration to a TLS 1.3 floor across Java, .properties and YAML sources, so that JEP 527 hybrid key exchange — which exists for TLS 1.3 only — can negotiate. Surfaces that cannot be rewritten safely are recorded as Report only rows rather than changed.

Usage

Run this recipe

This recipe has no required configuration options. Users of Moderne can run it via the Moderne CLI.

You will need to have configured the Moderne CLI on your machine before you can run the following command.

shell

mod run . --recipe EnforceTls13

Data tables

TLS protocol enforcement

io.moderne.cryptography.pqc.table.ProtocolEnforcementTable

Protocol configuration surfaces rewritten to a TLS 1.3 floor, and surfaces flagged as needing manual review because rewriting them would change behaviour in a way a source scan cannot justify. Rows describe declared configuration only: a JVM's java.security file, container -D flags and environment variables are invisible here, so an enforced source does not prove an enforced runtime.

Column	Description
Configuration surface	The API or configuration key that produced the row, e.g. SSLContext.getInstance, SSLSocket.setEnabledProtocols, SSLServerSocket.setEnabledProtocols, SSLEngine.setEnabledProtocols, SSLParameters.setProtocols, https.protocols, jdk.tls.client.protocols, jdk.tls.server.protocols, jdk.tls.disabledAlgorithms, AbstractTlsPeer.getSupportedVersions, server.ssl.enabled-protocols, server.ssl.protocol. The token vocabulary is shared with the TLS configuration inventory so discovery and enforcement rows can be joined.
Action	Rewritten when the recipe changed the source, or Report only when the surface was flagged but deliberately not transformed — a protocol array shared with non-TLS code, or a jdk.tls.disabledAlgorithms assignment that replaces rather than extends the JDK default list.
Protocols before	Comma-joined protocol tokens found before the change, e.g. TLSv1.1,TLSv1.2. BouncyCastle downTo ranges are expanded to their JSSE spelling, e.g. TLSv1.2,TLSv1.1,TLSv1. For a jdk.tls.disabledAlgorithms row this is the raw property value.
Protocols after	Comma-joined protocol tokens after the change, e.g. TLSv1.3, or TLSv1.3,TLSv1.2 where an exception retains TLS 1.2. Empty for Report only rows.
Code snippet	The source code of the detected API usage, e.g. Cipher.getInstance("DES").
Library name	The library providing the configuration surface: JSSE, BouncyCastle or Spring Boot.
Library language	The language of the source the row was found in: Java, Properties or YAML.
File location	The path of the source file relative to the repository root.
Start line	1-based line of the start of the API usage.
Start column	0-based column of the start of the API usage, or -1 when unavailable.
Start offset	0-based character offset of the start of the API usage, or -1 when unavailable.
End line	1-based line of the end of the API usage.
End column	0-based column of the end of the API usage, or -1 when unavailable.
End offset	0-based character offset of the end of the API usage, or -1 when unavailable.
Repository name	The repository name from Git provenance, e.g. payment-service. Empty when unknown.
Scan source	Where the source was scanned from, derived from Git provenance, e.g. GitHub, GitLab, Local Repository.
Branch	The branch from Git provenance, e.g. main. Empty when unknown.

Source files that had results

org.openrewrite.table.SourcesFileResults

Source files that were modified by the recipe run.

Column	Description
Source path before the run	The source path of the file before the run. null when a source file was created during the run.
Source path after the run	A recipe may modify the source path. This is the path after the run. null when a source file was deleted during the run.
Parent of the recipe that made changes	In a hierarchical recipe, the parent of the recipe that made a change. Empty if this is the root of a hierarchy or if the recipe is not hierarchical at all.
Recipe that made changes	The specific recipe that made a change.
Estimated time saving	An estimated effort that a developer to fix manually instead of using this recipe, in unit of seconds.
Cycle	The recipe cycle in which the change was made.

Source files that had search results

org.openrewrite.table.SearchResults

Search results that were found during the recipe run.

Column	Description
Source path of search result before the run	The source path of the file with the search result markers present.
Source path of search result after run the run	A recipe may modify the source path. This is the path after the run. null when a source file was deleted during the run.
Result	The trimmed printed tree of the LST element that the marker is attached to.
Description	The content of the description of the marker.
Recipe that added the search marker	The specific recipe that added the Search marker.

Source files that errored on a recipe

org.openrewrite.table.SourcesFileErrors

The details of all errors produced by a recipe run.

Column	Description
Source path	The file that failed to parse.
Recipe that made changes	The specific recipe that made a change.
Stack trace	The stack trace of the failure.

Recipe performance

org.openrewrite.table.RecipeRunStats
