FrodoKEM-976-AES key encapsulation mechanism wrapper class
FrodoKEM976AES
High-level wrapper for FrodoKEM-976-AES KEM operations. Provides secure key generation, encapsulation, and decapsulation with automatic memory management.
Memory Management:

Generate a new FrodoKEM-976-AES keypair
If instance is destroyed
If key generation fails
const { publicKey, secretKey } = kem.generateKeyPair();console.log('Public key:', publicKey.length); // 15632 bytesconsole.log('Secret key:', secretKey.length); // 31296 bytes Copy
const { publicKey, secretKey } = kem.generateKeyPair();console.log('Public key:', publicKey.length); // 15632 bytesconsole.log('Secret key:', secretKey.length); // 31296 bytes
Encapsulate a shared secret using a public key
Public key (15632 bytes)
If public key size is invalid
If encapsulation fails
const { ciphertext, sharedSecret } = kem.encapsulate(publicKey);console.log('Ciphertext:', ciphertext.length); // 15744 bytesconsole.log('Shared secret:', sharedSecret.length); // 24 bytes Copy
const { ciphertext, sharedSecret } = kem.encapsulate(publicKey);console.log('Ciphertext:', ciphertext.length); // 15744 bytesconsole.log('Shared secret:', sharedSecret.length); // 24 bytes
Decapsulate a shared secret using a secret key
Ciphertext (15744 bytes)
Secret key (31296 bytes)
Shared secret (24 bytes)
If ciphertext or secret key size is invalid
If decapsulation fails
const sharedSecret = kem.decapsulate(ciphertext, secretKey);console.log('Recovered secret:', sharedSecret.length); // 24 bytes Copy
const sharedSecret = kem.decapsulate(ciphertext, secretKey);console.log('Recovered secret:', sharedSecret.length); // 24 bytes
