WebCryptography can roughly be divided into symmetric key and public key (asymmetric key) cryptographies. The symmetric key cryptography uses the same secret key for encryption and decryption. With the processing that is relatively lightweight, it is used in data encryption and authentication. WebIn cryptography, a round or round function is a basic transformation that is repeated multiple times inside the algorithm.Splitting a large algorithmic function into rounds simplifies both implementation and cryptanalysis.. For example, encryption using an oversimplified three-round cipher can be written as = ((())), where C is the ciphertext and P is the plaintext.

WebBLS digital signature. A BLS digital signature —also known as Boneh–Lynn–Shacham [1] (BLS)—is a cryptographic signature scheme which allows a user to verify that a signer is authentic. The scheme uses a bilinear pairing for verification, and signatures are elements of an elliptic curve group.
