When it comes to enterprise security and even home security, encryption is one of the essentials from corporate security to shopping online via the internet.
For many, encryption is a transparent technology that is relied upon as being adequate for the task, but the truth is that encryption is a technology that remains relatively misunderstood and many misconceptions exist about cryptography in general.

To start with, encryption is only part of the process required to ensure that data is secure. As with any form of protection, an item is only secure as long as no one has access – encryption is similar in that it uses keys to ‘lock’ up the data which can only be solved if you have the appropriate key.

This technique is known as symmetric or private key encryption. When files are encrypted, the creator uses a private-key to encrypt and decrypt the file. This private key is then shared to those who need to decrypt the file or send encrypted messages back to the original creator. Symmetric key cryptography is both highly efficient and secure when used with appropriate key management techniques.

On the other hand, in direct parallel is asymmetric encryption or public key cryptography, which was devised in the 1970s. This technique uses two sets of keys, one to encrypt and one to decrypt.
Public key /private key cryptography is use of asymmetric key algorithms because the key used to encrypt a message is not the same as the key used to decrypt it.

Each side has a private key which is kept secret, and a public key which can be widely distributed.

Messages are encrypted with the recipient’s public key and can only be decrypted with the corresponding private key. The keys are related mathematically, but if implemented properly, the private key cannot be obtained from the public key.

The following diagram illustrates how asymmetric encryption works:

Bob encrypts a message using Alice’s public key. That public key can only be used for encryption, not for decryption. Alice uses her private key to decrypt the message.

Gold Lock products use a mixture of these techniques to ensure absolute and total security, which parallels NSA and Military standards. The progress that made by Gold Lock has created a uniform solution when it comes to economically securing not just data but all forms of communication (Voice, Text, Files, and Emails).
