Record Class HybridSignatureProfile

java.lang.Object

java.lang.Record

zeroecho.sdk.hybrid.signature.HybridSignatureProfile

Record Components:

classicSigId - canonical identifier of the classical signature algorithm (for example "Ed25519")

pqcSigId - canonical identifier of the post-quantum signature algorithm (for example "ML-DSA-65")

classicSpec - optional ContextSpec for the classical signature engine; may be null

pqcSpec - optional ContextSpec for the post-quantum signature engine; may be null

verifyRule - aggregation rule applied during verification

public record HybridSignatureProfile(String classicSigId, String pqcSigId, ContextSpec classicSpec, ContextSpec pqcSpec, HybridSignatureProfile.VerifyRule verifyRule)
extends Record

Immutable definition of a hybrid signature composition. HybridSignatureProfile is a pure configuration object that defines:

• which two signature algorithms participate in the hybrid composition,
• their fixed ordering within the produced signature trailer,
• the verification aggregation rule applied to their results.

The profile is the single source of truth for hybrid signature processing. No algorithm identifiers or metadata are embedded in the signature trailer itself; both signing and verification sides must use the same profile.

Instances of this record are immutable and thread-safe.

Constructor Details

HybridSignatureProfile

public HybridSignatureProfile(String classicSigId,
 String pqcSigId,
 ContextSpec classicSpec,
 ContextSpec pqcSpec,
 HybridSignatureProfile.VerifyRule verifyRule)

Canonical constructor with invariant checks.

Uses Objects.requireNonNull(Object, String) to enforce mandatory components while keeping validation idiomatic and consistent with the rest of the ZeroEcho codebase.

Throws:

NullPointerException - if classicSigId, pqcSigId, or verifyRule is null

Method Details

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

classicSigId

public String classicSigId()

Returns the value of the classicSigId record component.

Returns:

the value of the classicSigId record component

pqcSigId

public String pqcSigId()

Returns the value of the pqcSigId record component.

Returns:

the value of the pqcSigId record component

classicSpec

public ContextSpec classicSpec()

Returns the value of the classicSpec record component.

Returns:

the value of the classicSpec record component

pqcSpec

public ContextSpec pqcSpec()

Returns the value of the pqcSpec record component.

Returns:

the value of the pqcSpec record component

verifyRule

public HybridSignatureProfile.VerifyRule verifyRule()

Returns the value of the verifyRule record component.

Returns:

the value of the verifyRule record component
