So the client generates a session key, then encrypts a copy of it and sends it to the server where it can be decrypted and used for communicating throughout the duration of the connection (or until its rotated out).

Owing to the computing power asymmetric keys require, its more practical ( and still safe ) to use smaller symmetric keys for the actual communication portion of the connection. This means there are two encryption keys that each handle one half of the process: a public key for encryption, and a private key for decryption.Įvery SSL certificate contains a public key that can be used by the client to encrypt data, and the owner of said SSL certificate securely stores a private key on their server which they use to decrypt that data and make it readable. Or put another way, SSL certificates bind a specific public key to an identity. The SSL certificate file is tasked with providing the necessary information needed for authentication. The hashes you have seen thus far are NOT SHA hashes of any type.įor succinctness, it seems SSL is often explained as encryption. Unique meaning that two different pieces of data can never produce the same hash the next section explains why this is so important.

Irreversible meaning that if you only had the hash you couldnt use that to figure out what the original piece of data was, therefore allowing the original data to remain secure and unknown. It is easier for the computer to first compute a hash and then compare the values than it would be to compare the original files.Īny computer in the world that understands the hashing algorithm you have chosen can locally compute the hash of our example sentence and get the same answer. These include employee retirement plans, medical coverage, dental, vision, and short-term and long-term disability.Įven changing one bit of a multi-thousand gigabyte document would result in an entirely different hash. The certification process is built upon 40 years of empirical research on the competencies and job functions that are vital to the counselors performance.Ī passing score on the CRC certification exam ensures that applicants meet nationally-accepted, key competency standards based on current practice in the field. Participation in continuing education ensures that all CRCs continue to expand their skills.
