public class FrodoKEMEngine
extends java.lang.Object
```
FrodoKEM as standardised in ISO/IEC 18033-2:2006/Amd 2:2026, Clause 14, for the SHAKE parameter sets at security levels 976 and 1344. A single engine implements both the salted "FrodoKEM" (Salted Fujisaki-Okamoto transform) and the ephemeral "eFrodoKEM" (no salt) variants, selected by the salted flag: when salted, the seed seedSE is enlarged to 2*len_mu bits and a salt of 2*len_mu bits is folded into the G_2 hash and the shared secret and carried in the ciphertext; when not salted, len_salt is zero and every salt operation below is a no-op.
