Enclosing class:
AlgorithmFilter
public static final class AlgorithmFilter.Builder extends Object
Builder for constructing AlgorithmFilter instances.

All methods return the builder for fluent chaining.

  • Method Details

    • withCategory

      public AlgorithmFilter.Builder withCategory(AlgorithmInfo.Category category)
      Filter by algorithm category.
      Parameters:
      category - POST_QUANTUM or CLASSICAL
      Returns:
      this builder

    • withStatus

      public AlgorithmFilter.Builder withStatus(AlgorithmInfo.Status status)
      Filter by lifecycle status.
      Parameters:
      status - RECOMMENDED, LEGACY, or EXPERIMENTAL
      Returns:
      this builder

    • withMinSecurityLevel

      public AlgorithmFilter.Builder withMinSecurityLevel(int level)
      Filter by minimum NIST security level (inclusive).
      Parameters:
      level - minimum level (1, 3, or 5)
      Returns:
      this builder

    • withMaxSecurityLevel

      public AlgorithmFilter.Builder withMaxSecurityLevel(int level)
      Filter by maximum NIST security level (inclusive).
      Parameters:
      level - maximum level (1, 3, or 5)
      Returns:
      this builder

    • withSecurityLevel

      public AlgorithmFilter.Builder withSecurityLevel(int level)
      Filter by exact NIST security level.
      Parameters:
      level - exact level (1, 3, or 5)
      Returns:
      this builder

    • withKeyOps

      public AlgorithmFilter.Builder withKeyOps(String... ops)
      Filter by required key operations (AND logic). Algorithm must support ALL specified operations.
      Parameters:
      ops - operations to require (e.g., "encrypt", "decrypt", "sign", "verify")
      Returns:
      this builder

    • withStandards

      public AlgorithmFilter.Builder withStandards(String... standards)
      Filter by required standards compliance (AND logic). Algorithm must be endorsed by ALL specified standards.
      Parameters:
      standards - standards to require (e.g., "NIST", "BSI", "ANSSI")
      Returns:
      this builder

    • withKty

      public AlgorithmFilter.Builder withKty(String... ktyValues)
      Filter by key types (OR logic). Algorithm matches if its kty equals ANY specified value.
      Parameters:
      ktyValues - key types (e.g., "ML-KEM", "ML-DSA", "RSA", "EC")
      Returns:
      this builder

    • withCompositeMode

      public AlgorithmFilter.Builder withCompositeMode(CompositeMode... modes)
      Filter by composite construction (OR logic). A hybrid algorithm matches if its compositeMode equals ANY specified value; a simple algorithm never matches, because it has no construction.

      This is the criterion that separates hybrid KEMs from hybrid signatures. Filtering on kty cannot: every hybrid entry publishes the same coarse COMPOSITE token.

      Parameters:
      modes - composite constructions to match; must not be null, and individual null elements are ignored
      Returns:
      this builder
      Throws:
      NullPointerException - if modes is null

    • withAlg

      public AlgorithmFilter.Builder withAlg(String... algValues)
      Filter by algorithm names (OR logic). Algorithm matches if its alg equals ANY specified value.
      Parameters:
      algValues - algorithm names (e.g., "ML-KEM-768", "RSA-4096")
      Returns:
      this builder

    • build

      public AlgorithmFilter build()
      Builds the AlgorithmFilter instance.
      Returns:
      a new AlgorithmFilter with the configured criteria
