Enum Class SlhDsaKeyGenSpec.PreHash

java.lang.Object

java.lang.Enum<SlhDsaKeyGenSpec.PreHash>

zeroecho.core.alg.slhdsa.SlhDsaKeyGenSpec.PreHash

All Implemented Interfaces:

Serializable, Comparable<SlhDsaKeyGenSpec.PreHash>, Constable

Enclosing class:

SlhDsaKeyGenSpec

public static enum SlhDsaKeyGenSpec.PreHash
extends Enum<SlhDsaKeyGenSpec.PreHash>

Optional pre-hash variant selection.

Bouncy Castle exposes "with hash" variants as distinct parameter specs, for example slh_dsa_sha2_128s_with_sha256.

Valid combinations depend on the hash family and security strength:

• SHA2-128 uses SHA-256
• SHA2-192/256 use SHA-512
• SHAKE-128 uses SHAKE128
• SHAKE-192/256 use SHAKE256
