Encryption is a key component of most security plans and implementations.  In order to effectively secure data, either during transmission or storage, that data often needs to be converted into a format that is not readable except by secret key – either known or negotiated.  While a wide variety of encryption algorithms are available, the ideal algorithm for a particular application will vary depending on the speed vs security tradeoff.  Higher security algorithms often take more time to encrypt a payload, while lower security algorithms allow faster execution speeds.  Depending on the nature of the data and the length of storage, a different algorithm might work better for a  particular scenario.

The most popular algorithm for real-time encryption over data transmission is SSL/TLS.  TLS both secures a connection and verifies the remote endpoint in order to prevent spoofing.  The connection is often secured with a proven algorithm such as AES, while endpoint verification is done through chain-of-trust certificate servers.  Real-time encryption has enabled high-security applications such as banking and credit card processing over insecure data lines such as public Wifi networks.

Offline or asynchronous encryption, on the other hand, poses a different challenge.  While much of the data in real-time encryption is transient and has little value for an attacker to decrypt, the data encrypted for storage is often the most sensitive.  Whether the data contains health information, passwords, personally identifiable information, or financial information, a hacker who accessed the storage network and was able to successfully decrypt the data could use the data for either their own financial gain, or damage to the data stakeholders.  Offline encryption algorithms require higher levels of security, due to the longer time that an attacker has to decrypt a particular packet.  Brute force or rainbow table attacks are feasible on offline data stores, creating more stringent data protection requirements.
