![]() ![]() There are two versions of this algorithm that are SHA 1 and SHA 2 and these two differ in the number of bits or the length of the hashed output. And SHA is the cryptographic algorithm accepted for digital signatures. This is why the TLS( Transport Layer Security) protocol implements strong authentication with cryptography. i.e knowing that on the other end is genuinely the same person you want to communicate with. We know authentication is the most significant point in electronic communication. Simply said, these algorithms are designed to keep your data secure and are a family of cryptographic functions. SHA or Secure Hash Algorithm is another algorithm that is used to hash data and certificate files using hash functions. Yes, it’s a different thing that CRC is quite popular because it is effective in detecting errors and easy to execute with simple mathematical analysis. ![]() Now since most of us may not have the knowledge of complex algorithms and how to implement digital circuits… we likely would want to remove it from our context menu. Cyclic Redundancy Check in short for CRC is a method or process by which accidental changes or errors in the communication channel are detected using generator polynomials that are available on both sender and receiver sides.
