Class SecretKey

java.lang.Object
com.codename1.security.Key
com.codename1.security.SecretKey
public final class SecretKey extends Key

A symmetric secret key. Used with Cipher (AES) and Hmac (via raw bytes). For asymmetric algorithms use PublicKey / PrivateKey.

Keys carry the raw key material plus the algorithm name they are intended for. They do not enforce length or strength -- that is the caller's responsibility, although KeyGenerator will produce keys of standard lengths.
