Lake County has average temperatures ranging from the low 30's in the winter to the high 90's to low 100's in the summer. An average humidity of 50% in the winter and 30% in the summer which means virtually none of that famous California fog.
They are lever locks, with between 6 and 12 levers. They are double bitted and asymmetric, so the lock essentially has two different sets of levers. In addition, they are mostly quadruple throw, so you need to pass 4 sets of levers. The bolt work has 2 or 4 hardened steel circular bolts, providing good saw resistance.
In symmetric systems the same key (the secret key) is used to encrypt and decrypt a message. Data manipulation in symmetric systems is faster than asymmetric systems as they generally use shorter key lengths. Asymmetric systems use public key to encrypt a message and a private key to decrypt it.Use of asymmetric systems enhances the security of communication. In colloquial use, the term  code  is often used to mean any method of encryption or concealment of meaning.ymmetric-key cryptography, where a single key is used for encryption and decryption. Symmetric-key cryptography refers to encryption methods in which both the sender and receiver share the same key (or, less commonly, in which their keys are different, but related in an easily computable way).
