- Method Detail
  - init
```
void init()
```
    Initializes the KEM and generates a new key pair.
  - getPublicKey
```
byte[] getPublicKey()
```
    Gets the KEM public key.
    
    Returns:
    
    the KEM public key.
  - extractSecret
```
byte[] extractSecret(byte[] encapsulated)
```
    Extracts the secret from an encapsulation ciphertext.
    
    Parameters:
    
    encapsulated - ciphertext to process.
    
    Returns:
    
    the secret from an encapsulation ciphertext.
    
    Throws:
    
    java.lang.IllegalArgumentException - if encapsulated doesn't have the expected length
    
    java.lang.NullPointerException - if encapsulated == null
  - getEncapsulationLength
```
int getEncapsulationLength()
```
    Gets the required encapsulation length in bytes.
    
    Returns:
    
    the length required for a valid encapsulation ciphertext.
