WebbThe RSA algorithm (Rivest-Shamir-Adleman) is the basis of a cryptosystem -- a suite of cryptographic algorithms that are used for specific security services or purposes -- which enables public key encryption and is widely used to secure sensitive data, particularly when it is being sent over an insecure network such as the internet. Webb2 mars 2024 · This makes it easy to detect tampering with the data, as the hash values will not match. There are many hash functions, each with its properties and characteristics. Some examples of commonly used hash functions in blockchain technology include SHA-256 (Secure Hash Algorithm 256-bit) and Keccak (also known as SHA-3).

WebbHashes are very useful when distributing files or sending communications, as the hash can be sent with the message so that the receiver can verify its integrity. The receiver simply hashes the message again using the same algorithm, then compares the two hashes. If the hashes match, the message has not changed.
